I’ve played through every one of these rooms, and honestly, some of them had me stuck for way longer than I want to admit (looking at you, Level 96). Below is everything I learned along the way, written the way I’d explain it to a friend sitting next to me, not a manual. Grab your patience and let’s get through these doors.
Levels 1 to 10
Level 1
Nothing tricky here. There’s a red button by the door. Push it.
Level 2
Grab the globe and slide it to the right. That’s it, that’s the whole puzzle.
Level 3
See that tree? Click on it, then shake your mouse back and forth quickly like you’re actually rattling the branches. A key will drop out eventually. Pick it up and unlock the door with it.
Level 4
There’s a cart blocking your way, and it’s got blocks wedged under the wheels. Clear those out first, then you can drag the cart away from the door.
Level 5
Look for the brown bottle sitting on the desk. Nudge it until it tips over and shatters. That’s what’s hiding your key underneath.
Level 6
There’s a laptop on the table. Open it up and you’ll be playing tic-tac-toe. Win by getting three of your marks in a row, and the door opens.
Level 7
This one’s a matching game between athletes and their gear. Here’s how it breaks down:
| Player | Item |
|---|---|
| Basketball Player | Basketball |
| Hockey Player | Tennis Ball |
| Volleyball Player | Hockey Puck |
| Soccer Player | Volleyball |
| Tennis Player | Soccer Ball |
Yes, they’re all mismatched on purpose. That’s the joke of the level.
Level 8
There’s a pencil sitting on a pedestal next to a vase. Grab it and rub it over the blank canvas nearby, like doing a pencil rubbing, and a hidden code will show up. Punch that into the keypad next to the door. The code is 8972.
Level 9
You’re building a guitar from scratch. The neck is leaning against the counter on the lower left, the strings are on the floor below the door, and the body is sitting by the green chair on the right. Set the parts on the stand in this order: body first, then neck, then strings. Once it’s all together, the door opens on its own.
Level 10
There’s a chalkboard showing a pattern, and buttons on the floor to match it. Start on red and follow along: Red, Green, Green, Green, Red, Green, Red, Red, Green.
Levels 11 to 20
Level 11
Time to blow the door open, literally. Grab the sodium (Na) from the blue table, the water (H2O) from the counter, and the TNT from the desk in back. Pour the water onto the sodium to create sparks. Set the TNT down in front of the door, then drop the sparks onto it. The door blows open (well, sort of, it’s a game after all).
Level 12
The key’s hiding inside the red pot. Lift the lid off first, then grab the potholder hanging beside the door so you don’t burn your hand fishing the key out. Use that key on the door.
Level 13
You don’t actually need to zoom in for this one. The goal is to grow a flower that produces your key. Snip the rope on the smaller hanging plant using the shears from the bigger plant on the left (just click the shears, then click where you want to cut). Grab the seeds by the fountain statue, the spade stuck in the dirt on the right, and the watering can tucked under the shelf. Scoop dirt with the spade, drop it in the pot near the door, add the seeds, water it, and wait for your key to appear.
Level 14
Check the pocket of that hanging coat, there’s a note with the code written on it. Enter it into the keypad next to the door. The code is 194026.
Level 15
Click the butterfly painting to zoom in, then color it in to match the reference. Pick your color from the palette, then click the section you want to fill. Made a mistake? No worries, just color over it.
Level 16
There’s a key hidden in a box behind the bus, but you’ll need to move the bus first. Grab the funnel by the door and the gas can, pick up the keys from underneath the bus, then combine the funnel with the gas can.
Use the keys to open the side panel, fill the tank with gas, then use the keys again to start the engine. The bus rolls forward, revealing a grey box behind it. Take the key from that box to open the door.
Level 17
Same idea, a hidden key, this time in a grey box. Grab the bolt cutters from the box under the desk and cut the lock off the toolbox. Inside you’ll find two screwdrivers.
Grab the hex wrench from the bend in the pipe on the right, then click the grey box up on the shelf. Match each tool to its matching screw head to unlock the box, take the key, and open the door.
Level 18
- Count every butterfly in the room, there are more hiding than you’d think.
