of the same colour as the bomb to instantly clear from the playfield. Hexic offers two variations on the standard Marathon mode: In Timed mode, a timer constantly counts down toward zero, and the game ends when time runs out. The amount of time increases with successful clears, and resets to its maximum value when the player forms a starflower. Creating starflowers also increases the maximum amount of time available, up to two minutes. Survival mode challenges the player to completely clear the playfield. Unlike in Marathon and Timed modes, clearing pieces from the playfield does not automatically cause new ones to fall from the top. Instead, the player forms clusters and flowers until no more moves are possible, then any remaining pieces are locked in place and all open spaces are filled with new pieces. Clearing clusters with bonus stars causes nearby locked pieces to become unlocked. Forming a flower unlocks all pieces on the board and causes all pieces the same color as the center piece in the flower to clear from the board. If the player successfully clears the entire playfield or survives fifty rounds, they win the game. The game is over if all pieces on the playfield become locked. The gameplay music from Hexic HD, released with the Xbox 360 in 2005, is from the album Hexophilia, an experiment in loop-based composition composed by Jerry Schroeder. Development Hexic was originally developed by Carbonated Games and was released on the MSN Games online service in July 2003. A downloadable deluxe edition was also made available soon after. A variation of the game called Hexic HD was later developed by Microsoft Game Studios (since renamed Xbox Game Studios) and Carbonated Games for the Xbox 360, and comes preinstalled on all Xbox 360 hard drives as part of the Xbox Live Arcade service; it was previously only available by calling Microsoft's Service Center but is now available on the Xbox Marketplace as a free download. This version features online leaderboards and support for high-definition. In August 2007, Microsoft released Hexic 2 on Xbox Live Arcade, providing new gameplay features and a competitive two-player mode. Additionally, Hexic Deluxe for Tablet PC was released for Windows XP Tablet PC Edition as part of the Education Pack for Tablet PC, allowing players to rotate pieces using a stylus. Hexic comes with the Zune version 3.0 firmware, released September 16, 2008. In
