Try your hand at Flummoxagon, a fiendishly difficult geometric puzzle that just might leave you flummoxed. It’s made of colorful wooden hexagon pieces that fit together like a honeycomb. The set includes every shape you can make by joining up to five hexagons, 48 unique pieces in total.

Flummoxagon combines the spatial tiling of Pentominoes with the constraint-solving of Sudoku. Try to fit all the pieces into a honeycomb while following the color rule: no two pieces of the same color can touch.

There are thousands of possible solutions! In addition to the 13 gameboards that come with the puzzle, we release weekly new puzzles on this website. Scroll down to download this week's puzzles.
