## What is Sun & Moon?

Sun & Moon is a calm logic puzzle you can solve in a few minutes a day.

Fill every cell of a 6×6 grid with a sun or a moon, following three simple rules:
• Each row and column has three suns and three moons.
• No more than two of the same symbol in a row, across or down.
• Cells joined by = must match; cells joined by × must be different.

Every puzzle has exactly one solution and can be solved by logic alone — no guessing needed.
