While the gameplay borrows from 1991\u2019s Dr. Mario in some respects \u2014 the initial level setup of some isolated blocks or groups of blocks to clear, previously static pieces that become detached through matches and fall until they hit something solid, falling blocks being made up of different colored blocks, the manipulation of blocks in order to maneuver them into the tiniest spaces you can, my being nowhere near as good at the game as my wife \u2014 it also differs in some pretty important other ones. You don\u2019t have to clear all of the blocks that the stage starts out with, for one: in Dr. Mario, all of those viruses have got to go, but in Tetris 2, you just need to match and clear the few with a flashing white light on them \u2014 hence the Japanese name of the game. The block shapes are also wildly different, too, and that\u2019s where some of the Tetris comes in: these do look like Tetrominos! Sometimes kind of warped, mutated ones in new shapes and arrangements, and sometimes only very loosely connected so that when you put down one angle of a piece the rest just slides off and keeps going, but in Dr. Mario you just had colored pills that were always that same two-block size. So this is clearly much more Tetris than Dr. Mario, shapes-wise.
