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.
