40 Square Logic Puzzles

In this collection of 40 Square Puzzles, your challenge is to add additional digits to some of the cells so that the sum of numbers in each row and column equals 40.

The 30 Square Logic Puzzles I shared previously were a hit, so I thought we would up the difficulty and try to sum to 40 instead.

Instructions

Each 40 Square puzzle consists of a 3×3 or 4×4 square grid with numbers appearing in each square.

Add one additional digit to some of the cells so that the sum of numbers in each row and column of the square equals 40.

In the above example, the original top row of the square was 6, 2, 9 which sums to 17. If you look at the puzzle solution, you can see that the 2 needs to be changed to a 25. Now 6 + 25 + 9 = 40.

It’s quite easy to make any single row or column sum to 40. The challenge is to make EVERY single row and column sum to 40.
