About

Prepare for a high-stakes mental workout in Number Sums, where math meets logic in a clean, minimalist arena. This isn't just basic addition—it's a grid-based detective mission. Your goal is to look at the target numbers along the edges and circle the specific digits in the rows and columns that add up to those exact totals. One extra number and the whole column fails; one digit too few and the row remains unsolved. It’s a game of deduction and calculation that turns simple arithmetic into a thrilling puzzle of elimination. Can you balance the board and find the unique solution hidden in every grid?

Features

How to Play

1. Examine the target numbers displayed at the end of each row and at the bottom of each column.
2. Tap or click a number to circle it if you believe it is part of the sum for that row and column.
3. Toggle the mode to 'X' out numbers that you have logically deduced cannot be part of the final total.
4. Balance all rows and columns simultaneously so their internal sums match the target edge numbers to win the level.
