4×4 Binary Logic Puzzles
You’ll need to keep your 0s and 1s straight while solving these 4×4 binary logic puzzles.

What is a Binary Logic Puzzle?
A binary logic puzzle is a puzzle with a rectangular grid that is partially filled with 0s and 1s. The puzzle solver must fill in the missing squares with 0s or 1s so that three rules hold true:
- Each row and each column has an equal number of 0s and 1s.
- No more than two digits in a row or column can be identical. (You can’t have three or more 0s or 1s together.)
- Each row is unique. Each column is unique.
These binary logic puzzles are also published under these names: Binairo, Binary Puzzle, Takuzu, and Tohu wa Vohu.
Here is a sample binary logic puzzle and solution to help you understand the rules.

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!
