It's not slots will give higher chance to hit high multipliers compared to sports, but it makes possible.
I think people would be fine spinning $0.05 over and over even though they lost $1,000 in the end rather than someone who betting $1 on parlay with 1,000x odds in 1,000 bets. People might be fine when they make 10 bets, after they reach 50 bets, they're exhausted, after they reach 100 odds, they think it's wasting time.
