That’s 100 coins more than the 2,400-coin jackpot this machine would pay if it were a Straight Multiplier. Sometimes the bonus is quite large. A Red, White, and Blue machine, for example, pays 2,400 coins for hitting red, white, and blue.

Another interesting aspect of the machine are the name(s), handwritten in pencil on the inside of the machine. It looks like “Chas Drebe [Lon?] Otto Berger”. But we have not been able to find any record in the history of this (or these) individuals, so we are not yet sure what his connection to the machine was. Maybe he was the one who made the modifications to it, and then proudly signed his handiwork, like so many artists.
One of the most fun aspects of the machine is figuring out how it worked. With the help of our friends over in maintenance again, we began to figure out some of the details about how it worked. The wheel is divided into 138 sections, each in one of seven colors that corresponds to a pay-out value of 10 cents (red and black), 25 cents (green), 50 cents (cream), $1.00 (pink), $2.50 (yellow), or $5.00 (blue). A player would insert a nickel, turn the first handle, and the nickel would drop down into the appropriate color track below.

The player could then turn the big handle to start the wheel spinning. If the wheel did not stop on the same color as the bet, the coin was collected in the bag that we see inside the machine on the back. But, if you were one of those lucky individuals who happened to guess right, the pegs at the bottom half of the machine would release the right number of nickels and you could get your “pay-out” in the cup on the side. The machine also appears to have been able to re-load itself, since there is a “bridge” that can be raised and lowered to add more nickels into the track.

Willing to take a chance? Well, it might not be all luck. We figured out the system of wiring on the back of the wheel, which tells the machine what value it has landed on and activates the whole sequence of money (the wires in the slits farthest from the center of the wheel correspond to a lower value). But one peg is blocked by a piece of wood, which makes us think the machine could have been rigged. So miners would place their bets on blue, never knowing that the object itself, and not bad luck, were behind the failure to get the big $5.00 pay-out. Overall, the machine survived the past and came down to us through history in good shape. It was dusty and dirty, but with careful cleaning, I was able to get it back to its old but clean state. I also made a top for it out of archival materials, to prevent dust from getting in the machine when it goes on display in the museum.

It had another type of accumulation too- paint splatter from being in a room that was painted without covering up the objects first. Using a paint that has the special property of being removable if someone wants to take it off the machine in the future (an important consideration in doing conservation work), I painted over the splatter. Some of the other work done on the machine involved using different glues (which are also removable) to secure loose pieces. An example of this was in the case of fixing a previous repair, to the slot where a nickel would go to place a bet on red. The bottom of the slot had broken, and at some point in the past, someone had repaired it with tape.Tape turns yellow and brittle with time, and eventually loses its ability to hold things together, as anyone who has an old scrapbook knows. So I removed the tape and applied a glue that will last a lot longer. Another example is the beading that was applied around the decorative panel on the front. You can see how it has started to pop off. This happens because wood shrinks and expands when the humidity and temperature change. We can therefore conclude that this gaming machine was probably in an unstable environment before it came to the National Park Service. As the panel beneath shrank, the beading had less space and so it came off. This shows how one of the best things you can do to care for old objects, especially wood furniture, is to keep them in places in your house where the humidity does not change as much. This will reduce the chances of the wood warping and cracking, and we will have these beautiful and functional pieces for years to come.

Introduction

In the past I feared to show a concrete example on this page, not wanting to violate copyright laws. However, in the Netherlands, information on the reel stripping and probabilities of each win are sometimes posted on small cards on the machine. A fan of the site sent me the information provided on an IGT 'Red White & Blue' machine.

First, let me present the pay table. For those who are not familiar with the game, a 3-bar is in blue, a 2-bar is in white, and a 1-bar is in red.

After the player makes a bet and presses the spin button, the machine selects three random numbers, one for each reel. These are chosen from a random number generator that is constantly drawing random numbers at a rate of thousands per second. The numbers chosen at the moment the play is initiated are the ones used to determine the final outcome. In other words the outcome is predestined the moment you press the spin button.

In the case of Red White & Blue, each random number has 64 equally likely outcomes. Each random number is mapped to a stop position on what is called a 'Lookup Table.' The following is my estimate of what the Red White & Blue lookup table looks like, based on the total number of stops per symbol per reel, provided to me.

Immediately after the random numbers are chosen they will get mapped to a stop on the machine via the Lookup Table, the outcome will be scored, and the player paid if he won anything. For example, if the random numbers chosen were 26, 8, and 43 the player would get Blue 7, Blank, Red 7.

Note how there are clusters of the same symbol in a row. For example, stops 60 to 62 on reel 1 all are mapped to a 1 bar symbol. These will all be directed to the same 1 bar symbol on the actual reel. There are exactly 22 groups of like symbols on each reel, which is the standard number of stops on an electro-mechanical three-reel slot machine, known as a 'Stepper Slot.'

Also note that only stop 45 on reel 1 is mapped to the red 7 symbol. However the blanks above and below it have five positions each. This causes the often seen near miss effect, where the reel stops directly above or below the highest paying symbol. Many people have written to me, claiming that this near miss effect is against the law. My slot machine Appendix 1 proves otherwise.

To calculate the return of the machine, add up the number of positions for each symbol on each reel, to get the total symbol weightings. The following table shows these totals. This table is what was indicated on the Red White & Blue machine in the Netherlands. The Lookup Table above, was reverse engineered to produce these total weights.

Total Weights for Red White & Blue
Stop Number	Reel 1	Reel 2	Reel 3
Red 7	1	3	1
White 7	6	1	7
Blue 7	6	7	1
3 bar	6	7	5
2 bar	7	6	9
1 bar	6	8	9
blank	32	32	32
Total	64	64	64

With the weighting of each symbol and reel known, it is just take simple math to calculate the return. The following table shows the win, number of combinations, probability, and contribution to the return for all possible events. For example, the table above shows the number of white 7's are 6, 1, and 7, for reels 1, 2, and 3 respectively. The total number of winning combinations for three white sevens is thus 6 × 1 × 7 = 42.

The lower right cell shows a return of 86.58%. That means that for every dollar bet at the one coin level, the player will get back 86.58 cents, on average. Doing the same table for two coins results in a return of 86.58% as well, and three coins has a higher return of 87.47%, due to the disproportionately high win on the top two pays. The standard deviation is 9.03 for 1 or 2 coins, and 10.80 for 3 coins.
