Are you one of those who were hooked on JezzBall that was out 20 years ago? Now there's a version for Android that's just like the original. Check it out on the market, just search for "JezzBall Classic". Here's a link if you want to look at it in your browser: https://market.android.com/details?id=air.com.winterdust.jezzballclassicdemo What you do in JezzBall is build walls while making sure they aren't hit by any of the Jezz atoms that are bouncing around. When 75% of the screen has been filled you move on to the next level. It's pretty addicting. Note that only the half that is hit gets destroyed. And you can deploy the finished half of the wall while the other half is still being built... This can be used to make advanced wallbuilding moves. Also the number of lives are reset on level change so it's ok to sacrifice lives sometimes (but of course that means less score).
