Decahexatris

The highest combo you can get in the latest installment of the Tetris franchise, Tetris Effect. A Decahexatris is achieved by accumulating a 16 row combo when the mode Zone is active (which is activated when the player fills up the meter by clearing lines, which then puts the game in a state where the blocks are frozen in place until the player decides to move them). Once the Zone meter goes down, it allows players to essentially clear 16 rows at once, beating the past highest row combo you could get which was 4.

Friend: Dude, I think Trey is going to get a Decahexatris

Me: No way, that's nuts!
