15th Prison Game Overview
15th Prison (file size: 3 GB), developed by Zettanium, is coming on 20 May, 2025. You’re trapped inside a massive prison filled with endless blocks, where some of the worst criminals are kept. Strange things have happened here, and now it’s your turn to find a way out — by reaching Block 15 and solving the mystery.
To escape, you need to pass through each block, one at a time. At every checkpoint, a guard gives you an envelope — don’t lose it. Pay close attention to your surrounding. If you see anything weird or wrong, turn back. But if everything looks normal, keep going. What’s real and what’s not becomes harder to tell as you move deeper into the prison.
Once you reach Block 15, you’ll find three doors. Each leads to a different puzzle and a different ending. Solve the puzzle to make your escape easier — but getting there is half the challenge. The whole game takes about 20 to 90 minutes to play, depending on how quickly you can figure things out. Good luck… you’ll need it.
