Bejeweled 2 continues PopCap's gem-matching game with four play modes, ten sci-fi backdrops, and new strategies to master. Once again players are challenged to create matches of three or more by swapping adjacent gems horizontally or vertically. Players advance levels and build their score until it is no longer possible to create a match. Bejeweled 2 introduces the ability to create two new gem types. Matching four produces a "power gem" that detonates if matched with similar gems. Creating five-gem matches forms a "hyper cube," which clears the entire board of the gem type it touches during a swap.
