Xpandaballs was Craig Caldwell’s puzzle game for iPhone and iPod touch. The July 6, 2009 listing describes firing balls into a play area, where a stopped ball expands to occupy space.
The next shot inherits the previous board
The central problem is room. A shot changes the area available to future shots, and a ball returning to the boundary costs a life. The original rules gave the player three lives. Clearing a ball is therefore also a way to preserve a useful route for the next move.
Five advertised ball types altered that decision. Normal balls supplied the baseline; speed balls moved faster; power balls could destroy another ball with one hit; black balls were harder to remove and worth more; golden balls could bounce from the boundary. The source also highlighted combinations that increased the score.
The historical feature list included three difficulty levels, resumed games, sound and music options, and global leaderboards. The local puzzle rules and the online score service are separate parts of the product; a surviving installation would not by itself prove the leaderboard still responds.
Current playability is unverified and no score was recorded for this article. This overview preserves the game’s distinctive space-management rules without repeating promotional claims about how addictive it was.
