(I stuck the battle royale tag in there for a laugh)

Anyway. Has anyone else tried this? It's surprisingly addictive. Really simple, really slick.

I've done reasonably well so far but I think I'm missing a gameplay element and I'm hoping someone can help.

I confess that while I've played lots of Tetris. I've never really played multiplayer Tetris. So I don't fully understand how it works. Last night I managed to grasp how to target individual players and also how to quick target groups of players, like those who are near KO or are targeting me.

What I don't fully understand is how to trigger an actual attack. I always felt like I was doing it by accident last night.

Is it purely a result of achieving a bigger move like a Tetris or a clear, for example? Or should I be doing something else to send those terrifying grey blocks to other players?
