According to the latest issue of Famitsu, Taito is developing a new installment of its Bust-A-Move puzzle series for the PSP. The game is titled Ultra Puzzle Bobble Pocket, and is slated for release on March 23. Ultra Puzzle Bobble Pocket keeps the traditional rules of the series while spicing up the gameplay with 16 different puzzle modes. The player is required to connect three bubbles of the same color in order to erase them from the screen. The puzzle modes in Ultra Puzzle Bobble Pocket include Blind Puzzle, where the colors of the bubbles on the screen are hidden with symbols, and See-Saw, where the screen tilts and sways if there are too many pieces on one side. As expected, players can challenge one another by using the PSP's ad hoc connection.
