Every tile has four edges. Every edge carries a mark. Place them so that each pair of touching edges agrees, and the board is solved.
That is the whole rule. There is nothing else to learn, and no tutorial to sit through — the first puzzle is four tiles and teaches itself.
WHAT MAKES IT HARD
The rule is simple. The boards are not. A 3x3 grid has one answer and several convincing near-misses, and by the time the shapes reach 6x6 you are holding three constraints in your head at once and finding that the fourth undoes them.
Every level is hand-tuned. There is no generator quietly producing thousands of interchangeable boards — there are 26, each one built, solved and checked, and each one is a different idea.
HOW IT PLAYS
Lift a tile and drop it on another to swap them, or on an empty space to move it. Tap a tile to turn it a quarter. That is the entire control scheme, and it works the same on a phone on a train as it does anywhere else.
You are ranked on fewest moves, not fastest fingers. Time only breaks a tie. Undo costs you nothing but the move it removes.
THREE PACKS
Origin — eight levels, free, forever. Small boards, clean ideas.
Fracture — nine levels. Shaped boards with holes in them.
Atlas — nine levels. Large, dense, and genuinely difficult.
Origin is free and always will be. One payment unlocks Fracture and Atlas together — no subscription, no second purchase, no currency to top up.
COINS
Finish a level and you earn coins. Spend ten of them and one tile drops into its correct place and stays there.
It is not a cheat, and it does not keep you off the leaderboard. The moves the lock makes count towards your score exactly as if you had made them. What ten coins buy you is knowing WHERE a tile belongs — which is the puzzle — not a smaller number than you earned.
LEADERBOARD
Every level has a global board. There is no account, no sign-up and no email address. You are given a name — two words, drawn at random — and an animal, and you can change either whenever you like.
Scores are verified on the server by replaying your moves against the same board. An impossible solve does not get on the board.
You can turn posting off entirely and the game works exactly the same.
WHAT IT DOES NOT DO
No advertisements. No timers counting down. No lives, no energy, no waiting. No notifications asking you to come back. No sign-in. It does not need a connection to play — only to show you the global board.
