Each room hides a puzzle. Solve it. Open the next door.
Three wrong answers and the dungeon walls seal you in.
You fell at room 0.
The answer was:
The dungeon has no more secrets for you. For now.
Start AgainRiddleCrypt is a logic puzzle game wrapped in a dungeon adventure. Each "room" of the dungeon contains a single puzzle. Solve the puzzle to open the door to the next room. The deeper you descend, the harder the puzzles become — from gentle warm-ups in the early chambers to expert-tier reasoning in the depths.
Every wrong answer counts as one strike. After three strikes, the dungeon walls grind shut and your run ends. Your record — the deepest room you reached — is saved to the public leaderboard. You can start a new run any time, or spend a key to revive at the last room with one strike already used.
Four categories of puzzles, mixed randomly throughout your descent:
Difficulty starts gently at room 1 (puzzles a curious child could solve) and ramps to expert level at room 100, where each puzzle demands multi-step reasoning or specialized knowledge.
No. RiddleCrypt is fully playable without signup. Your run is saved automatically in your browser, so you can return to the same dungeon later. Your name on the leaderboard is auto-generated to keep you anonymous.
Keys 🗝 are the in-game currency. Spend one key for a hint when you're stuck, or one key to revive after running out of strikes.
