These are some pretty brutal stories, my biggest horror story was on Roulette. One time online with lightening roulette landing a 200x on my biggest number, just as I was going to re deposit after a small session. This also happened to me in a live casino when I was pumping a few numbers quite hard. Left the table for 2 mins to get more cash and my jackpot number rolls in. Would have been 4k online that I missed by re depositing, and 3.6k live. Both times gave me that feeling of absolute sickness that you speak about. Both times tilted me pretty hard, and both times I needed a beer afterwards. Not really life changing money for me but missing them both by potentially 1 or 2 spins whilst I got more cash was heart breaking.
As for Monopoly live I am not a fan of it, as I do think the dealers know an area of the wheel to spin it, that being said I also think this of roulette yet still play the damn thing haha.
Chin up over the near miss, hopefully your time will come
