Numbers are boring (sorry, accountants). So this reinterpretation of Sudoku by Brass Monkey uses colored wooden balls instead. Includes 81 balls and a gamebook with hundreds of setups to solve with friends (or by yourself if you’re into that). Bonus: everything stores away into the box (that is also the game board), so it’s perfect for traveling.

• Features 81 painted ball pieces that nest into the holes of the included game board
• Perfect for traveling (or playing during mild earthquakes)
• Includes a gamebook with hundreds of puzzles to set up and solve alone or with friends
• Everything (including the chessboard) packs away into the display-worthy box
• Box measures 7.8 inch square
