Addicting game that challenges you to get better.
*Edit*
After posting just the above comment I started to read some more reviews where folks gave the game 1 star and wrote an entire book of complaints. Just wanted to say to those folks, get over it. This is a free game. I play this game maybe 5-7 hours a week. If you have that many issues with a free game maybe you shouldn't play games like I tell my 6 year old....
