Touch Em

Play Em has created a good variation on the standard tile matching type game. Touch Em is a well done game that varies from the usual in some interesting ways. While this is not the cheapest tile matching game, it does provide multiple game play methods and replay value that make it worth it.

Play modes include Score Attack, Time Attack, and Top Score. If you wish you can send in your scores to their server to be displayed in the online high scores list. Always a nice touch.

Some of the unique options are the ability to keep a match going with disconnected pieces for extra time. Hard for me to explain, but the included tutorial does a good job of it.

Here's a little movie showing the gameplay, animation, etc.

If you are looking for a new, good puzzle game, this is a good option. While it's not the most unique game in the world, it is very well done and provides a good amount of variation and replay value for $4.
