No-Win Slots, Keno Machines, Triple Play, Machine Percentages
by John Grochowski
Q. My wife and I have great difficulty believing that casinos
don't lock down some, if not all, of their slots periodically. Of
course, we're not there 24/7 so maybe somebody does get something. When
we are there, we have observed that during these lock downs, we are not
the only ones getting little or nothing, but that other players (playing
all variations of denominations, machines, and strategies,
minimum/maximum wagers) have the same nothing results. We have
occasionally seen one person (usually a woman and I'd swear the same one
all the time) hit a big jackpot.
Is it pure coincidence that many machines in the same area
consistently produce almost nothing between the hours of 8:30-11 a.m.
and then there is only one pretty good hit in each of them between 11
a.m. and 1 p.m. (Yes, I know, play them between 11 and 1.)
A. Any difference you're noticing really is pure coincidence.
The only way to change the frequency of hits is to change the random
number generator chip that drives the machine. To do that, the casino
would have to open the machine in the presence of a gaming board agent,
break evidence tape, remove the chip, put a new chip in, reseal in
evidence tape, lock the machine back up and have the gaming board agent
sign off on it. It's too big a process to do routinely.
Soon, the process will be speeded up by server-based gaming, but
the process of changing games still will require regulatory supervision
in most jurisdictions, along with a short period of an on-screen display
letting players know a change is taking place.
If you actually charted the results night after night, tracking
every spin in your designated times, I think you'd find over a period of
months that there really is no difference in payback percentages. Over a
period of 100,000 to 300,000 spins of the reel, the machine will come
very, very close to its targeted payback, and the game doesn't know what
time it is.
Q. I enjoy playing video keno, but recently both casinos where I
play removed the popular Cleopatra keno game (as well as Power Keno).
Can you tell me why? Was it some sort of licensing issue?
A. I don't know the specifics at the casinos you visit, but
usually when a game is removed it's because it's not earning as much for
the house as other games, and the operators want to try something else.
Video keno has a couple of built in problems, as far as
operators are concerned. It plays a little slower than slot machines
because it takes more time for numbers to be drawn and displayed and for
a player to look them over than to spin slot reels. Fewer plays per hour
means less money for the casino. Also, keno players tend to bet fewer
credits per play than slot players.
Casinos that use video keno do so in hopes of reaching an
audience that otherwise wouldn't come to the casino. But eventually,
someone with an eye on the bottom line sees that they don't earn as much
per unit as other machines, and they get taken out. If business then
drops, sometime down the road a new slot manager might decide that keno
might help draw people in. It's a bit of a circle.
Q. In your opinion, is there any advantage or disadvantage to
playing a Triple Play video poker machine versus playing a single-play
video poker machine? If it deals you a pat hand it is a big advantage,
but overall do you think one is better than the other?
A. If the paytables are the same, the odds are exactly the same.
In the long run, if you make $10,000 worth of bets on a Triple Play
machine, you're likely to wind up in about the same place as if you made
$10,000 worth of bets on a single-hand machine.
Multi-hand games smooth out volatility a little. It's a little
less bumpy ride, because there are fewer hands where we lose the entire
bet. Dealt a pair, we have three chances to make three of a kind instead
of only one. Of course, if we draw the three of a kind on only one hand,
we're just getting our money back instead of making a profit.
Personally, I enjoy the multi-hand games. But odds-wise, it
makes no difference.
Q. I have had people tell me that you should play the max
because machine percentages go up as the bet increases. I am wondering
if that is true. Considering penny slots, are machine percentage payout
percentages increased if you play $2.50 as opposed to 25 cents?
A. That is true on three-reel slot machines, because there is
disproportionate increase on the top jackpot when you play max coins.
For example, a machine might pay 500 coins for three jackpot symbols
with one coin bet, 1,000 for two, but then jump to 2,500 for three
coins. That leads to the higher payback percentage.
Most video slots don't have that disproportionate jump, so on
most video slots, as long as you cover all the paylines, the payback
percentage is the same no matter how many coins you bet per line.
However, some games have symbols that don't become winners until
you raise your bet. A video version of Bally's Blazing 7s, for example,
mirrors the reel-spinning game in requiring higher bets to first unlock
the bar symbols and then the 7s. If you're going to play the game, be
sure to wager enough to make all symbols active.
Do watch out for progressive slots. If you're going to play
progressives, make sure you wager the amount required to be eligible for
the progressive jackpot. If you don't want to bet that much, play a
different game.
