This is a puzzle game featuring squares, circles, colors, original mechanics, sane difficulty curve, plot twists and occasionally annoying jokes.
You will learn the rules as you go, so jump right in!
If you want to play it on your mobile device, you can do so on mobile friendly http://gameaboutsquares.com. It's much brighter over there, by the way. Alternatively, the apps are available for all major mobile platforms.
NOTE: If the red square doesn't seem to be clickable, try different browser. That's an elusive bug. Sorry for the inconvenience.
