I played in a Blackjack tournement on the Glory in March (didn't win, didn't even make the finals) and here is how it worked: You had to pay for your registration at the Casino Cage, in my case it was $20.00, and they gave you a voucher that you took to the tournement table and exchanged for tournement chips (I think you received $2000 worth, but I can't remember the exact amount). They then play a fixed number of hands (I think it was 10 hands, but again, I can't remember exactly) and after that they count your chips, if you haven't already gone broke :-). The first names of top 7 quailifers are kept on a blackboard (along with their totals so that you can wager accordingly) and any players in the current round that make the list are inserted and the bottom qualifer drops off. You can enter as many times as you wish, as long as you pay the entrance fee each time. At a designated time (I think the qualifying was on for about 3 hours), they announce the names of the finalists on the Casino PA system, and they must assemble by a specified time or forfeit their position (but if there is a forfeit, they don't replace him/her). They are then each given the same amount of tournement chips and they play a fixed number of hands. The person with the most chips at the end wins first prize, which consisted of some cash, a trophy and some ship-related merchandise. I beleive there was also a prize for the top qualifier. I can't remember if there was a second prize, but I don't think so.
Hope this helps, and sorry I don't remember the exact numbers
I entered the slot on the Victory and what you do is pay $20 and they set the machine for so many credits and you basicly just push spin as fast as you can go for a certain amount of time and the ones that have the highest credits get put up on a board and the winner gets $500. There were a lot of people signed up so the real winner was Carnival
Just got back today from the Spirit and my friend joined the Blackjack Tournament. It was $20 to try to beat the dealer in 7 rounds. You can enter as many times as you want (at $20 each time of course) until you are one of the top 7 finalists. He came to the conclusion, wait till the last 2 or 3 rounds to try to qualify. You have to beat the lowest players score to get into the finals. Then you won't be losing $ each time. I hope this helps.
