Rubik's World

For puzzle fans, this is definitely an experience worth having. The puzzle modes have 32 to 44 levels each, many of them quite difficult, and "Guide" mode in particular is a whole lot of fun. However, there's no point in beating the same level twice, and the "Create" and "Compose" modes aren't captivating enough to add much replayability, so this is a game to rent, not buy.
