Forget your COD, CSS and Half Life. Two of the worlds best games are free (as in beer) and run on most operating systems. Canabalt and Robot Unicorn Attack. Both require less than three keys to play.

Both are platformers that have the exact aim. Get as far as possible with out falling or running into something. Pretty simple right? You can really get addicted to these and end up spending hours attempting to get to the non existent end.

Canabalt

Canabalt is a pretty straight forward 2D platformer. A guy is trying to escape from something (I’m guessing killer aliens) and takes to the roof top. You can’t stop running, and your only control is jumping. Jump from building to building. Run off the edge – dead, run into a building – dead, run into alien spaceship parts – dead, run into boxes – slowed (which eventually leads to death). Some buildings decide to crumble underneath you. Points are gained by distance traveled.

x,z – Jump

Robot Unicorn Attack

Like Canabalt, this is a 2D platformer. You are a Robot Unicorn which has some pretty nifty features, Dash and Jump. Your job is to get as far as you can without running into a wall, star, or falling off the edge. Longer you go, the faster you get. Points are earn’t on distance traveled, stars destroyed (using the dash skill).

Now be warned. After 2 hours of playing this game. Looking away from my monitor resulted in the room spinning. Sound is required.