- Click the paper towel holder to reveal a blue one marked “x12,” that’s your multiplier. Check the curtain, the x-ray (click to zoom if it’s hard to make out), the one flying around, and the two mounted on the wall. Don’t forget the blue one itself, it counts too.
- Total butterflies: 20. Multiply by 12 and the code is 240.
Level 19
Drag the box left and right to catch basketballs as they fall. Grab six of them and the doors open. Miss and catch the wrong ball, and you’re starting over.
Level 20
Open the book on the desk to see a matching puzzle: weapons on the left, ammo on the right.
| Weapon | Fires |
|---|---|
| Rifle | Shells |
| Pistol | Lead Balls |
| Cannon | Cannonballs |
| Sling | Pebbles |
| Bow | Arrows |
| Trebuchet | Large Stones |
Levels 21 to 30
Level 21
Click the big map of Australia and it splits apart into pieces. Drag them back together into the shape of the country.
Level 22
You’re rebuilding a microscope from three scattered parts, one in the sink, one on the floor by the door, one on the middle shelf. Set the base down first, then the lens piece, then the head. Click the finished microscope to reveal your code. The code is 7290.
Level 23
Something’s blocking the door and you need to clean it up. Grab the dustpan and set it on the floor, then take the broom and sweep the mess into it by dragging back and forth. Once it’s clear enough, the door opens.
Level 24
The parrot knows the code, you just have to earn it. Grab the spoon from under the white table, the crowbar leaning against the cupid fountain, and the knife sticking up on the right side of the room. Pry open the crate with the crowbar, slice the bag inside with the knife, then scoop out seed with the spoon and feed the parrot. If it doesn’t talk right away, just feed it again. The code is 48575.
Level 25
There’s a dog parked right in front of the door and it’s not moving on its own. Grab the ladder on the far left and set it under the tree, then pick up the can of dog food hiding in the branches. Drop that food in the dog’s bowl and it’ll finally wander off.
Level 26
- Click the pictures on the easel to zoom in on a classic spot-the-difference.
- Here’s what to look for: the small dog in front of the woman on the right is missing in one version, the umbrella switches between red and blue, a little white boat vanishes from the upper left, a small girl disappears from beside the forked tree, and the man lying down loses his wine glass.
Level 27
You’re spelling out a composer’s name by flipping tiles in order. Get it wrong and it resets. The composer is Mozart, and the tiles land in this order: R H T M A B C O Z.
Level 28
The code’s all about tires. Drag the ones on the counter aside to reveal a color pattern: Blue, Green, Red. Grab the crowbar by the door and pry open the bus’s side panel to find one more hidden tire, a green one. Count them up: 3 blue, 4 red, 6 green. The code is 364.
Level 29
Grab the electrical tape from the table, the mop head off the floor, and the mop handle by the sink, then combine the mop pieces. Open the long desk drawer for a pipe wrench and use it to tighten the bolts on the pipe up top. Mop up the puddle, tape down the loose wires, and flip the power panel back on.
Level 30
Four creatures cycle through on a little screen: a snake, a frog, a rhino, and a whale. Use the arrows to line them up by size, smallest to largest, matching the circles on the left. Correct order, top to bottom: Frog, Rhino, Snake, Whale.
Levels 31 to 40
Level 31
Five basketballs are scattered around, and you’ve got nine seconds to get every single one into the basket. It’s tight, but keep trying and you’ll get the timing down.
Level 32
Open the trash can for a scrap of paper, and the desk drawer for some glue. Click the white panel above the bed to zoom in, glue the paper down, then piece the torn scraps back into a full square. Each piece clicks into place once it’s positioned right. Once it’s whole, the door code appears. The code is 21825.
Level 33
Three boxes sit on the floor showing the Parthenon, the Colosseum, and the Great Pyramids. Scattered letters and symbols around the room belong to Greek, Latin, or Egyptian writing, sort them into the matching box. Get one wrong and you start over. Greek: ΔΣΨΩ. Latin: LFQD. Everything else goes with the hieroglyphs.
