A very interesting derivative of Jacks or Better was
introduced nearly 15 years ago, with the catchy name of Reversible Royals, or RR
for short. Also known as “sequential royals,” it’s probably
coincidence, but RR originally got its start at our railroad (RR) motif casino,
The game offers a huge jackpot of 10,000 for 1 ($12,500 on a
5-quarter play) for a royal flush in sequence 10-J-Q-K-A or in exact reverse
order A-K-Q-J-10, in any suite. It also offers a bonus payout on
four-of-a-kinds; ranks 2-3-4 pay 40 for 1 while aces pay 870 for 1, all others
remain at the standard 25 for 1. For these benefits, the payout on full
house/Flush is cut to 6/5 in lieu of the 9/6 which full-pay machines feature.
Most players are conditioned to understand that when the pay
schedules of conventional games are “adjusted,” the gimmicking usually
favors the house, in the long haul, by reducing the payback percentage. So, it
is not surprising to find that is the case with RR. But, in the case of RR, the
cost to the player is very small, indeed, considering the added volatility
introduced by way of the mini-jackpot on four aces, together with that RR
jackpot (a down payment on a house, maybe), the game should be attractive to
Let’s look at what the schedule changes imply, first
assuming that the playing strategy (ranking) for full-pay Jack or Better is
utilized. Since the royal flush is hit an average of once in 40,000 games only
two of the possible 120 arrangements will be in the winning sequences, we can
estimate that the big jackpot will be hit an average of once in 2,400,000 hands.
While that may be discouraging, the extra 9,300 bet-units (10,000 minus 800) is
worth 0.38 percent in overall payback.
To a very close approximation, four-of-a-kinds occur equally
often in all ranks. With 80 for aces, 40 for the 2-3-4s and 25 for all others,
the average payout on quads is worth 1.82 percent in payback, because those
quads hit an average of once in 423 hands. To be exact however, we must reduce
this figure to 1.62 percent to recognize that we frequently break up pairs of
2-3-4 ranks in pursuit of flushes, thereby causing few quads in these ranks.
Combining these two “pluses” gives us 2.0 percent,
which is nearly equal to the 2.3 percent loss resulting from the 8/5 schedule.
At this point we should consider what we might achieve by expert play in
adjusting our strategy which causes a lower-value ranking to move up to a
higher-value ranking will swing the payback percentage our way.
For example, in Jacks or Better, we play all pre-draw
triplets like: 10C-JC-QC-QH-QS in that exact order, by holding the matching
cards, simply because the Expected Value (EV) of the triplet is 4.3 whereas the
EV of the three-card royal is only 1.4. In RR, the super-high jackpot makes the
EV of this particular (sequential) three-card royal, which is a jackpot
candidate, over 5.8. Accordingly, any triplet that includes a sequential
three-card royal is played for the royal.
As another case, consider the hand: 10D-4D-QD-KD-7D, in that
exact order. This would be a pat flush worth 6 in Jacks or Better but in RR it
is worth only 5. Therefore it is expert strategy to play this as a three-card
royal with its EV of 5.7.
Similar examples occur is straight and two-pair hands. With
expert strategy for RR, we can virtually restore the payback to the 99.6 percent
level we attain in full-pay Jacks or Better.
