I thought I might win one.
Hilarious
I opened 5 tabs of lichess and sent 5 seeks. At first I was using ctrl+tab and ctrl+shit+tab to toggle, but that became too slow so I started using my mouse (I use ctrl+tab when playing 2 games at once and it works really well).
To be honest it doesn't quite count because the total number of moves was 130... a few games went to move 50-60, but some were about 10. I was pretty lucky.
It also helps tremendously that it's unrated. Of course if I played even 2 blitz games at once against people my own skill level I'd lose both games almost every time.
I just played 5 games of 3/0 at the same time.
I won 4