Level 34
Solve the equations on the board. I couldn’t find any official order for these, so I just went with the order they’re written in, which happens to line up with the first three Greek letters anyway. Alpha: 9×0 = 0. Beta: 0+2+6 = 8. Gamma: 2+2-2 = 2. The code is 082.
Level 35
Open the book on the desk and you’ll see two pages of flags. The dots up top tell you the color order: Green, Yellow, Pink, Red, White, Blue. Count the stripes of each color across all the flags to build your code. Green: 4, Yellow: 3, Pink: 0, Red: 8, White: 5, Blue: 5. The code is 430855.
Level 36
Grab the flyswatter by the door and take out all five flies. You need the swatter’s head right on top of the fly for it to actually land.
Level 37
Water the wilting plant with the can sitting by the white table, then count up the tulips by color in the order shown above the door. White: 6, Yellow: 5, Blue: 4, Pink: 7, Red: 5. The code is 65475.
Level 38
The door shows you a color order: yellow, red, blue, green. How many times you press each button matches the number of books of that color lying around. Press: yellow 4 times, red 4 times, blue 3 times, green 5 times.
Level 39
Click the clipboard on the counter and zoom in. It looks like a random jumble of Hs and Os at first, but squint and you’ll spot numbers spelled out using the Os. The code is 2951.
Level 40
Open the laptop for a round of Snake. Eat 15 apples without running into your own tail, steering with the arrow buttons on screen.
Levels 41 to 50
Level 41
There’s a board above the green backpack pairing foods with the country they’re known for.
| Food | Country |
|---|---|
| Taco | Mexico |
| Sushi | Japan |
| Pizza | Italy |
| Chocolate | Switzerland |
| Hamburger | USA |
| Noodles | China |
| Sausage | Germany |
| Cheese | France |
Level 42
- This one takes a few steps. Click one of the grey boxes with letters on it to see a symbol at the bottom.
- Click the yellow box to browse license plates and find the one carrying that same symbol.
- Head back and dial in the letters from that matching plate until the box pops open, revealing a paper with another symbol.
- Repeat the whole process for the second box. Once you’ve matched both symbols to plates, add their numbers together.
- The left box matches the ER plate; the right box matches the TY plate.
- Opening them up, the left box has a plus sign and the WC plate symbol, the right has the TY symbol again.
- TY is 2269, WC is 4896. Add them together for a code of 7165.
Level 43
Click the portrait to reveal nine scrambled pieces. Rotate a piece by clicking it, and drag them back into their correct spots to rebuild the picture.
Level 44
Grab the cleaning fluid from the floor left of the door and the cloth on the shovel to the right. Turn the red knob on the pipe, and check the paper wad by the shovel. Clean off the mirror with your fluid and cloth to reveal the math you need. Turning the knob gives you a = 6. The paper wad gives you B = 2. The mirror shows: a+B, a/B, a×B. 6+2 = 8, 6/2 = 3, 6×2 = 12. The code is 8312.
Level 45
Click the shield to bring up a set of rotating rings. Line up the middle two pieces by turning the outer ring, then rotate the middle ring to bring the outer piece into place too.
Level 46
There’s a box marked with a poison symbol on the ground. Only the venomous creatures belong in it: the cobra by the sidewalk, the scorpion on the bench, and the spider on the wall to the left.
Level 47
Click the record player and listen to what plays while four composers appear on screen, Beethoven, Bach, Tchaikovsky, and Mozart, left to right. Pick whichever one you think matches the music. Guess wrong and the track restarts. Correct answers, in order: Mozart, then Tchaikovsky, then Mozart again.
Level 48
- Collect blue dye from under the bed, red dye from under the desk, and yellow dye from the sink counter, plus a syringe from the trash can.
- Click the white box on the steps to zoom in on a set of vials. Pick a color, then click the vial you want to fill, mixing colors as needed (the syringe lets you undo a mistake).
- Use the already-filled vials as your guide. Going around the circle, the vials should read: purple, blue, green, yellow, orange, red, orange, yellow, green, blue. The code is 9371.
