In a modern slot machine,
the odds of hitting a particular symbol or combination of symbols
depends on how the virtual reel is set up. As we saw in the last
section, each stop on the actual reel may correspond to more than one
stop on the virtual reel. Simply put, the odds of hitting a particular
image on the actual reel depend on how many virtual stops correspond to
the actual stop.
In a typical weighted slot machine, the top jackpot stop (the one with
the highest-paying jackpot image) for each reel corresponds to only one
virtual stop. This means that the chance of hitting the jackpot image on
one reel is 1 in 64. If all of the reels are set up the same way, the
chances of hitting the jackpot image on all three reels is 1 in 643, or
262,144. For machines with a bigger jackpot, the virtual reel may have
many more stops. This decreases the odds of winning that jackpot
considerably.
The losing blank stops above
and below the jackpot image may correspond to more virtual stops than
other images. Consequently, a player is most likely to hit the blank
stops right next to the winning stop. This creates the impression that
they "just missed" the jackpot, which encourages them to keep gambling,
even though the proximity of the actual stops is inconsequential.
A machine's program is
carefully designed and tested to achieve a certain payback percentage.
The payback percentage is the percentage of the money that is put in
that is eventually paid out to the player. With a payback percentage of
90, for example, the casino would take about 10 percent of all money put
into the slot machine and give away the other 90 percent. With any
payback percentage under a 100 (and they're all under 100), the casino
wins over time.
In most gambling
jurisdictions, the law requires that payback percentages be above a
certain level (usually somewhere around 75 percent). The payback
percentage in most casino machines is much higher than the minimum --
often in the 90- to 97-percent range. Casinos don't want their machines
to be a lot tighter than their competitors' machines or the players will
take their business elsewhere.
The odds for a particular
slot machine are built into the program on the machine's computer chip.
In most cases, the casino cannot change the odds on a machine without
replacing this chip. Despite popular opinion, there is no way for the
casino to instantly "tighten up" a machine.
Machines don't loosen up on
their own either. That is, they aren't more likely to pay the longer you
play. Since the computer always pulls up new random numbers, you have
exactly the same chance of hitting the jackpot every single time you
pull the handle. The idea that a machine can be "ready to pay" is all in
the player's head, at least in the standard system.
Truck Stop is a five reel, nine payline, and nine
coin slot machine. The multiple paylines increase
your chances of winning.
Truck Stop has a wild symbol, and a scatter symbol.
For every coin that you bet, you enable another payline.
You are paid out for winning combinations on enabled
paylines only, except for Scatter wins. The Scatter
Horn symbol can appear in any position on any of the
reels.
The Wild Beer symbol does not complete a scatter symbol
combination.
Winnings are paid out on the highest combination
on each enabled payline only, except for scatter wins.
Scatter wins are added to payline wins.
You are paid out for winning combinations on enabled
paylines only, except for scatter wins. The Scatter
Horn symbol can appear in any position on the reels.
The Wild Beer symbol does not substitute for a Scatter
Horn symbol.
Malfunctions void all plays and pays.
The Wild Beer symbol is a wild symbol. This means
that it substitutes for any other symbol to complete
winning combinations, except the Scatter Horn symbol.
The Wild Beer symbol only appears in reels 2, 3
and 4.
Only one winning combination is paid out per payline.
If there is more than one possible winning combination
on a payline, you are paid out the value of the highest
combination only.
The Wild Beer symbol does not complete a Scatter Horn
symbol combination.
Example:
1. One Wild Beer symbol on reel 2, and two Scatter
Horn symbols scattered anywhere on the five reels,
do not complete a winning combination.
The Wild Beer symbol cannot substitute for a Scatter
Horn symbol, and three or more Scatter symbols must
be displayed to complete a scatter winning combination.
2. Two Wild Beer symbols displayed on reel 2 and
3 of the third enabled payline, and a Sign symbol
displayed on reel 1 of the third enabled payline,
completes a winning combination of three Sign symbols,
and pays out 20 coins.
If you selected a 0.50 coin size and bet on 9 paylines,
your total bet amount is, 0.50 credits x 9 paylines
= 4.50 credits.
Therefore your total payout is, 0.50 credits bet
per payline x 20 coins = 10 credits.
The Scatter Horn symbol is a scatter symbol. This
means that it does not need to appear in a line on
an enabled payline to win.
It can be scattered anywhere on the five reels, provided
three or more Scatter Horn symbols appear.
Scatter wins are calculated by multiplying the Scatter
Horn symbols payout, as shown in the Payout Schedule
by the total number of credits bet.
If you have a scatter win and a regular win, you
are paid out for both wins, as the scatter symbol
does not need to appear on an enabled payline to win.
The scatter win is added to the payline win.
Example:
1. One Scatter Horn symbol scattered anywhere on the
five reels, and two Wild Beer symbols displayed on
reels 2 and 3 do not complete a winning combination.
The Wild Beer symbol does not substitute for a Scatter
Horn symbol, and a minimum of three Scatter Horn symbols
complete a winning scatter combination.
2. Three Scatter Hornsymbols, scattered anywhere
on the five reels, completes a scatter winning combination
as shown in the Payout Schedule. Three Scatter Horn
symbols pay out the total number of credits bet multiplied
by 10.
If you have selected a 0.25 coin and bet 1 coin on
each of the 9 paylines, your total bet amount is 0.25
x 1 coin = 0.25 credits per payline x 9 paylines =
2.25 total credits bet.
Therefore your total payout is 2.25 total credits
bet x 10 = 22.50 credits.
3. Three Scatter Hornsymbols, scattered anywhere
on the five reels, and three Ten symbols displays
on reels 1, 2 and 3 on an enabled payline, complete
two winning combinations as shown in the Payout Schedule.
If you have selected a 0.25 coin and bet 1 coin on
each of the 9 paylines, your total bet amount is 0.25
x 1 coin = 0.25 credits per payline x 9 paylines =
2.25 total credits bet.
The three Scatter Horn symbols complete a scatter
winning combination and pays out the total number
of credits bet multiplied by 10. So, you are paid
4.50 total credits bet x 10 = 45 credits.
The three Ten symbols complete a 3 Ten symbols winning
combination and pays out 10 coins. As you selected
a 0.50 coin size, you are paid 0.50 x 10 = 5 credits.
Therefore, your total payout is 45 credits for the
scatter win + 5 credits for the regular win = 50 credits.
Chain Mail bonus slot is a 5 reel, 20 payline, 200 coin slot machine with a wild/multiplier symbol, a scatter symbol, and a Castle bonus game. Three Bonus Gate symbols displayed on reels 1, 3 and 5 activate the Castle bonus game. There is no payout for any Bonus Gate symbol combination. In the Castle bonus game there are five rows of seven doors. You choose one door from each row to reveal your bonus win amount. The Castle bonus game has two special symbols, the Princess Roxy symbol and the Uncle Mordread symbol. If you find the Princess Roxy symbol, you are paid all the win amounts behind each door in that row and move to the next row. If you find the Uncle Mordread symbol, the game ends and you are automatically returned to the regular game.
