You might also just see heavily juiced games, like -115 or -120 lines, terrible payout parlay cards, etc. It's probably also worth pointing out that even though the Vegas sportsbooks routinely complain about low margins, the offshore books manage to make a killing despite most offering some combination of -105 lines, offering substantial deposit bonuses and paying payment processors. The idea that a book can't make a substantial amount of money dealing -110 lines on shore is absurd. The theoretical hold on -110 lines is 4.55% per dollar wagered compared with just 2.38% for -105 lines. From what I've seen, most of the Vegas books aren't a patch on the likes of Pinnacle, Bookmaker or BetOnline as far as actually running a book goes. Even 5Dimes would put them to shame.
