Wordament is a fun and addicting iOS game and it’s also the first iOS game to feature Xbox Live achievements (if you login via an Xbox Live / Windows Live account). It’s basically a boggle game but it’s unique in that there’s always a game going on. As soon as you open the app you can be thrown into a game in progress and finish out the round. You’ll get a score based on the words you find in the round and at the end of each round you’ll see a leaderboard showing you how you match up against everyone else who was playing that round.
There’s no waiting for games or waiting for your turn, it’s always on in a sense. This is what makes it addicting. You’ll be telling yourself “one more round” as you lay in bed and next thing you know an hour has passed.
I love that it has Xbox achievements and that it’s 100% free. Sure the achievements are only worth 5 gamerscore each, but it’s a nice addition. Let’s hope Microsoft brings more games to iOS soon.
