I like this ink game that came with my tablet pc. It launches multicolour balls out and you have to draw lines to deflect the corect colour ball into the correct hole. If you get the wrong coulour in the wrong hole, then you lose a life. Multiple balls at a time as well with multiple colours and other obsticles as well.
Pretty fun. Called "InkBall": http://www.microsoft.com/windowsxp/u...3july15ib.mspx
of course the guide lines shown on the pics dont show up in game play, and it can go pretty fast!
