30 Square Logic Puzzles

In this collection of 30 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 30.

When I was typing up these puzzles, my five-year-old became very interested in what I was working on. I printed him a page of puzzles to try out. We did the first couple of puzzles together, and then he really surprised me by solving a few of the puzzles entirely on his own.

Instructions

Each 30 Square puzzle consists of a 3×3 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 30.

In the above example, the original top row of the square was 1, 1, 1 which sums to 3. If you look at the puzzle solution, you can see that the second one needs to be changed to a 19 and the third one needs to be changed to a 10. Now 1+19+10 = 30.

It’s quite easy to make any single row or column sum to 30. The challenge is to make EVERY single row and column sum to 30.
