Diatom is an Oddly Satisfying hyper casual game of color matching. And best of all, it's FREE!

To play, simply rotate the circles to line up matching colors, then swipe across them to clear the segments and earn points. Lining up and swiping four matching segments will clear ALL segments of that color from the board.

Diatom has four different modes from which to choose. Race against the clock in 60 Seconds, use your best strategies in 30 Moves, combine speed and smarts in Rewind, or chill out with Infinite. As you play, you'll bank the segments you've cleared to redeem them later for Assists.

Earn up to 30 achievements and share them on social media.


- 60 Seconds: Clear as many segments as you can in one minute
- 30 Moves: No time limit, but you only can only swipe 30 times
- Rewind: Start with 45 seconds, but you can put seconds back on the clock by clearing segments
- Infinite: Unlimited time and swipes! A great way to clear your mind and relax
