Would you want to get lucky with a dealt royal flush, or just with the normal "distribution" of royal flushes?
Let's do the math:
A dealt royal comes about once in 629,740 hands of play.
A royal flush in general comes about every 42,000 hands. This figure is approximately averaged over various types of games because, for example, a natural royal in deuces wild games come about once in approximately 45-thousand hands. In Jacks or Better, a royal is supposed to come about once in approximately 40,000 hands.
This means you should have about 15 drawn royals for every dealt royal. Well, I'm way behind on the number of drawn royals. But I have been dealt a royal flush twice -- once on a nickel 50-play machine, and once on a $5 progressive machine. But if I could exchange my two dealt royals for 30 drawn royals, I would be very happy to make that exchange because I would come out ahead.
My dealt royal on the $5 progressive was for $36,000. But if I could exchange that for 15 drawn royals at the same denomination, I would have grossed $300,000 (15 X $20,000) or $264,000 more.
My dealt royal on the 50-play machine at 5-cent per coin was worth $10,000 -- a tidy sum. But if I could exchange that one dealt royal for 15 royals on a $1 game paying $4,000 each I would gross $600,00 instead of the $10,000 payout on the 50-play machine.
Bottom line: if I am going to get lucky, I would rather get lucky with more drawn royals than one dealt one.
