(#-4). So, using an extreme example, if a line of 11 Starflowers is made (2 rows of 4, then rotate in 3 in the middle), 7 Rubies are made, and a line of 7 Rubies makes 3 Black Pearls. Detonation – Emeralds, Starflowers, Rubies and Black Pearls can be detonated on the player's command. The explosion causes some of the adjacent pieces to explode, making it easier to destroy "locked" pieces or clear bombs. Chain Reactions – If a piece that is detonated has an Emerald, Starflower, Ruby or Black Pearl next to it, the initial explosion will cause the 2nd piece to explode, which in turn blows up the pieces that are adjacent to it. In this manner, long chains of pieces can be linked together and detonated in a single massive chain reaction. Bug and fix The Marathon mode featured a bug in which saved games would remove the bomb threat from the boards, allowing players to play forever. On September 23, 2007, an update fixed this bug, among other minor tweaks. 2007 video games Alexey Pajitnov games Carbonated Games games Microsoft games Multiplayer and single-player video games Puzzle video games Video games developed in the United States Xbox 360 games Xbox 360 Live Arcade games Xbox 360-only games
