There’s a little matching game called Threes for iOS that has really blown up, and taken the place of Flappy Bird in the popular consciousness (although to a lesser extent). We reviewed Threes right here, and enjoyed it quite a bit. If you’re holding off on spending the $1.99 to buy Threes for iOS, you can play a browser version of the game here.
The browser version plays the same, but it lacks much of the charm and polish of the iOS game. So if you enjoy playing it in the browser, just imagine playing the full thing anywhere, with lots of bells and whistles.
