So I thought I would share this news since it's pretty major and I know Ryan hates it. Infinite spin does NOT exist in this game. Once a piece gets to the bottom of the screen/on top of another piece, you can only keep it alive for a few seconds, then the piece gets placed. Sure the leniency is still there to an extent, but you can no longer do it forever which is a huge change to Tetris.
For those of you that don't know, this is where the controversy all began.
