The game

Detective Grid is a deduction puzzle: twenty suspects in a grid, each holding one clue, and a single provable answer to the question of who is guilty. It is built for people who like being sure rather than lucky.

How the puzzles are made

Every case is generated by our own engine and then checked by an independent verifier that reads the printed clue text, rebuilds the rule behind it and replays the puzzle from scratch. A case ships only if it has exactly one solution and can be solved by forced deductions from the first open card onwards.

Languages

The game is available in English, Turkish, German, French and Spanish. The clues are not translated from one another — each language is written from the underlying logic, so every version says exactly the same thing.
