About this app

Every room hides one suspect. Can you find them all? Welcome to Cluedoku — a pure logic puzzle that blends the rigorous reasoning of Sudoku with the thrill of detective deduction. No luck. No rush. Just logic. Every case can be cracked with reasoning alone. Your mission: work out where every suspect is hiding, and close the case. SIMPLE RULES, DEEP DEDUCTION ► One Suspect Per Room: The crime scene is divided into colored rooms. Exactly one suspect hides in each. ► They Never Stand Together: Suspects can't share a row, a column, or touch each other — not even diagonally. ► Deduce, Then Commit: Tap to mark a tile with an X, double-tap to place a suspect. Place one wrong and you lose a life — you get 3. Every move must be reasoned, not guessed. ► Stuck? Call your Informant to reveal a suspect, or use Deduction for a hint that shows you WHY — so you get sharper with every case. WHY DETECTIVES STAY ► Thousands of hand-crafted cases, from quick 4×4 warm-ups to brain-bending 10×10 mysteries ► Investigate scene after scene — from the Mansion to the Gas Station, every crime scene brings new cases to close ► Climb the Precinct leaderboard and prove you're the sharpest detective around ► Play offline anytime — perfect for the commute, the queue, or the coffee break ► Learn in under a minute. Master over a lifetime. If you love deduction games, sudoku, minesweeper, brain training, logic grid puzzles, or detective mysteries, this is your next case. Cluedoku doesn't hijack your attention with grinds or gimmicks. It earns its place on your phone with one thing: the quiet, satisfying click of a case coming together in your head. The suspects are hiding. Open your first case now — free.
