Handy Entertainment has released a new game for Palm OS PDAs called Nuclear Ball.
"Rotating balls has never been so addictive. An utterly absorbing game of logic with completely refined gameplay. Plunge into the industrial atmosphere of test-tubes, sparkling wires, atoms and sudden chain reactions. Clear the logjam of atoms on your way to glory by matching colors together. Feel the sweat on your forehead, when one wrong stylus movement may lead to the big bang."
