By Editorial / July 31, 2026 / Walkthrough / 12 minutes of reading

In this Strange Case 1 Walkthrough, I explain all puzzle solutions. It is a game full of suspense, a story about a case known as Alchemist. An entity has defiled a grave and nobody knows the reason why. I play as a detective from first person viewpoint and a ghost mode that I really enjoyed. The special power takes me to the same world but different dimension that seems the upside down. I examine every object surrounding me because to conclude the story I must solve all three chapters: Machine, After Death, and Honey. The house I am in is suspicious. I can move side by side, tap the object to zoom in, and add items in a tray at the bottom of the screen.

Chapter 1 – Machine

  • Tap the calendar and remember the date 19 September. The day is Wednesday.
  • Move to the room on the right and click the arrow again to reach the room with the table and chair.
  • Collect the glass, perfume, and bottle from the table. Tap the photo to complete the mini-game and get the number 23 along with the images.
  • Return to the second room and inspect the locker inside the cupboard. Enter 2138 to unlock it and collect the key.
  • Visit the fourth room and use the key to unlock the drawer. Collect the item from inside.
  • Inspect the machine on the table and complete the Pipe Connect puzzle by connecting all the pipes. Once done, collect the jar beside the machine.
  • Check the gun poster on the wall and note the letters on the bullets. Return to the second room and arrange the books above the locker using the same letter order. This rewards me with a matchbox.
  • Connect the jar to the pipe coming out of the machine and place the green-colored item inside it.
  • Put the empty bottle below the jar and let the orange-colored liquid flow into it. Before doing that, light the fire beneath the jar. Finally, place the glass at the other end of the machine.
  • Once the process is complete, collect the green liquid and give it to the mysterious person at the window beside the cupboard in the second room. This unlocks a new ability called Ghost Vision, allowing me to see objects hidden in another dimension.
