This is another one of those games that you'd laugh/point your finger at if you discovered your rummed-up mom playing it on her PC. But make no mistake: Cube may have all the earmarks of a casual game, but trust us, once it seeps into your PSP, it'll stay there longer than a case of genital warts. The object of the game: to guide a cube through 3-D levels to the shimmering EXIT at the end. Sounds simple enough, right? Bombs, special quicksand cubes, and directional switches complicate matters. Some suspect controls and camera issues occasionally sully what's otherwise a solid head-scratching experience. And some of those 135 or so levels can feel repetitive. But overall, this is a cheap (less than $20!) distraction that's entertaining enough to get you through a week's worth of jury duty.
