Unusual for a slot machine?

[smoothgrh]

I noticed that on this Bally Big Spender slot machine for sale on eBay, to the right of the reels is what looks like a tiny version of the reel strips. The symbols that appear in the window match the reel strip. Is this what originally appeared on the glass? Not like a casual casino player was calculating odds in the 1970s, but doesn't it seem weird to put that information on there?

The strip beside the reel appears to represent the order of the symbols. You could use this information combined with the paytable to theoretically calculate the payback.
I would have to see the machine play but starting with the early IGT M slots (early 70's) they had virtual stops. Those were the spots between the symbols.
If you don't know how many of these there are then the payback is still a mystery.


What is interesting is the top glass is littered with bars showing a 200 coin pay out, then there is 7's, Stars and targets that have the same payout. This is quite the unusual pay table.
Four reels is also another anomaly that never caught on. 3 & 5 are common. In most Asian cultures 4's are unlucky. I don't like to generalize but Asians tend to be prolific gamblers.
Ie Mako is 3x the size of Vegas. In North American Hotels you often don't see a 13th floor, and in Japan you will never see a 4th floor.

I wonder if the owner of the slot just wanted to see what the reel strips are while playing, and just made a perfectly sized re-creation that was perfectly placed on the right side of the reel windows. It doesn't seem like the kind of art that would be purposed placed there by Bally.

My amateur mathematical calculation is that the odds of three 7s is (2/22)*(1/22)*(1/22)=.00018 or about 1 in 5,000.

The odds of four 7s is  (2/22)*(1/22)*(1/22)*(2/22)=.000017 or about 1 in 50,000.

Your math for 7's looks correct. .... provided there are no virtual reel stops.
One of my S+ slots has a 16 symbols but 64 stops. That changes the odds dramatically.


Actual odds calculations would encompass all of the combinations that would have the same payout.


Since the odds of hitting 4xbars, 4x double bars, 4xTriple Bars or 4xTargets would be pretty much the same. I think you divide the 1 / 50000 by 5
In addition the payback would also vary depending on the number of coins played.


There is nothing that would indicate that this is a multi-coin machine.

I know in some European countries (to this day even) they are required to show the correct reel strips order and odds of each stop on slot machines.  You'll see this sort of thing (little diagram and odds) on the glass and have much more information about the game.  I'm mostly familiar with Germany, so don't know where else it applies, but I've seen this almost everywhere there.

That must be it! The denomination on the glass is 25ct, so I assume that's European currency.

The reel strips shown look just too perfect, so the manufacturer must have placed it there!

The Netherlands had a 25ct coin.

That ended in 2001 with the introduction of the Euro.
Euro coins are 20c no 25c. (not sure if the c is correct or not).

If you look close at the payout legend to the right side of the reel are bonus symbols. They don’t have to be in any order. I had a Big Spender in Red Glass about 10 years ago, and mine was the same way. I with that I had not sold it now. It was a fun game to play. How much are they asking for it?

They're asking $900 or best offer in Medinah, Illinois—local pickup only.

Seems a little high, but these are a rare/harder to find model.

That's cool! So if you got 2 bullseyes and 2 stars, would you get paid 4 coins?

It’s been a long time but I think so.

They were made that way, this one was reworked in the early 90's with the wide reels.  Yet they used the original top glass.
