games 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.
