If you think this looks fun, please consider buying or sharing it! We'd love to be able to work on it more. We have plans to implement an online version of the game. We also want to try to compute exactly how many possible solutions there are to the puzzle

Thanks!🙏

Here's a tutorial of how you play a simple scenario. The Flummoxagon comes with 13 game boards and we'll be posting more regularly online, so it's endless replayable

It turns from a tiling puzzle to a game like a Sudoku. The Flummoxagon is just a space within which these game boards can be played. You start with a given set of tiles and need to use the constraints of the color and shape find the unique solution. And it's very satisfying once it comes together.

This led us to the idea of a difficulty curve: many solutions is easy, in the middle it gets hard, but more constraints get easy again. If there's only 1 solution, your decisions are more forced. We could choose a subset of the puzzle that had 1 solution. These scenarios turned into the real puzzles

When testing, we realized this made the puzzle hard. Like REALLY hard. Like maybe impossible? This was interesting because the original puzzle was kinda easy (20-30 min). The Flummoxagon still has hundreds of thousands of solutions, but the increased constraints make it difficult to find even one

We decided to add colors to try and make it more compelling. It was visually more interested and introduced more ways to put it together that would feel meaningful. Like you could add a map coloring rule where no adjacent tiles have the same color.

We were originally making a tiling puzzle, similar to Pentaminoes, but with every polyhex from 1 to 5. The problem was

A. This wasn't very original
B. It had limited play value

Even though it has millions of solutions, it's hard to come up with compelling reasons to put it together more than once.

It’s already available for preorder. We’re just waiting to receive the playing cards from the printer

I don't see why they need an update. I haven't aged one bit, and my hairline is in the exact same location. You do have new glasses though
