See It in Action
Click once for ✕ (no star here), click again for ★ — one star per row, column, and region
How to Play
- Find rows, columns, or regions with only two remaining available cells — stars must go there
- After placing two stars in a row or column, eliminate all other cells in that line
- When a star is placed, mark all 8 surrounding cells as unavailable (no-star)
- Work region by region: placing a region's stars eliminates options from its rows and columns
Pro Tips
Regions with few cells and those cells forced into narrow rows/columns are the easiest starting points
Every time you place a star, immediately cross out its entire row, column, and all 8 adjacent cells
Think about where a region's stars must fall based on which rows the region occupies
