Kludoku is a murder-mystery logic puzzle: place every person on the crime-scene map using testimony alone, then accuse whoever was alone with the victim. Every case is generated with exactly one solution — no guessing is ever required.
Work testimonies like sudoku constraints: intersect what each statement allows, X-mark what it forbids, and pencil-note candidates. Every placement eliminates a full row and column — the board collapses fast once the first few suspects are fixed. In-game, tapping a testimony line highlights its squares; assist modes can gray illegal squares while you learn.
Stuck between two candidate squares? Right-click a suspect's face (hold on touch) to open a hypothesis branch: your guesses render dashed on top of the real board, parallel branches wait as mini portraits in square corners, and a refuted branch strikes the disproven pencil mark for you. Keep the branch that survives; the real board never moved.
Some cases warn that one suspect is the murderer's accomplice — and everything they say is false. Mark your suspect with the 🎭 toggle to render their statements inverted (the game rewrites each line to its logical opposite). Full technique in the accomplice guide.