Level 49
Click the game board by the door and steer the soccer ball into the goal with the arrow buttons. Hold a button down longer for more speed. Fall into a hole and the board resets, so take it slow.
Level 50
There’s a chalkboard full of numbers with one missing spot marked by a question mark. Zoom in if you need to. The yellow section reads 9, 13, and 117, since 9×13+117 works out. The blue section reads 23, 4, and 92, since 23×4=92. So the missing number follows the same logic: what’s 8×15? The code is 120.
Levels 51 to 55
Level 51
Grab a balloon off the water faucet and another from the shelf above the red stool, plus the water on the stool to the right and the helium in the middle. Fill one balloon with water and the other with helium. Let the helium balloon rise to hit the ceiling button, and drop the water balloon down onto the floor button.
Level 52
Take the screwdriver from under the vent and open it up to find a control stick. Attach it to the yellow handle on the right. Drag the hook over the engine, hook it, then lift the engine clear off the pallet. Slide the pallet aside to reveal your key.
Level 53
- Drag the tulips aside to find a puzzle piece underneath. Do the same at the big plant on the right, the pink hanging plant on the left, and the base of the cherub statue.
- Bring all four pieces to the puzzle on the door and reassemble the picture, rotating pieces with a double click and moving them with a single click and placement. The image has to be right-side up for the door to unlock.
Level 54
Grab the cheese off the green chair, move the water cooler out of the way, and feed the mouse. It’ll leave behind a key. Slide the cooler back and use the key on the door.
Level 55
Click the chalkboard and drag symbols into place to balance the equation: 7+2=39-30.

Level 57
- Click the chest on the floor to bring up a rotating puzzle, click each piece to turn it until the pattern lines up.
- Inside is a crossbow. Grab the quiver from under the left desk and combine them, then shoot the rope holding up a hanging box.
- Take the mace from the knight and smash the box open, then grab the key inside for the door.
Level 58
- Grab the wrench from the sink and the red rust remover from the shelf above the chair.
- Spray the remover on the metal bar blocking the door, then loosen the bolts with the wrench.
- There’s a crowbar sitting on the pipe up top, click the screen and shake the mouse back and forth to knock it loose, then pick it up off the floor.
- Use it to pry away the wood blocking the door, and you’re through.
Level 59
Three empty jars are scattered around the room, one on the table, one by the pedestal, one near the door. Mix dye by dragging the filled jars on the shelf into the empty ones to make green, orange, and purple, then set each finished jar on the shelf spot marked with a matching paint splatter.
Level 60
- Grab the record from behind the green chair and set it on the turntable.
- Click the turntable and watch numbers fly up and fade near the ceiling, each one lands in a different spot before disappearing.
- There are five of them. First number, a 2, lands second from the left. Second number, a 7, lands second from the right.
- Third, a 5, lands on the far right. Fourth, an 8, lands on the far left. Last, a 4, lands dead center. Reading left to right gives you 82475.
Levels 61 to 65
Level 61
The pattern above the door tells you to go largest to smallest, referring to the woodpeckers around the room. Count how many times each one pecks, starting with the biggest. The one on the tree (largest) pecks 5 times. The one on the bench pecks 3. The one on the log by the building pecks 4. The smallest, on the hanging log, pecks 2. The code is 5342.
Level 62
Click the basketball on the floor and it starts rolling, clicking left or right of it sends it that direction. Keep it sitting in the blue zone by the door until the bar fills up green.
Level 63
- Open the cabinet by the stool for a screwdriver, then use it on the panel marked ERROR.
- Zoom in and you’ll see white numbers up top and colored totals at the bottom.
- Click the white numbers to cycle their color (white to green to red to blue) until each color group adds up to the matching total below. Make these green: 12, 13, 15, 8. Make these red: 23, 3, 1.
- Make these blue: 14, 21. Fix the panel with the screwdriver again to reveal four colored numbers.
- Check the paper on the pin board for the equation: (Red + Blue) × (Green ÷ Yellow). Red is 124, Blue is 43, Green is 66, Yellow is 22. (124+43) × (66÷22) = 167 × 3. The code is 501.
