atari2600land has updated his single and two player simultaneous play variant of a very well known russian block game. The game was previously known as “Tetris”.

Changes:

r1
major update: I’ve added a B-Type to the game. For those who don’t know, B-Type is where you can freely set the level and the height of garbage blocks and the goal is to complete 25 lines. B-Type is one player only and you press the select switch until one joystick appears with a playfield pixel on the left side. Once pressing fire, you can then select level (speed) and height, and then try to get 25 lines.

r2
Fixed the bug having to do with levels with the B-Type.
EDIT: Fixed another bug having to do with B-Type. All bugs should be fixed now (hopefully.)
