Detective Grid: Clue Puzzle
Murder Mystery Logic Puzzle
Free · Designed for iPad. Not verified for macOS.
Twenty suspects. One grid. Every card you turn over gives you a new clue.
Detective Grid is a logic puzzle in the shape of a murder mystery. Nobody is guilty until you can prove it — and every case has exactly one solution you can reach by reasoning alone. No luck, no guessing, no hidden information.
HOW IT PLAYS
• Tap a suspect, then mark them innocent or guilty
• Each solved card reveals its clue, which unlocks the next one
• Clues talk about rows, columns, neighbours, professions and each other
• Get it wrong and the mistake counter remembers
1,000 CASES
Case 1 is a two-minute warm-up. By case 900 you are chaining a dozen deductions before the first card falls. Difficulty rises gradually across the whole run, so there is always one more case just at the edge of comfortable.
• Play offline — everything is on your device
• Six languages: English, Turkish, German, French, Spanish, Japanese
• Hints and skips when a case really will not break
• Dark and light themes, sound you can turn off
• No account, no sign-up
If you like Sudoku, nonograms, Minesweeper or classic whodunit riddles, this sits right between them: the deduction of a logic grid with the cast of a detective story.
