Crime Sudoku: Mystery Puzzles

Every suspect belongs somewhere. Every clue reveals part of the mystery. Can you work out who was at the crime scene?

Crime Sudoku combines logic puzzles, deduction and detective mysteries on a grid. Read the clues, connect rooms and objects, and place each suspect where the evidence says they belong.

ONE SUSPECT PER ROW AND COLUMN
Each character occupies a different square. No two suspects can share a row or column. Use positional clues and relationships between characters to work out the complete arrangement.

REVEAL THE CULPRIT
Once every position satisfies the clues, the suspect at the crime scene reveals the answer. Eliminate possibilities and connect the evidence to solve the case.

FIVE DIFFICULTY LEVELS
Choose from very easy, easy, medium, hard and expert. Start with straightforward deductions and move on to cases that require longer chains of reasoning.

CHOOSE YOUR CASE
Pick the numbered puzzle you want to solve. Each case keeps the same board, clues and solution, so you can return to the same challenge.

ONE VERIFIED SOLUTION
Published cases are checked for a unique solution. Your challenge is to deduce each position from the available clues.

TIMES, MOVES AND RANKINGS
Explore rankings based on the difficulty of solved cases and records from the first valid completion.

Learn the rules with the tutorial, choose your first investigation and follow the clues. The culprit is somewhere on the grid.
