Sorry to hear you had some problems. Can I ask what browser(s)/device you were using? Or what game you were playing? I have a few other exceptions/stacktraces to look into, any extra info would be helpful.

Good idea with the pubs. I also considered approaching places with Karaoke rooms. Like a little private game room party while you are out.

Most of the games are designed to be playable with 3-16 people (even 16 is pushing it for some). Would potentially need to design some games for a larger audience in a bar.