Level 64
Four quadrilaterals sit on the chalkboard alongside a 90 degree angle marker. Count the right angles in each shape, that’s your four digit code. The code is 0000.
Level 65
Click the globe on the left to see a combination and a red bar. Drag the globe as instructed, releasing the mouse after each step to lock it in (mess up and you restart). Clockwise once, counterclockwise three times, clockwise twice.
Levels 66 to 70
Level 66
Click the blackboard on the lower left to see six images: mushroom, grasshopper, hawk, toad, snake, grass. Arrange them into a food chain. The mushroom feeds the grass, which feeds the grasshopper, which feeds the toad, which feeds the snake, which feeds the hawk, which eventually feeds back into the mushroom. Fastest fix is swapping the grass with the hawk, then the grasshopper with the grass.
Level 67
Grab the fire extinguisher off the wall and put out the flames. Take the screwdriver from under the vent, the gas can from the shelf, and the metal gear from the counter. Fuel up the generator, remove its front plate with the screwdriver, then fit the gear into place. Rearrange the gears to connect the lower left to the upper right. Flip the switch once they’re set, and if it’s right, they’ll start turning, letting you hit the green button by the door.
Level 68
Grab the box cutter near the whiteboard and cut down the hanging CD, then pick up the disk that falls. Load it onto the laptop on the right. Grab a printer cartridge from under the printer and load it, then feed in paper from the desk. Note the four patterns drawn on the whiteboard, then open the laptop to recreate them by connecting dots in a single continuous line (numbering the dots 1 through 8 starting at the top). Star pattern: 2, 6, 1, 4, 8, 2. Lower left: 2, 4, 1, 6, 8, 5, 2. Upper right: 3, 2, 4, 3, 7, 6, 8, 7. Lower right: 4, 2, 1, 8, 2, 6, 8, 4, 6. Once all four are done, the printer spits out your code, 598.
Level 69
Click the pile of trash by the door, it’s actually broken lab flasks. Repair them and slot them into the right order (double click to rotate, drag to move), and they’ll snap into place once you’re close enough.
Level 70
Stack the books on the center tile from largest to smallest, one at a time, never placing a bigger book on a smaller one. It’s the classic Tower of Hanoi setup with three spots: left, middle, right. Here’s a sequence that works: M-L, R-M, L-R, M-R, L-M, R-L, R-M, L-M, R-L, M-L, M-R, L-R, M-L, R-M, R-L, M-L, M-R, L-M, L-R, M-R, L-M, R-L, R-M, L-M, L-R, M-R, M-L, R-L, M-R, L-M, L-R, M-R, L-M, R-M, R-L, M-L, R-M, L-R, L-M, R-M, R-L, M-L, M-R, L-R, M-L, R-M, R-L, M-L, R-M, L-R, L-M, R-M, L-R, M-L, M-R, L-R, L-M, R-M, R-L, M-L, R-M, L-R, L-M, R-M.
Levels 71 to 75
Level 71
- Grab the plunger under the sink and clear the drain, revealing a piece on the floor.
- Take the hammer from the shelf and crack open the wall to the right of the door (two hits should do it), grabbing the piece hidden inside.
- Grab the red bottle from the same shelf.
- Click the box on the desk to zoom in on a rusty plate covered in dotted patterns, then clean off the rust with your bottle.
- Place your pieces on the plate, and roman numerals will show you where each one belongs, based on matching the number of dots. Line them up correctly and the box opens with a key inside.
Level 72
The chalkboard lists a bunch of gods next to a picture of the Parthenon. Click the board to zoom in, grab the red chalk, and cross out every name that isn’t from Greek mythology. Get one wrong and it resets. Cross off: Thor, Neptune, Mars, Anubis, Jupiter, Seth, Pluto, Horus, Osiris.
Level 73
It’s a dark room lit only by a utility light and a candle. Drag the candle around to uncover cards showing Greek letters paired with numbers. Alpha is behind the canvas near the keypad, worth 6. Beta is on the pedestal near the vase, worth 3. Gamma is above the candle, worth 4. Delta is on the floor near alpha, worth 1. The code is 6341.
