The league I'm in allows preplays but they have to be done in the presence of another league player. Whether the scores are accurate 100% of the time I have no idea and never made an issue of it. Where I play if someone submits what would be a grand champion score their initials should be on the machine anyway.

The reason they're allowed in the first place is to allow people to participate in league and if something comes up like work or vacation you can use preplays instead of taking a forfeit.

True.

I guess you take pinball league pretty seriously then. I just go to drink beer and play pinball.

One night I was in a 3 player group and the other two players weren't there and had preplays. After two games of playing by myself I told the TD just to use my preplays for my final two games and I left cuz it wasn't any fun.

Yeah that league night sucked. But shit happens like real life. What are you gonna do?

Not understanding how that prevents me showing up on league night when nobody else from my group is there.

I was in a bowling league years ago and they had the same rules with pre-bowling. My team would show up and the other team wasn't there. At least in that case we could bowl three games with each other and socialize although it made for a quick night. Playing pinball by yourself on league night sucks though.

Well in my case this happened only 1 time in the over 3 years that I've played in league. I only mentioned it cuz it was the only thing I agreed with OP that playing by yourself on league night does suck. Otherwise, I think the way our league is organized and run is just fine. Just one of those deals for that night...
