**How to play:**

You will see circles with random numbers appear in 4x4 or 5x5 grids.

The number in the square is the Sum of the corresponding row or column.

Based on the sum and the numbers in the row or column, hide the inappropriate numbers. To that end, the sum of the circles is retained by the number in the square of that row or column.

*Notice the relationship between the sum and the numbers in the row and column.*

Have fun!