Level 74

| Water Polo | 32 |
| Football | 60 |
| Volleyball | Infinite |
Level 75
The blackboard reads Blue Bowl + White Bowl + Red Bowl = ? grams. Grab the blue bowl off the table, the white one off the bench, and the red one from the blue chair, then weigh each on the scale. Blue weighs 560g, White weighs 405000mg (which is 405g), and Red weighs 2kg (which is 2000g). Add them up. The code is 2965.
Levels 76 to 80
Level 76
Click the chalkboard and rearrange the numbers so every side of the shape adds up to 20. Click a number to grab it, then click where you want it placed. Starting at the top and working around, one solution is 2, 3, 7, 8, 6, 1, 5, 4, 9, though yours might land differently and still work.
Level 77
- Grab a paper from the top of the eye chart, one from beside the desk drawer, one from inside the trash can lid, and one from the paper towel dispenser.
- Click the blue monitor panel to see four heart rhythm patterns, and match them up in order using your jagged paper edges as a guide. If you grabbed the papers in that order, here’s your pattern.
- Press the top button 3 times, the second button once, the third button 3 times, and the bottom button once. The code is 2854.
Level 78
- Full disclosure, this one doesn’t quite add up logically, but here’s how to beat it anyway. The letters FV above the door mean count the fruits for the first digit and vegetables for the second.
- Don’t forget to shake the tree, there’s a pineapple hiding up there. You’ll spot an apple, pineapple, banana, pumpkin, pepper, pear, apricot, and an ear of corn.
- Technically almost everything here is a fruit botanically, so you’d expect 71. That’s wrong though, the actual answer is 53, so it seems like the pumpkin and pepper got counted as vegetables anyway. The code is 53.
Level 79
A scrambled portrait of Queen Elizabeth I sits to the left of the door. Piece it back together and the door will open.
Level 80
Four colored hands above the door tell you the order to enter numbers. Broken plate halves scattered around the room each hold half a digit, mentally piece them together by color. Red is 8, Blue is 5, Yellow is 3, Green is 2. The code is 8532.
Levels 81 to 85
Level 81
There’s a box marked with a backbone symbol. Only creatures with a spine belong inside: the snake by the door, the frog near the microscope, the rat under the desk, the bluebird on the corner desk, and the fish in the bowl.
Level 82
Grab the butterfly net off the chair and the board leaning near the banana tree pot. Smack the beehive with the board, then use the net to catch the seven bees that scatter (line the net up with each bee, or click the net then click the bee directly). Dump them onto the fly trap plant on the table, then grab the key it leaves behind.
Level 83
Grab the tire iron, the air hose from the shelf, and the patch kit. Hook the hose to the compressor, then pull the flat tire off the bus with the iron. Set it in front of the door, patch it up, and reinflate it with the compressor.
Bolt it back onto the bus and tighten the lug nuts, then the bus rolls out of the way. Flip the calendar over to reveal a pattern, then use it to open the grey box that was hiding behind the bus. Grab the key inside for the door.
Level 84
A display case to the right sorts instruments into four types: pick, drumsticks, horn, and bow. Count each type. Pick (guitars): 3. Drumsticks (drum, drum, cymbals): 3. Horn (piano stool horn, flute, trombone, trumpet): 4. Bow (violin, cello, cello): 3. The code is 3343.
Level 85
Grab the hammer and chisel from the bench, plus the garden shears between the bike and tree. Trim the bush by the door with the shears to reveal a taped-up pattern behind it.
Chisel open the big red mailbox (tap the chisel with the hammer), revealing six buttons, each showing its own pattern. Clicking a button cycles its color, match each one to the color of the food item closest to that part of the pattern on the paper. Get them all right and a key drops to the floor.
Levels 86 to 90
Level 86
There’s a sign reading H2SO4, sulfuric acid, and you need to actually make some. Grab the sulfur canister, the water vial from the stool, and the oxygen canister. Pour the water into the triangular vial on the left, that’s your H2O.
