Fantastic free iphone games, so good on so many levels. First, it’s fun to just smash things, sounds and animation and physics are really well done. Then it is great fun as a puzzle. Then even once you solve it, it’s challenging to figure out how to three-star each level. Most games are frustrating while you can’t do it. But in this one failing over and over is still fun. Then in most games once you’ve figured it out there’s no more challenge but this one never becomes automatic, always fun to do over. Kids love it, casual gamers love it, puzzle fans love it, I love it.
