I posted awhile back explaining how to play local multiplayer on Tetris Ultimate on the Xbox One, and now I figured I’d add a how to video to make it even simpler.

The game doesn’t explain how to add additional local players at all, so it took me awhile to figure it out at first. Basically the second player needs to login and then they need to push ‘A’ to be added to the local party. Hope this helps you out if you were confused!
