Hexahedra

Hexahedra is an open-ended programming puzzle game about keeping a struggling cube factory running. You design factories, program devices to work together and ship cubes made to meet each customer's requirements. As you progress, you can earn a position at Hexahedra Inc., the galaxy's most prestigious cube fabricator, and investigate rumors that cubes are being used for sinister purposes.

Build and program

Factories use a grid-based command system for creating complex loops, while lasers and proximity sensors let you branch the logic flow. You can pull cubes apart and reassemble them, merge and paint them, teleport them, set them on fire or add payloads before shipping them to customers. Their uses include crates, musical instruments, octopus housing and sculptures, and some requests arrive on damp paper in strange ink.

Rewind and optimize

A timeline lets you rewind the factory to inspect its past state, replay steps and find bugs or ways to improve a solution's efficiency. You can compete with friends and players around the world to solve each puzzle with the quickest or simplest solution.

Create puzzles

The built-in level editor lets you make your own puzzles and share them with friends or through the Steam Workshop.

The cube conspiracy

Cubes are the galaxy's most important commodity, and some want to exploit that for their own gain. You can track down and infiltrate the conspiracy, then bring it down—or leave it in place and join the new rulers.
