"one of the more striking budget games we've encountered..." -'

"In one word, simply addictive." -

"...yet another interesting suggestion of how Apple’s touchscreens continue to inspire developers to come up with new gameplay ideas" -


Petri. Simple to play. Impossible to master.

The screen is filled with moving colors. Drag your finger to erase the color underneath. Double tap the screen to change the color to something else.

Try to make the screen whatever color is at the bottom.

Fun and Simple

This game is a pretty decent pick and play game. The controls are a little confusing at the beginning but once you get the hang of it... You'll get going at it. The game however needs a colorblind mode. Possibly introduce a mode where you use shapes or objects instead of just colors. Also, an icon change is foreseeable. BUY IT!

Great. Buy it.

This game is fun and addicting. It's good if you have a few minutes and need something to play. It's definitely worth $1. Anyone who has an iPod touch or iPhone should get this. Also, if you're a hippie you'll love this.

Oooooh the colors

Fun game with a decent learning curve. Once you get how it works, you'll enjoy the addictive fun! Highly recommended for those on hallucinogens! Totally worth the low price.
