Absolute Tetris Cup allows you to play six different kinds of tetris and to take part in the World Championship. It is not just a clone of the famous Tetris \"fill the lines\" game: It includes completely new variants with hexagons and triangles in place of squares. This change is not as simple as it may seem, since with these new rules the main skill a player needs shifts from the quick reaction to quick thinking and geometric imagination. The classic version of tetris is also included, along with the pentix variations. Nice and funny graphics makes watching it no less a pleasure then playing. All games can be played at different skill levels, you can adjust the speed of falling pieces, as well as acceleration, or request the preview of the next piece. Other handy functions, like game saving and restoring are available. You can play in two different modes: training and tournament. The World Championship will make the Absolute Tetris even more fun for you, if you like to compete not only with computer, but with other players too. The best scores you achieve are submitted to the server, and the World Champion is determined once a month.
