Try out Tetris man's new game

Tetris creator Alexey Pajitnov has designed a new puzzle game for PC - and you'll never guess, but it's all about lining up falling blocks.

Dwice sees you trying to save a mountain village from death by avalanche, matching blocks of ice before they hit home. Quest mode features 60 levels, while Arcade mode is all about survival - the longer you manage to keep going, the trickier things get and the more points you score.

You can try it out for yourself by downloading the 12.9MB demo, now available from the official Dwice website. The full game costs $19.95.
