I sailed on the Century last Dec. and you used cash. I believe that is true for all ship casinos from what I have read on these posts.
The Blackjact min. was $5. I didn't check out the pokers min.
As far a slots they had 5 cents, 25 cents and 1.00 machines. They also had video poker machines.
My husband and I were pretty lucky. I walked away with 2700 dollars and he won 500 on a dollar slot. I stuck to the 25cent machines.
Good Luck and enjoy your cruise. Can't wait for mine.
