About 15th Prison

15th Prison is about finding an escape route through a prison with endless blocks, where notorious criminals are held and horrific events have taken place. You observe your surroundings and collect an envelope from the guard each time you pass through a block; the envelopes are important to your escape plan.

Find the way forward

Watch for anomalies. If you find one, turn back immediately; if you find none, keep moving forward. At block 15, you face three different doors, each with its own puzzles and ending. Solving the puzzle at the end makes your escape easier.

The playing time is 20–90 minutes.
