Great game! Finally a good alternative to Words With Friends.

To everyone complaining about registration, it's literally just entering in your email/nickname so your friends know who to send game invites to. Quick and simple.

To everyone complaining about the in app purchases, you do realize game development takes a lot of time and money? God forbid you pay 99 cents to support the developer so they can continue to make games. Even if you can't afford that, you can play the game (which includes all of "the parts that make it fun") for free with occasional ads.
