What is a Square Search Puzzle?
A square search puzzle is a puzzle made of a rectangular grid where each cell of the grid is filled with a number. The goal of the puzzle is to identify 2×2 squares within the grid which sum to a target number.
Here’s an example of a 100 Square Search puzzle where the goal is to find exactly six 2×2 squares which sum to the number 100.
Puzzle Source
These 10-31 Integer Square Search Puzzles were created using a Python program that I coded with some assistance from my husband. I am currently taking Harvard’s CS50P Introduction to Python course, and I am excited to put my new baby coding skills to good use in order to create more logic puzzles for my classroom and yours!
I was inspired by a collection of square puzzles I found on a French website recently. These puzzles involved finding a 2×2 square which sums to 50 or 100. The PDF credits http://www.rvtki.org (now defunct) as the original source of the puzzles.
The Internet Archive shows that this website was once ran by Hervé Baudier. I could not find out much more than that. I also found an additional collection of this style of logic puzzle on another French website.
Since I already have another set of puzzles called 100 Square Puzzles, I decided to rename these “Square Search Puzzles.” The Halloween (10-31) spin for these puzzles is entirely my own doing.
If anyone knows more about the origin of these puzzles that I have only ever found mentioned on French websites, I would love to have that information so I can update this post!

Puzzle Solutions
Puzzle solutions are available on a password-protected solution page. I do not openly post the puzzle answer keys because one of my goals as a resource creator is to craft learning experiences for students that are non-google-able. I want teachers to be able to use these puzzles in their classrooms without the solutions being found easily on the Internet.
Please email me at sarah@mathequalslove.net for the password to the answer key database featuring all of my printable puzzles and math worksheets. I frequently have students emailing me for the answer key, so please specify in your email what school you teach at and what subjects you teach. If you do not provide these details, I will not be able to send you the password.
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, or as fun activities in their workplace. Just give me enough details so I know you are not a student looking for answers to the puzzle that was assigned as their homework!
