How to play Sun & Moon
Rules
- Fill every tile with a sun or a moon. Each puzzle has exactly one answer.
- Every row and every column has as many suns as moons.
- Never three of the same in a row, across or down.
Controls
- Pick Sun or Moon below, then tap tiles. Tap a tile again to clear it. Tiles with a dot are given and fixed.
Later on
- Signs (from level 10): = means the two tiles match, × means they are opposite.
- No twins (from level 18): no two rows, and no two columns, may be identical.
You have 3 lives: a wrong symbol costs one. Hints show the next logical step and explain why.
