My first game for Windows Phone 7 is released and available in the AppStore. It can be found in the Games category under Board & Classic.
What is Chain Reaction? It's a strategic turn-based board game in which you must capture all your opponent's blocks. Blocks will explode when they are full and take over adjacent blocks. This can cause a chain reaction.
Because Microsoft only allows you to submit 5 free apps, this is a paid application. However, you can play it for free in Trial Mode!
The trial version lets you play the small field. The full version can also play the medium and large field.
