1. A nice Puzzle Bubble clone XBubble is a Puzzle Bubble / Bust-A-Move clone. Your goal is to remove all the bubbles from the game board. To do this you must aim and shoot bubbles. When you manage to match 3 or more bubbles of the same color, they burst and disappear. All bubbles which hang free now, will fall down and disappear, too. xbubble features single player mode, two player mode and player vs. computer (five difficulty levels of the AI) and has nice graphics, but no sound.
