Tango puzzle rules: how to play sun and moon

Fill the 6×6 grid with suns and moons so every row and column holds exactly three of each.

1. Each row and column must contain three suns and three moons.
2. No more than two of the same symbol can sit next to each other in a row or column.
3. Cells joined by = must hold the same symbol.
4. Cells joined by × must hold opposite symbols.

• Tap a cell to cycle it: empty, sun, moon, empty.
• Long-press a cell to clear it instantly.
• Undo reverses your last placement, as often as you like.
• Reset clears every cell you placed and starts the board over.

Because three alike can never touch, two neighbors with the same symbol force the opposite symbol on both sides of them. And when two equal symbols have one gap between them, the gap must hold the other symbol.
