Cluedoku: Detective Sudoku

A murder mystery on a sudoku grid. Cluedoku is a cozy murdoku-style detective game where every puzzle is a crime to crack: read the clues, work out who was where, and unmask the murderer with pure logic.

🔍 A DETECTIVE LOGIC PUZZLE
Every clue card is a witness statement: "Emma was sitting on a chair", "Boris was beside the fireplace". Place the suspects sudoku-style, one per row and column, cross off the impossible and close the case. No guessing: every murder mystery has exactly one solution, reached by pure deduction.

🗓 A NEW CASE EVERY DAY
A fresh daily puzzle lands each morning. Solve the daily case, keep your streak alive and chase the perfect loupe rating. A few minutes of brain training with your morning coffee, or a long evening of detective work: you choose the pace.

🏘 INVESTIGATE THE WHOLE TOWN
Suburb homes, a corner shop, a cafe, an office: every location brings its own rooms, furniture and suspects. Study the crime scene, compare alibis and watch the mystery unravel cell by cell.

🧩 1000+ LOGIC PUZZLES, EASY TO EXPERT
A story campaign teaches the detective craft step by step, no experience with logic grid puzzles needed. Daily cases keep your brain sharp, while Hard and Expert sudoku grids up to 10x10 deliver a serious logic workout. New cases are added all the time, so the investigation never runs dry.

💡 HINTS THAT TEACH DEDUCTION
Smart hints show the next logical step instead of spoiling the answer. You learn real deduction techniques as you play: brain training that feels like a detective story, not homework.

⚔️ DUEL RIVAL DETECTIVES
Race another detective on the same case in ranked duels. Climb the leagues from Wood to Diamond, defend your rating season after season and prove your logic under pressure.

🤝 CO-OP MYSTERY SOLVING
Team up and crack a case together with a friend. Two detectives, one board, shared deduction.

🏆 TROPHIES, AVATARS AND STATS
Unlock 50+ achievements, customize your detective avatar and track your solve times, accuracy and streaks in detailed statistics.

NEW TO DEDUCTION GAMES?
Start with the campaign: the first cases introduce one clue type at a time, from simple alibis to tricky logic chains. In a few days you will read a crime scene like a seasoned detective.

SUDOKU PLAYER LOOKING FOR A TWIST?
If classic number puzzles feel routine, Cluedoku keeps the elegant row-and-column logic you love and swaps digits for suspects, alibis and motives. The same satisfying "aha", a brand-new mystery every time. And if the murdoku craze pulled you in, this is the same clue-driven whodunit formula, with a daily case, duels and co-op on top.
