Knaves & Knights

Knights always tell the truth, knaves always lie — read their statements to work out who is which.

How to play

On this island, every knight tells the truth and every knave lies. Each islander makes a statement about the others' types, and from the web of claims you must deduce every islander's type and uncover a hidden fact. Harder rounds add normals, who may say either, making the deduction tougher. Mark each islander once the logic forces it.

• Read each islander's statement
• Assume a type and test it against the claims for contradictions
• Deduce every islander as a knight or knave
• Solve the hidden fact the puzzle hinges on

Controls

• Desktop: click each islander to set your verdict
• Phone & tablet: tap islanders to assign their type — fully touch-driven

Game modes

• Daily: the same islanders for everyone each day
• Practice: a fresh puzzle every run
• Easy, Medium and Hard add more islanders and the unpredictable normals

Tips & strategy

• Test a statement both ways — what follows if its speaker is lying versus telling the truth
• Look for self-referential claims; they often pin a type immediately
• Chain forced deductions: one settled islander usually cracks the next
