About Unium

Your task is to draw a line. A single line. How complex can that be?

Start with one tile and trace a line to the next, then the next. Each tile you pass over flips from black to white, or back again. Using only a single line, can you flip all the black tiles?

The simplest puzzle can have hundreds of solutions, and Unium features over 100 levels to solve your way through. Unlock harder puzzles by solving easier ones, learn what works and what doesn't, and solve puzzles in multiple ways to earn achievements. Even better, use the built-in level editor to create your own puzzles, and share them on Steam Workshop! Unium is a fantastic pick up and play puzzle game that can entertain for a minute or an hour.

One of them has you doing spaghetti loops like a Texas highway and made me want to cry. Other than that, good puzzles. Of all the games I’ve purchased solely for emoticons, this is the second I’ve comeback back to complete. This one actually has a black box in the point shop and a super cute group of mini white hearts. A cat face you could use as well. You do not need to hold the mouse button to maintain your place of where you have drawn already and honestly thank goodness  You can turn the music off, however the sound as you drag will still go off. It reminds me of a 90’s toy (plastic stick you flip) and didn’t really notice until towards the end. You may be able to turn that off too.  For completists: since I did leave this idle two hours for the emoticons, it should take you 4.5 hours or less to complete depending on your problem solving skills

[h1] Puzzle game where you flip da bip to flippy d too. Basically it's all about flipping tiles to make them all in one color. Not a big fan of this one. [/h1]

Unium, developed and published by Kittehface Software, is a minimalist puzzle game that transforms a single, simple idea into a surprisingly deep and meditative experience. The premise is elegantly straightforward: draw one continuous line that passes through and flips black tiles to white until the entire grid is cleared. At first glance, this sounds almost trivial—an exercise in tracing rather than thinking—but within minutes, the game reveals an intricate logic beneath its clean exterior. Every level becomes a compact riddle of geometry and foresight, where the key to success lies not in speed but in precision, experimentation, and spatial reasoning. Unium captures the beauty of simplicity in design, where the rules are easy to understand yet infinitely challenging to master. The game’s early stages ease players in with small, forgiving grids that can be solved through intuition alone. As you draw your first few lines, the satisfaction of flipping the last black tile and watching the board reset to white creates an immediate sense of calm accomplishment. But as the puzzles progress, the layouts grow larger, the paths more convoluted, and the solutions less obvious. You soon rea…
