Tetris 2 offers a unique twist on the classic puzzle game. The story revolves around clearing the field of blocks in a different way than its predecessor. Each play field begins with distinct colored dots - black, gray, and white - with one of each color flashing. These dots contain blocks made up of the same three colors.
Gameplay is where things get interesting. Instead of clearing the blocks themselves, you must match blocks of the same color over the top or to the side of a dot to clear it and those blocks from the screen. If a flashing dot is cleared, all corresponding dots of the same color will be removed as well. The goal is simply to clear the dots; completing the round requires clearing them without touching the blocks.
