Twintrix is heavily inspired by the Atari ST classic Klatrix which is a mixture between Klax (Ataris attempt to steal the puzzle game crown from Tetris) and Tetris itself. Its also similar to countless other puzzle games like Columns. The principle behind Twintrix is simple connect rows of identical tiles to destroy them. The minimum length of a row is 3 tiles and they can be in any direction. Several rows can be destroyed at once and when the remaining tiles fall down new rows are often created causing further destruction and giving more and more score. The more tiles you destroy per move the more you score. Tiles fall down the screen in groups of 3 these can be shuffled into the required order then dropped onto the piles at the bottom of the screen. The next set of tiles is displayed always a good idea to plan your next move before the current tiles fall home. The game is over if any tiles reach the top of the screen. Twintrix is for 1 or 2 players. Players can play independently or Head-to-head. In head to head mode - the game is identical except when you advance a level you punish the other player with a fresh row of tiles that push their existing tiles up. Once a players game is over the game continues for the other player so they can build on their score but they can also start a single player game for themselves. This version of Twintrix was developed in Play Basic (www.PlayBasic.com) and only requires DirectX 3.0 or above.
