Deduction and mystery puzzles

Deduction puzzles hand you clues instead of a grid. Read what each witness, statement or failed attempt tells you, rule things out, and the one answer that survives is the solution.

These games are built so the clues are always enough: you never need to guess. Work out who was alone with the victim, which islanders always lie, or which code opens the vault, then check your reasoning against the hint when you want a nudge.

Manor Mystery

A body, a floor plan and a handful of guests. Place everyone so every clue holds; the killer is whoever was alone with the victim.

Liar's Isle

Every islander always tells the truth or always lies. Read what each one says, then prove who is truthful and who is a liar.

Vault Cracker

Can you crack the code? Read the failed attempts on the safe and deduce the one code they allow. Green dots and gold rings are your clues.

Deep Sonar

Sweep the sea for mines by pure deduction. Every board can be solved without guessing, and the sonar shape changes as you go.
