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.

Puzzle Solutions
I intentionally do not make answers to the printable puzzles and math activities I share on my blog available online because I strive to provide learning experiences for my students that are non-google-able. I would like other teachers to be able to use these puzzles in their classrooms as well without the solutions being easily found on the Internet.
However, I do recognize that us teachers are busy people and sometimes need to quickly reference an answer key to see if a student has solved a puzzle correctly or to see if they have interpreted the instructions properly.
If you are a teacher who is using these puzzles in your classroom, please send me an email at sarah@mathequalslove.net with information about what you teach and where you teach. I will be happy to forward an answer key to you.
Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, as fun activities in their workplace, or as a birthday party escape room.
