About this game

Hex-a-Decimal is an automation puzzle game on a hexagon grid. Set up lines of conveyors, pausers, sensors, and various other components to get signals to where they need to go. It's a challenging game that anyone can pick up, but the question is: how far will YOUR puzzle solving skills take you?

Master the game's many puzzles and mechanics:

Hex-a-Decimal is a game full of challenging puzzles and complex emergent systems. As the levels progress, you'll learn to think in a whole new way as the game introduces and expands on easy to learn / hard to master mechanics.

Optimise your solutions:

Whether you're stuck on a later puzzle or have simply completed them all, levels in Hex-a-Decimal have lots of replayability. With three individual stats and a total score, you can go back to a level you completed and spend hours trying to optimise your solution.

Unleash your creativity through the built-in level editor:

Got an idea for a challenging new level? Make it yourself! Hex-a-Decimal comes with its own level editor, the same one which was used to make every level seen in the game, and countless more can be created using it.

    The Hex-a-Decimal demo is out now!

    This is my first time publishing stuff to Steam, so news might be slow and things might be rough around the edges as I get my bearings. Anyway, the demo is officially out! You can actually go to the store page and download the game, and I think that's pretty neat.Also, there are some features that really need to be added, such as indicators for when you've lost (whatever caused you to lose should flash, so when a 16 runs out, it flashes, or when an 8 is overpowered, it flashes) and saving/loading solutions.Other than that, the demo has everything you need, so get to it!
