Wagering contests for sports are just not that effective, and it's why bookies prefer to push for parlay or multiplier contests instead, because gamblers tend to lose a lot with those kinds of bets.
Biggest parlay odds winner… feels like that’s way harder to pull off compared to slots. In slots, anyone lucky enough can hit a x10,000 multiplier, but in sports betting, that kind of return seems almost impossible. I wonder why there aren’t many contests with this format. If there was one, I’d be happy to join. It’s not even that costly since parlay results take time and aren’t instant like slots.
