Bub and Bob launch their bust-able bubbles across both screens in this Nintendo DS edition of the arcade action-puzzle game. As in earlier versions of Bust-A-Move, the game is played on a static field with it's upper portion full of differently colored bubbles. The object of the game is to clear the playfield by launching additional, carefully aimed colored bubbles up into the mix from the bottom of the screen, so that three or more bubbles of the same color touch and disappear. Unique to the DS version of the title is the manner in which bubbles are launched. Franchise dinosaur characters Bub and Bob hold a touch-screen trampoline that shoots bubbles upward at a trajectory that accords to the distance and direction it is stretched with the stylus.
