The Tic Tac Toe Challenge Puzzle asks “Can you place six X’s on a Tic Tac Toe board without making three-in-a-row in any direction?”
I ran across this puzzle several years ago. I typed it up along with a few other puzzles, and I named the file “Brain Teasers.” Then, I promptly forgot about the puzzle and file. I ran across the file yesterday while organizing my puzzles folder.
I originally typed up this tic tac toe challenge puzzle with the intention of using it on my puzzle table with laminated x pieces for students to place on the tic tac toe grid.
Once COVID becomes something that we can read about in a history book, I will likely end up printing off this puzzle and laminating the pieces. But, since it’s 2021, I decided to take this puzzle and make a few digital versions to share.

Jumbo Magnetic Version of Tic Tac Toe Challenge
I decided this would make a great magnetic puzzle for my dry erase board if I made the pieces JUMBO sized. I was right! Students loved it. Some students even tried using it to play regular games of tic tac toe by having one student use a dry erase marker to draw the O’s.
I intentionally do not share solutions to the puzzles I feature on my website because I strive to provide learning experiences for my students that are not 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 firstname.lastname@example.org with information about what you teach and where you teach. I will be happy to forward an answer key to you.
