It wasn't blackjack, but the first time I played baccarat in around 15 hands there were 12 ties. I started with 50 dollars, as I always do on any game, I hadn't played baccarat in my life so I didn't know what was normal and what was not, the dealer couldn't believe it either. I read online that there is a less than one in ten chance of a tie. I made a lot of money on that table, I mean a LOT of money ^_^ But if I had of known about the odds of a tie coming up, I wouldn't have bet on it at all. Also that same table, three perfect pairs in a row and two of them were PERFECT perfect pairs, 20:1 payout. The odds of a perfect pair are also quite low, I didn't bet on those though
But yeah, even though I made around a few thousand dollars on that table (and a few thousand dollars is a lot to to me, like seriously a lot), I wont be doing it again now that I am informed of the actual odds.
EDIT: It was mini baccarat actually
