If you've ever played Bust-a-Move then you'll love Frozen Bubble which is a hugely popular puzzle game on the Mac.
Frozen Bubble is a classic matching 3 game where you have to eliminate other bubbles by blasting them with the appropriate colors. Your cute penguin type character aims your shots using a turning wheel upon which your canon is placed. The further you progress, the lower the roof descends meaning you're under increasing pressure to obliterate the balls.
When you've managed to eliminate all the bubbles, you move onto the next stage. There really isn't much more to it than that. The soundtrack is very chilled out and a bit out of place but there's lots of cute sound effects and it gets increasingly addictive the more you play.
Frozen Bubble is an addictive little game that's simple enough for even kids to play. Give it a go and you'll see why it's become so popular.
