But be careful if you join in. How they handle the "residual" can be slippery as most pay out in whole/even dollars which may leave a fair about of money left over (i.e., "residual"). On some cruises, the person who amassed the highest amount in their turn, gets the residual. On our cruise the organizer kept it so as to take care of "the taxes, etc" and for the hassle of running the slot pull. My sister and BIL had run many slot pulls on cruises before, and said the points on the cruise line for the gambling is significant enough to make running the slot pull worthwhile. She told me that for the organizer to ALSO take the residual was a farce and rip-off, so we didn't participate.
