Webtrix is a remix of the great puzzle game Tetris. The object of the game is to arrange the falling figures to complete horizontal lines within the playing field. Webtrix starts with a clear playing field (19 cells high by 10 cells wide) and shapes randomly falling one at a time from the top of the playing field. The shapes are made of four adjacent small blocks arranged into 7 different patterns. The player may affect the falling figures by moving them left or right or rotating them clockwise or counterclockwise within the playing field while they are still falling. When a complete line is formed, that line is eliminated from the playing field, and the player scores points. If the player cannot complete lines, the figures eventually build upon each other and reach the top of the playing field, thus ending the game.
