The Flummoxagon

Summary

We’re excited to announce Flummoxagon, a new geometric puzzle game that might just leave you flummoxed. Imagine a mash-up of Pentominoes and Sudoku. Your goal is to fit all the pieces into the hexagon frame but there’s a twist, pieces of the same color can’t touch. It’s a fiendishly fun mix of Tetris-style block packing and logic-based constraint solving. The game ships with 13 gameboards, featuring puzzles from beginner to advanced, and new boards are added weekly to our website. You can buy Flummoxagon now in our shop for $45. For the first month, take 20% off with the coupon code FLUMMOX (ends 10/31/2025). How do you play? Flummoxagon is made up of 48 tiles representing every shape you can make by joining up to 5 hexagons. All the tiles fit into a hexagonal frame and they come in 4 colors. There are 12 pieces of each color and 54 hexagons of each color (except green since there are an odd number of hexagons in the grid). The challenge is to place every piece into the frame without letting two tiles of the same color touch. Now, there are hundreds of thousands of ways to do this; however, finding one on your own is nearly impossible (though let us know if you manage it!). Instead of an empty grid, to play the Flummoxagon, you start with a partially filled gameboard that only has one unique solution, just like a Sudoku. Each gameboard creates a challenging puzzle to solve. The puzzle ships with 13 of these gameboards of varying levels of difficulty, and we add new puzzles weekly on our website for endless challenges. How did we get here? Jules has been interested in these kinds of tiling patterns since before he worked at Nervous System. He built a solver for placing tiles on a grid which is a version of a problem called an “exact cover.” Instead of a puzzle, he used it to make patterns which he turned into cast vessels. When he started working here, he wanted to use it to make a puzzle, which he did for friends and family. The first version had no colors. There we...
