Can you use logic to correctly place the pi symbols in these pi battle logic puzzles?
These pi logic puzzles are the perfect activity for pi day or just for a fun activity for your math class or math club!
Instructions
Place pi symbols in the grids so that each row, each column, and each region contains exactly one pi symbol. Additionally, pi symbols may not touch one another either horizontally, vertically, or diagonally.
The grid sizes range from 5×5 squares to 12×12 squares. The smaller grids are substantially easer to solve than the larger grids.
Origin of Puzzle
These pi battle puzzles are a fun seasonal variation on Star Battle puzzles which were introduced in 2003 at the World Puzzle Championship by Hans Eendebak.
Jim Bumgardner has been providing a harder version of these puzzles involving placing two stars in each row, colum, and diagonal to the New York Times under the name “Two Not Touch.”

Printing Options
You can download these 16 pi battle logic puzzles in two different formats: one puzzle per page or multiple puzzles per page.
I recommend using the one puzzle per page option if you only want to give students a single puzzle to tackle or if you would like students to solve the puzzle in a dry erase pocket.
If you want to challenge your students with a variety of different puzzle sizes, I would print the 3 page packet of pi battle puzzles with multiple puzzles per page.

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.
