How to Play Yin-Yang
Color cells black or white so all black cells form one connected group and all white cells form another, with no 2×2 area being all the same color.
Try it now — Easy 8x8 →The Rules
- Color every cell black or white
- All black cells must form one single connected region
- All white cells must form one single connected region
- No 2×2 block of cells may be entirely the same color
Available in 3 sizes (6x6, 8x8, 10x10) and 3 difficulty levels (easy, normal, hard).
See It in Action
Color every cell black or white — both colors must each form a single connected region
How to Play
- Given (pre-colored) cells anchor the solution — extend each color region from those cells
- If coloring a cell one way would disconnect the opposite color's region, use the other color
- Prevent 2×2 monochromatic blocks as you place each cell
- Use both connectivity rules together: each decision affects both black and white connectivity
Pro Tips
The 2×2 rule is the most useful constraint — when three cells of the same color form an L, the fourth must be the other color
Think of both colors as two countries that must each be fully connected — neither can have isolated enclaves
Given cells of the same color close together help anchor connectivity — start extending from those clusters
