Where is the Hard Drop option?
If you are playing multi mode or single player (not adventure mode) go to the right most option before you can play a match, choose the right most menu.
ハードドロップ
Set this to ON for it to work with Puyo Puyo.
Default means it is on for Tetris, but not Puyo Puyo.
If you have this on Xbone, add me Izuna Lasky
The code is for the smartphone game. I mod a message board with a few players so if you (or anybody else in this topic) don't care about the code, PM it to me and I can distribute it to people who can make use of it.
As for why you can't find anybody online, well, this should explain everything

I thought the Arcade game was Puyo Puyo Quest... ah wikipedia told me there is a smartphone version.
There are a decent number of players on Xbone for this, but I guess they either don't want to play online or matchmaking is looking at our latency and saying NOPE.
