Demo limitations keep this pattern-making puzzle game from becoming addictive. The trial version of Caxcade doesn't let you set options such as fast animation, full-screen mode, and untimed mode. Some people will find the gameplay too easy on the first levels, since you only need to make the right double once. Others might wish they could play the game without the 40-second time limitation so that they could learn how to play. You can get points automatically when the computer adds new tiles, which could be part of the strategy but mostly feels like cheesy scoring. On the positive side, the graphics and animation look good, and the sound effects and music work well. We especially liked the tile textures. We recommend Caxcade if you're looking for a new twist on logic puzzles.
