Cluedoku: Detective Sudoku
Daily murder mystery cases
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The witness statements all add up. What they add up to is standing in the same room as the body.
There's been a murder in the sudoku grid, detective. Every suspect has an alibi. Almost every.
Cluedoku is a cozy detective puzzle where classic sudoku logic meets a murder mystery. Read witness statements, cross off impossible cells and pin down the culprit. No guessing, ever: every case has exactly one solution, and you can reach it by pure deduction.
HOW A CASE WORKS
• Every clue card is a witness statement: "Emma was sitting on a chair", "Boris was beside the fireplace"
• Place each suspect in their row and column, sudoku-style
• Corner the last liar and close the case
A NEW CASE EVERY DAY
One fresh mystery lands daily. Solve it, keep your streak alive and chase the perfect loupe rating.
INVESTIGATE THE WHOLE TOWN
Suburb homes, a corner shop, a cafe, an office: every location has its own rooms, furniture and stories.
1000+ CASES, FROM EASY TO EXPERT
A story campaign eases you in, daily cases keep you sharp, and Hard and Expert modes on grids up to 10x10 will bend your brain. New cases are added all the time, and they work offline: solve on a plane, on the metro, anywhere.
HINTS THAT TEACH, NOT TELL
Stuck? Smart hints walk you through the next logical step instead of spoiling the answer, so you become a better detective with every case.
PLAY TOGETHER
• Ranked duels: race a rival detective on the same case
• Leagues: climb from Wood to Diamond, week by week
• Co-op: crack a case together with a friend

LOVE MURDER SUDOKU PUZZLES?
Cluedoku is an independent murder sudoku built for the phone. If you came here from murdoku-style puzzle books or from a daily logic grid, this is the same deduction with a new case every day, offline play, duels and co-op.
Grab your magnifying glass, detective. The town needs you.
Your league can warn you now: if a rival pushes you out of the promotion zone, your phone says so while there is still time to play. Plus a round of small fixes.
