Yep. Beat the closing line 3 times in a row on bets of more than $100 and you’re limited to like $7.23 per bet on large markers and like $0.16 on props.

Props get limited a lot and very quickly.

The house USUALLY wins, it doesn't ALWAYS win, but when it doesn't win it simply chooses to not let you play.  Must be nice to stack the deck in your favor like that.
