Thanks to all for taking time to respond. I'll try to answer as best I can.
tripadvisor.com certainly has several posts on Rainbow Jackpot, none of them good. There are some others out there but they may not show at the top of the search hit list. Here's one -

"Also, Grand Princess Casino was a beautiful casino on the outside, with an empty atmosphere on the inside. There was also a corrupt game called "Super Rainbow Jackpot". If you are looking to give your money away, then play it. If you want to win, stay away. They took cash and credit at the table, which we thought was very odd to take credit at the casino table."
here's another (It also references tripadvisor but I don't remember seeing this one before now. This is really interesting because it appears that there are also several locations in Dominican Republic running similar operations. I had no idea!) -

RIPOFF!! Beware of the Grand Princess Casino in Antigua located at Jolly Harbor. This place is a ripoff. As you walk in you will be greeted and directed over to a "progressive" game. Where after a one sentence explanation of the way the game is played, you find yourself in the middle of the game. I lost over US$6,000 in a space of one half hour. With this game you use a four foot pole with a scoop at the end to get a ping pong ball. The balls have a number which correspond to the other numbers on the table. The dealer is very good about directing your eyes and attention to the table, so you almost never get to see the numbers on the balls. The dealer also lies to you by telling you that certain numbers are good for you, but in reality they are the ones that put you in a hole really fast. In essence those numbers required you to continue to double your bet, until you run out of money. Stay away from this place, and tell all your friends.
United States
1. Are the balls physical or virtual?
A. Real live ping pong type balls
2. What is the largest number available on any given ball?
A. Not entirely certain but apparently the set includes the numbers 112 and 120 thru 129 which all cause you to lose.
3. What is the distribution of the numbers that are available?
A. I don't specifically know that. What I can say is that players invariably draw a number between 50 and 80 on their first turn and then get progressively smaller numbers on each successive turn. This doesn't seem like random chance when every player reports getting consistently diminishing numbers.
4. How many balls are chosen per turn?
A. Exactly one ball.
5. Are the balls selected by the player or a machine?
A. The player uses a pole to scoop out one ball as they are all blown around in a jet of air. HOWEVER - it is grabbed and read off by the dealer/operator before being quickly tossed back into the machine.
Imagine a ping pong ball. Now put the number 120 onto the ball in black ink but space out the numbers - 1 2 0
What one player is suggesting is that the operator is using sleight of hand to conceal either the 1 or the 0 in order to manipulate the score. Its not too hard to imagine how this could be done by a skilled operator. He actually claims to have caught him doing it.
I don't know how I can "prove beyond any reasonable doubt" that the game is a cheat. I do know that I have been hearing horror stories for years and years about visitors to Antigua leaving in tears after a visit to the Grand Princess. It is true that their own greed got them into a mess.
There is a newsgroup site at

Some years ago there were dozens of posts on the site about Rainbow Jackpot and for a time these could be searched and located from the archives. They appear to be no longer available which is really unfortunate. However, the game and its history are quite well known to the regular subscribers. If anyone here wants to get an independent opinion then by all means post a query to the group asking for any information on the Rainbow Jackpot at Grand Princess Casino.
