If you're a Pocket PC user looking for a new time waster, do yourself a favor and check out Escape Velocity from ClickGamer.com.
This is a very addictive puzzle game that is cross between Tetris and Pipes. You tap on the pipes to rotate them in such an orientation that they can connect to other pipes. Once you have a line of pipes that connect the fuel pod to the rocket, they fall down like in Tetris. If you can connect enough fuel pods before time runs out, the rocket will blast off. Great sound effects and graphics make this game entertaining and fun. $9.95 isn't a bad price either!
