Solstice

Fill every cell with a sun or a moon so that each row and each column contains an equal number of suns and moons.

No more than two of the same symbol may sit next to each other — three suns or three moons in a row, horizontally or vertically, is never allowed.

Tap a cell to cycle it: blank → sun → moon → blank. Bold, filled cells are locked givens and can't be changed.

Cells that break a rule are outlined and tinted so you can spot the mistake immediately.

Hint reveals one correct cell but counts against your score. Undo/Redo step through your move history.

Practice mode lets you pick a 6×6 or 8×8 board and any difficulty. The daily puzzle is an 8×8 board everyone plays together.
