Eclipse in 60 seconds
Suns and moons in balance. Never three in a row.
The rules, in full
- Every cell holds a sun or a moon.
- Each row and each column holds equally many suns and moons.
- Never three identical symbols in a row or column.
- "=" joins two cells that match; "×" joins two that differ.
How Eclipse works
Fill the grid with suns and moons. Each row and each column ends up with equal numbers of both, and you can never put three of the same symbol in a line. The small "=" and "×" markers between cells tell you where two cells must match, and where they must differ.
