Three logic games, one sprint a day. Every puzzle has exactly one solution and never needs guessing.
Daily puzzles are timed: the clock starts the moment the board appears and stops when it’s solved — no hints, no checks, one attempt per day. Practice mode is untimed with the full toolkit. Rules live behind the ? button in every game.
This is how you’ll appear on the leaderboards. No password, no email — your identity is saved on this device.
