I have to admit, when my blogger buddy Greg from MobileCrunch told me he had an iPhone game that was based on a single button that lights up every now and again, I was skeptical. But, I figured I owed it to him to check out the game – hell, it’s free. But, I’m glad I did. Button for iPhone is expectedly simple, but that’s also what makes it a great little game.

I actually downloaded the game and gave it a shot. Button isn’t like most other games that require your full attention. It’s actually intended to be a little mental distraction that you can play while doing other tasks – blogging, for instance.

“Whether the player is building a spreadsheet or typing their next blog post, Button helps to keep them focused by giving their brain that little tickle it needs every once in a while. Simply by playing a game, you might be able to keep your mind on your work and your eyes off the ceiling.”

The button lights up and you tap it. Everytime you hit the button, you collect BTUs (Button Thermal Units). BTUs are like points. Simple.

You get to play against Button players around the world in real-time. And, you can band together in groups with other Button players around the world. Mostly, the game is cool because it’s actually a helpful distraction.

Like I said, it’s a fun little distraction. It might make you more productive, or it might turn you into a degenerate Button addict. Either way, it’s free on the AppStore.
