on the rake. they take a percentage of each pot say $1.00 for every $10 in the pot. a good dealer can deal 30-40 hands an hour. so if avg pot is $40 then the house makes about 120-160 an hour. not as profitable as other games but they are giving in to the demand for the game. the one table I hear they have on ships cannot be worth it to the cruise line but they are basically filling a desire for passengers, in my opinion.
