Our take on Unium

Unium replaces the usual fixed-answer puzzle structure with routes that can have hundreds of valid solutions. Its built-in editor also extends the standard level set with player-created puzzles shared through Steam Workshop.

What is Unium?

Unium is a tile puzzle based on drawing one continuous line.

Start from one tile and trace the line to the next; every tile crossed changes from black to white or from white to black. The goal is to flip all the black tiles. The game contains over 100 levels, and some puzzles have hundreds of possible solutions. Solving easier puzzles opens harder ones. Completing puzzles in multiple ways can earn achievements. A built-in level editor lets players create puzzles and share them through Steam Workshop. The game supports short or extended play sessions, with enough content for a minute or an hour of play.
