Sum Sweep

Sum Sweep is a calm logic puzzle about numbers. Every row and column shows a target sum. Erase the right numbers so that what is left adds up to each target. Every puzzle has exactly one solution, so you can always work it out by reasoning, never by guessing.

HOW TO PLAY
• Tap a number to erase it. Switch to Keep mode to circle the numbers you are sure about.
• When a row or column is finished, its target turns green.
• A wrong tap costs a heart. Lose all three and the puzzle is over.
• Stuck? Use the free hint, or watch a short video for more.
