How to play Clear Sum
- Look at the target numbers on the right of each row and below each column.
- Click any number cell to delete (dim) it. Click it again to restore it.
- Keep adjusting until every row and column’s remaining numbers add up to their target.
- When all targets are matched, the puzzle clears and you score. Try a harder grid!
Tips & strategy
- Start with zeros. A target of 0 means every cell in that line must be deleted — easy wins.
- Check rows and columns together. Deleting one cell changes both its row and column count.
- Work from the edges. Lines with only one or two cells are easiest to solve first.
- Use the hints. The number turns green when a line is solved — watch for it.
Clear Sum is a logic puzzle inspired by Sumplete-style number games. It’s designed for adults who enjoy Sudoku, KenKen, and number-bond challenges. Just for fun — not medical advice.
