I've had the free one installed for quite a while. Nice to see they're giving away the full version for free! This is a great little game for passing time while you're on the pooper.
Also, if you like this one, check out Harbor Master. Same concept, but with boats. Very well done.

I've had it on the iPhone since my 3G, and am happy to have it for free on the iPad now.
