It looks better than the version found in your Game Room on the Xbox 360. You don't need to fear the controls because the virtual trackball gets the job done quite nicely. Everything you do on the phone verison carries over to the Xbox 360 Game Room side and vice versa. I'm looking forward to all of the upcoming GR titles on Windows Phone 7, it adds a neat dynamic to the Game Room experience and works seamlessly.
Amazing Great Good Decent Bad Terrible
Achievement difficulty: 3 out of 10
Time to complete full 200 Gamerscore points: 2 hours, a lot less if you have already done the three Golds on the Xbox 360 version of Game Room.
Worth $2.99? Yes
Tip: I personally believe it's easier to do the golds on the 360 side. Do that then load it up on your phone and the achievement will pop.
