Imaginative levels and a clever variety of bubbles and blocks make for an intriguing GBA debut of the perennially popular Bust-a-Move series.

As with previous entries, you shoot variously colored bubbles from a bubble launcher at screen's bottom. Your goal is to break up masses of bubbles by clustering three or more identically colored bubbles before they drop below the line at the bottom of the screen. If you leave too many bubbles in play, the ceiling will start on a slow-motion collision course with your launcher.

Normal mode is the basic one-player mode. Training mode introduces Super Bust-a-Move's offbeat varieties of bubbles and blocks, including Mini Bubbles, Giant Bubbles and Reflection Blocks. You can shoot Mini Bubbles through narrow passages. Once lodged in place, they'll grow to normal size.

Classic mode features levels from previous Bust-a-Move games. CPU Battle pits you against the computer at normal or expert difficulty levels. Two players with two Game Paks, a GBA Game Link cable and two GBAs can bust each other in Versus mode.

Offbeat characters add personality to the game. The GBA's shoulder buttons provide excellent control.
