Trap!

Heres a game I was completely addicted to. Trap is the name and what you are supposed to do is trap those floating balls using lines that go end to end. If any ball meets any unfinished line, then you lose a life. There are various bonuses, special balls and stuff to keep you occupied for a long long time. It does not seem so great when you start, but as you play, like any good game, it is supremely addictive.
