Color Tap is a simple matching game with a slight twist -- the tiles consist of the names of colors that are written in different colors. It's a deceptively simple concept that ends up using more brain power than you'd think.

Speaking of which, women will find the timed game easier than men due to the way their brains are wired -- there are any number of studies demonstrating that, and it was certainly borne out in beta testing. Sorry guys, maybe next lifetime.

There is both a timed mode and a relaxation mode.
