As others have noted, they have an incentive for you to buy more chips. After getting you hooked, they clearly rig the game. In ultimate Texas hold em, the dealer has a slight advantage (52% or so) if you play right. At first I thought I was imagining things but I kept track and it became mathematically impossible. In fact, they seemed to make the math work against you. If you start playing it right— I.e. going 4X when you have a king and an ace or pocket kings— it works against you. When there’s nothing on the table, and you have a high card (say ace) they always have a pair. If you get a straight, they have a higher straight or a flush. If you do win, dealer doesn’t have a pair so you don’t get your bet back. Just too many coincidences.
