Windows Phone 7 users are often far behind when it comes to games on their phones. While we do have Xbox live and several games for it, we are often far behind the android market with games like Draw Something or Words with Friends. However, there is some relief for the WP7 users. Recently added to the marketplace is the Free game, Taptitude.Taptitude was created by Four Brothers Studios and features over 50 games with a constantly updated library with new games constantly being added. Taptitude is also free and all of the games that I have played so far have been great time killers. Games like Coin Miner 
(my personal favorite), are very well created and very easy to play as the only requirement is, you have to be able to tap on the screen in the direction that you want to go.
With other games like Draw A Star, where you have to draw a star as perfectly as you can to achieve the highest score and the most stars, Taptitude has a variety of games to keep every player engaged in the application.
Overall, Taptitude is one of the best WP7 apps that I have found on the market to date. Did I mention, its free?
