ルールHow it works

Three small guarantees that make the game fair.

Safe first click

Mines are placed after your opening move, never under it or its neighbours.

Honest clock

The timer starts on the first reveal and stops the moment the last safe square opens.

Weekly reset

Ranks clear every Monday, so a good week is never out of reach.
