Bejeweled 2 (also referred as Bejeweled 2 Deluxe in some releases) is a tile-matching puzzle video game developed and published by PopCap Games. Released as a sequel to Bejeweled, Bejeweled 2 introduces new game mechanics, such as Special Gems and extra game modes, along with new visuals and sounds. The game was originally released on November 5, 2004, and has been ported to several platforms following its release, including game consoles, smartphones and in-flight entertainment services. Gameplay Like its predecessor, Bejeweled 2 involves swapping two adjacent gems to form a line of three or more gems of the same color. When three gems are lined up, they disappear and cause randomly generated gems to fall from the top to take the matched gems' place. Sometimes, falling gems automatically line up, causing chain reactions. If the player is unable to find a match, the player can use the Hint button to find an available match at the cost of several points. They can also wait several seconds for an automatic Hint feature to trigger without penalty. Creating matches of four or more gems will create powered-up gems known as Special Gems. When four gems are matched at once, or when the player makes two matches in an L, T, or + shape, a Power Gem is created, which destroys the eight gems surrounding it when matched. When a match of five or more gems is made, a Hypercube is created, which destroys all gems of the swapped gem's color from the board. Two other gems also appear in the Puzzle, Cognito, and Finity modes. Rocks are solid objects that cannot be matched but can be destroyed using special gems. Bombs have a green numerical counter on them that decreases every move. When it depletes to 0, it explodes similarly to the Power Gem. Bejeweled 2 features several different gameplay modes. Five (four if the hidden Original mode is not counted) game modes are available from the start, and the secret game modes (Twilight, Hyper, Cognito, and Finity) are unlocked after reaching specific benchmarks in each of the game modes. If a secret game mode is discovered, a question mark button will appear on the main menu screen, which shows the secret game modes. The Classic mode involves attempting to score as many points as possible before the player runs out of legal moves. Scoring points fill up the progress bar at
