Dukesbox recently released a new version of their Tower Defense game, and is hosting an open cash tournament. It’s only $.70 to enter, and the top cash prize is currently at $40.00! There’s 2 weeks left to enter, so there’s enough time for you to practice and take a shot at making a top score.

In order to help you prepare for the tournament, Cashgamers has written up a Tower Defense Guide. Take a look, and feel free to ask any questions you have about Tower Defense — again, we’re here to help!
