I haven't played it yet. I was trying yesterday, but there were not enough players. I need to find out when everyone is going to attempt and try my luck then, although in NZ timezone it is rather difficult.
I think you would need to be up really late/early if there's not enough other people in NZ ^_^; Hope you manage to cross over with another player soon :D
Do you want to try it? Yourself, since you are around? I am there right now... just want to see if I can see you joining.
I can give it a shot so you can get a game, you'll have to talk me through it like I'm an idiot though XD
no worries... so head to https://arena.hive.uno (login with keychain). Use the PC browser for now, the keychain internal browser is not yet able to work with this.
Then you click workshop to start and you will have to click on your posts that will appear... takes a bit and the scanning will show you what "cards" you will have depending on the post.

Should look like something like this...

Then once all are discovered, you go back and start a game... on the "Play" button... you then need to select which cards/posts you re going to play with...
And then click find match...

I have no idea what just happened or what was going on XD but I hope you had fun? :)
Ah.... you will have to use PC, just tried and it does not work very well on keychain browser yet.
I use the big rig for most things, a little bit too addicted to my multiple big screens ^_^; I can't get keychain on my phone :<
Didn't install Google Play (using GrapheneOS and have successfully not needed it so far) and the keychain version on github (via Obtainium) is old and doesn't run.
