HONNE: Knights & Knaves

"Ai says: Bob is a liar." Knights always tell the truth. Knaves always lie. From nothing but their statements, work out who is who. There is always exactly one answer. Guessing will not save you, and nothing is missing — every puzzle contains precisely the clues you need, and not one more. WHAT YOU GET - One shared puzzle every day, the same for everyone, everywhere - Three to seven characters, as many puzzles as you want - After you solve it, the full reasoning, one step at a time - Draft mode for tentative marks; a hint reveals one character when you stall - Five settings: villagers, angels and demons, a robot factory, a pirate ship, a courtroom - Records for solves, streaks, and your best time at each size WHAT MAKES IT DIFFERENT The explanations. Most puzzle apps tell you whether you were right. This one shows you why: "Suppose Ai were a knave — then statement 3 cannot hold. So Ai is a knight." If you solved it, that is your check. If you didn't, that is your way in. Every puzzle is built on your device, the moment you ask for it. Nothing is downloaded from a catalogue. Each one is assembled and then verified to have exactly one solution before it reaches you. You will never run out. WHO IT IS FOR - Anyone who likes sudoku or escape-room riddles and wants a different muscle - Three quiet minutes on a commute, in a queue, before sleep - Anyone who met Knights and Knaves years ago and never forgot it - Learners who want deductive reasoning shown, not just tested - Parents looking for something to think through with a child PRIVACY - No account - No network. Everything works in airplane mode - Your records stay on this device - No third-party advertising or analytics SDKs. None We did not want anything sitting between you and the puzzle.
