Not Tetris 2 is the spiritual successor of the classic Tetris
mixed with physics. The result is a fun spinoff in which blocks
are no longer bound to the usual grid. Blocks can be rotated and
placed at any angle, resulting in a complete mess if not careful.
And with the newest cutting edge technology, Not tetris 2 allows
line clears when the lines are sufficiently filled. The old mode
is still available for play and is now called Stack.
