The Good
It gets your mind to think very fast, as you have only a couple of seconds to decide where to put your gems. Also it kind of develops your reflexes, you have to put the metal to the pedal very fast on the higher levels.

The Bad
The music SUCKS. Its kind of old fashioned, some thing you'll find in an old folks home, sure its relaxing but it does get boring after a bit.

The Bottom Line
Its OK if you like the playing arcade games for free, have good reflexes and a fast thinker. If your not, why not give it a try and get better.
