About the game

Number Sums hands you a grid of digits and a set of target totals. Rows, columns and colored regions each carry a clue, and you circle the numbers that add up to it. Numbers you don't need get erased.

Every level has exactly one solution, so one lucky guess won't hold up. A circle that fixes a row can break a region, and that is where the thinking happens. Boards start at 3x3 and grow to 10x10.

How to play

• Circle the numbers that add up to the clue beside each row and column and inside each colored region.
• Use the toggle to switch between circling a number and erasing one you don't need.
• Make all rows, columns and regions work at once. Each level has only one solution.
