Sunfleck

A new logic puzzle every day. Everyone in the world gets the same board, so you can compare your solve with anyone. Place one light in every coloured region so that: • exactly one light sits in each row • exactly one light sits in each column • no two lights ever touch — not even diagonally That's the whole game. There are no words to read and no trivia to know, so it plays the same in any language. EVERY PUZZLE IS FAIR Each daily board is verified before it ships: it has exactly one solution, and that solution is always reachable by pure logic. You will never have to guess and backtrack. BUILT TO BE PLAYED BY EVERYONE Colour is never the only signal — every region carries its own distinct shape, so the board is fully playable with any form of colour blindness. Full VoiceOver support throughout. SHARE WITHOUT SPOILING One tap turns your solve into a small grid you can paste into any chat. It shows how your solve went — never the answer. QUIET BY DESIGN One puzzle a day, about two minutes. No account. No sign-up. Works completely offline — nothing you do here ever leaves your phone. Keep your streak going.
