Sum Grid

How to play

Keep the right numbers so every row and column adds up to its target.

• Each row and column shows a target sum at its edge.
• Use the Keep tool to circle a number, or the Cross tool to remove it.
• The circled numbers in a line must add up to that line's target.
• A wrong mark costs a heart — you have 3.

Tips

• Start with lines whose target is very high or very low.
• A crossed-out number counts as zero.
• Hold a number to use the other tool (Keep/Cross) without switching.
• Add up a whole line, then cross out numbers equal to the amount it goes over the target.
