One of my favorite time killer games for BlackBerry, Catapult, just had a cool update. The objective is simply to fling your rock through the air, and see how far it will go. There are targets you can hit which increase your score, springboards on the ground that bounce you back up into the air with a burst of speed, and sandboxes that will bring your stone to an immediate halt. The update has added stars to catch which allow you to buy upgrades to luck, bounce, spring, and rubber. There were also some bug fixes and the addition of sound effects, if that's your thing. (If not you can turn them off.)
Catapult has a great UI with simple graphics and a really smooth feel. This game is compatible with BlackBerry 83xx, 85xx, 89xx, 9000, 93xx, 91xx, 95xx, 96xx, 9670, 97xx,and 9800 and costs just $.99.