Add sulfur to the round flask, then oxygen once (making SO2), then oxygen again (making SO3). If you followed the steps right, the game combines everything automatically into H2SO4. Set that flask on the sign to finish.
Level 87
Four spinners above the door track colored books. Count them up, but shake the room first (click and rapidly move the mouse) to knock four extra books loose from the ceiling. Totals: Red 6, Yellow 5, Green 5, Blue 4. The code is 6554.
Level 88
Click to continue and let the clock run out. The code equals however much time is left when it stops. A basketball game runs four ten minute quarters. Add the fourth quarter’s full ten minutes to whatever’s left on the third quarter clock. The code is 1749.
Level 89
- Grab the lighter fluid off the top shelf and the hose under the chair.
- Connect the hose to the propane tank, then turn the tank on. Take the lighter from above the red valve and soak it in fluid, then use it to fire up the burner.
- Pull the fridge handle off the wall and attach it, opening the fridge to find a key frozen in ice. Set the ice block on the burner to melt it, then shut off the propane. Grab your key and open the door.
Level 90
Pull the disk from the green backpack and flip off the lights using the switch by the door. Load the disk into the laptop facing away from you, then lower the projection screen to reveal your code. The code is 6934.
Levels 91 to 95
Level 91
Click the chalkboard and rearrange the numbers so every line totals 18. Leave the 6 sitting in the middle and shuffle the rest around it, one working layout puts the numbers where each spoke balances out evenly.
Level 92
Grab the fuel from the ground and the matches by the door. Fuel up both lamps flanking the door, then light them with the matches. Once lit, they’ll display your code. The code is 9247.
Level 93
- Grab the red lens from the top diploma, the yellow lens from the plant, and the blue lens from the eye chart, then equip the glasses on the stool.
- Papers hidden around the room only show their numbers under specific lens colors, so you’ll be swapping lenses and moving the glasses around to hunt each one down. Blue lens on the right side reveals the blue number.
- Red and yellow together on the right reveal orange. Red alone on the left reveals red. Add blue to that red to get purple. Swap red for yellow to get green.
- Swap blue for nothing and you’ll find yellow last. Blue is 8, Orange is 7, Red is 9, Purple is 5, Green is 4, Yellow is 1.
- The computer screen shows an order of Purple, Yellow, Blue, Green, Orange, Red, but the arrows tell you to swap Purple with Green and Orange with Yellow. So the real order is Green, Orange, Blue, Purple, Yellow, Red. The code is 478519.
Level 94
Grab the drumsticks behind the green chair and click the record player to hear a tune. Repeat it on the drum kit, cymbals as 1, left drum as 2, right drum as 3. Miss a beat and you’re starting the whole thing over. The pattern is 2-1-2-3-1-1-2-3-3.
Level 95
Open the book on the teacher’s desk to see a moon, sun, and star next to a set of country flags. Count how many of each symbol show up across all the flags. Moons: 3. Suns: 4. Stars: 9. The code is 349.
Levels 96 to 100
Level 96
Grab the lock pick off the blue chair and use it on the padlock. A red bar bounces up and down, click the screen the instant it lines up with the brown mark. Each bar moves faster than the last, and one mistake resets everything. This one takes patience more than skill, keep at it and it clicks eventually.
Level 97
Count the brushes by color, using the paint splatters on the shelf as your guide. Blue: 3, Red: 4, Green: 3. The code is 343.
Level 98
There’s a green circle marked 8 and an orange one marked 5, next to a computer showing a first aid cross. Zoom in and connect the dots so that exactly 8 land outside the cross and 5 land inside. The only shape that pulls this off is an X.
Level 99
Zoom in on the labyrinth to the left and use the yellow arrow buttons to guide the ball from the snake all the way to the frog.
Level 100
Grab the bus keys from underneath the bus and use them on the side panel, knocking the toolbox loose. Count up how many of each tool appear on the objects shown above the door. Hammers: 6. Wrenches: 11. Screwdrivers: 8. The code is 6118.
And that’s all 100 doors. If you get stuck on any one of these for a while, you’re definitely not alone, some of these puzzles genuinely do not explain themselves well in-game. Good luck getting through the rest.
