Quiet Phases

Fill each grid with full moons and crescents — balanced, never three in a row. A fresh daily puzzle and unlimited practice. No ads, no tracking.

Quiet Phases — A daily logic puzzle in moon phases. Fill the grid with full moons and crescents under three simple rules.

Every row and column ends with three full moons and three crescents. Three of the same phase in a row or column is never allowed. An = joins two cells that match; an × joins two that differ.

There is always one logical solution, and you never have to guess.
