About this game

Something is spreading across the panel, one ring every turn, by a rule that never changes. You get three walls a turn and a budget that does not grow. Seal it off before it reaches the edge.

There is no timer and nothing moves while you think. The whole game is the arithmetic: the front adds a ring every turn, and you add three walls. Work out where the gap will be three turns from now, and be standing there.

FIFTY LEVELS
From open ground with room to spare to boards where the budget is exactly the number of walls a perfect line needs. Every level is checked before release by replaying a winning line through the game's own rules, so a level that cannot be sealed never reaches you.

NEVER UNFAIR
No randomness during play, nothing hidden. The same moves always produce the same board. You are racing a rule, not a dice roll.

ONE PAYMENT, NOT A SUBSCRIPTION
The unlock removes every ad, makes the rewind free and instant, and plays the whole campaign with no connection at all. It is not a subscription: nothing renews, and there is nothing to cancel.

Nine languages. No account, no sign-up, no servers. Your progress stays on your device.
