Cluedoku: Detective Sudoku

There's been a murder in the sudoku grid, detective. Every suspect has an alibi. Almost every.

Cluedoku is a cosy 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
• Whoever ends up in the room with the victim is your murderer. Case closed

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, a bar with karaoke and billiards: every location has its own rooms, furniture and stories. A mansion and a farm come with Plus.

1000+ CASES, FROM EASY TO NIGHTMARE
A story campaign eases you in and daily cases keep you sharp. Hard cases are free, as many as you like, and so is one Expert case a day. Past that, Master has the hardest clues in the game, and Nightmare lays them over boards up to 12x12. 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
