ZetriX

Zetrix is a freeware Tetris variant, in which the player can choose between ten different languages, four difficulty levels (easy, medium, hard and impossible), which distinguish from each other in the falling blocks' speed, four different table sizes and two game modes.

Several various shaped blocks are falling down the screen and the player has to combine them to rows by rotating and moving the blocks with the keyboard. When there are no empty spaces left in a line, this particular row disappears. After completing ten rows you reach a higher level and the speed increases. While playing the table moves and a background animation, which changes in every level, tries to complicate your concentration. Apart from these deactivatable features and the improved graphics, Zetrix plays exactly like Alexey Pajitnov's classic, at least in the classic mode.

There is also an enhanced mode, which offers additional differently shaped blocks and bonus tiles. Completing a line in which a bonus tile can be found has different effects, depending on the tile. A dynamite filled tile destroys all blocks in its surrounding area, a tile filled with a dollar sign adds 1024 to your score, a transparent blue tile is filled with water and increases the water level at the bottom of the table making it harder for the player and a shining red tile lets the water decrease again.

Furthermore, Zetrix offers a multiplayer mode for two players. Playing in a splitscreen mode either via TCP/IP or at the same computer one can choose between three different modes. In the duel the player with the most points win, in the race mode the one wins who has completed 50 rows first and in the co-op mode the players work together.
