The New Tetris

In this new version Tetris, from the same people that brought Tetris into the 3D sphere world, you can now play a 4 player game, and dump your cleared lines to another player using 'garbage'. In the single player mode, the total lines cleared in every match that you play are added up, and once you reach a certain amount, a famous monument will be unlocked, and you can view them from all angles in full 3D. The process can be sped up by building four-by-four squares out of pieces, which will turn into silver (and for squares made of four of the same piece, golden) squares that grant bonus lines.
