So there's this game/app you can download for your iphone/android/tablet device that is pretty awesome.
You know the game Jems? Some may remember the more updated version, Bejeweled Blitz? Well in this game you get characters (Marvel characters, mostly Avengers as it is the "Siege"/"Dark Avengers" story plot), and each of them have power associated to different colored jewels, and you just play Bejeweled (for really old school folks, think Tetris... sorta... or Yoshi's Cookies), and by matching a certain amount of colors, you can use that power to attack your opponet! It's super addicting and surprisingly not horrible on battery life, but the temptation to actually spend real money on it is there, so be careful. It's a free app, don't pay for it, you're being ripped off.
