Jan 08, 2015 So the casino already knows what the machine is supposed to do. That's not luck! History of the Slot Machine. This is not a history lesson on the evolution of the slot machine itself from mechanical to today's network connected computer. This is the history of how Slot Machines evolved to separate you from your money faster and more effeciently.

What it takes to tighten video slot machines. This is because tightening or loosening a slot can affect more than just the paytable. It can affect the number of symbols on the reels, the spacing, the awards and multipliers on bonus screens – a whole litany of different things. And even if, as it is on some slots.
Jun 15, 2017 ' Do you believe Casinos can 'flip the switch'? Last trip on the way to McCarran airport, the Uber drier told me that the casinos always tighten their slots before the weekend. I answered him: 'Well, you should have told me when I came in three days ago!' I certainly believe the Uber driver more than the Nevada Gaming Board.

In 'how slot machines works' you mention that the Random numbers (1 to 2+ billion) are drawn in a cycle to ensure each number is chosen once per cycle. Are you saying that the slot has a 2+ billion-element table that gets filled with all the possible numbers (over time)? Is this why a slot machine will sometimes hesitate (as if it's 'thinking' for a few seconds before allowing you to initiate a play.. because it's filled the 'random number table' and is re-initializing it for another round? I have always wondered about these periodic (after maybe around 30-50 pulls) 'hesitations' that slot machines exhibit; because my observations are that the pay/take characteristics of a slot machine seem to change between these 'hesitations.' Frequently, I have seen a slot that was in a 'pay cycle' (for lack of better words) go suddenly cold after going through this hesitation. Conversely, I have seen cold machines suddenly start paying more after this hesitation occurs. Whatever! The exact reason for this 'pause' it seems clear the machine is re-initializing or re-loading something.. I just don't know what it is.

No, the machine does not have a huge element table of over two billion elements. The random number generators choose each number once in the cycle using mathematical algorithms and do not need to keep track of which numbers were already chosen. Regarding the pause, it has nothing to do with how much it is going to pay. I think the game does some internal auditing from time to time. There is no such thing as hot and cold cycles with slot machines. The ups and downs are just normal random variation.

I play a machine in Atlantic city Called 'Reel Detectives'. I have read your informative article on how slot machines work and I have a good understanding of the programming behind them. what I don't understand is how on some days these machines will pay almost an exclusive combination of seven wins with no jackpots all day and yet other days it will pay jackpots all day with little to no seven wins.
If the machine is truly picking random combinations wouldn't the prize distribution be more random. It's as if IGT programmed the machine to have 'Planned Cycles' to make the game more interesting to play. I know your going to say that these are just random events, but it is extremely unlikely that a machine will only pay mid and lower tier prizes all day and omit the jackpot and vice-versa and do this over and over again. HOW are these WEIGHTED cycles explained? Also if you could point me to any books you recommend on the programming of slot machines I would appreciate it.

These are just random events. The laws of probability dictate that some days will be dry with a few big winners and others will have a lot of lower payouts. Most days will have a balanced mix and these days are always the first forgotten by the player. There is no switch the casino is throwing to alter the mood of their machines. I tend to think you're just remember what you want to in order to substantiate your theory.

Considering that a slot machines random number generator is fixed to supply the selected numbers to the virtual reel stops, and in turn are tied to the actual reel stops, is it not possible for the casino computers to swap non-winning stops to win stops, thus increasing the win percentage. This would maybe explain why all machines on some carosels seem to get hot at the same time, then all revert back after drawing a croud of players..just wondering..your site is a great information site..thanks

No, this does not happen. How much the slot machine pays is determined by a microchip called an EPROM, which is generally left alone. To change it, at least in Nevada, the casino would have to get permission from the gaming authorities. Even without permission, they would have to open up each machine and change the EPROM by hand.
I speculate that the reason for what you observed about all the machines on a carousel getting hot at the same time is due partially to chance, partially selective memory, and partially to a snowball effect where players will gravitate to an area where they hear a lot of winning and simply add to the number of wins because of more players.

Your explanation of virtual versus physical slot machine reels was most informative.

Given the random number generator stops on a virtual Cherry say, how does the machine make the physical reel stop on a visible cherry? I mean technically speaking.
Does this explain how pachinko machines from Japan can electronically alter payout percentages without altering the physical reel symbols?
Suppose the machine decides its time for a BAR, the only BAR on the third reel, just as one passes the pay-line. Does it let the reel go one full turn and catch it on the next go-round?
Suppose a physical reel stops on a paying combination by mistake, i.e. a symbol other than the virtual one pre-ordained. What happens then?

Black jack group group campground arizona usa. Thanks much.

Let me answer each question individually.

It is just programming code that dictates to the machine that if the virtual reel stops on a cherry to make the actual reel stop on a cherry. There are actual notches on the reels which may help the machine to stop in the right place. If you peer through the glass at and angle you can sometimes see these notches. However, I am not an engineer and am not sure exactly how the machine knows to stop at just the right moment. It just take it for granted that it can.
Theoretically, the casino could change the payout on a slot machine with just a remote control. The remote control could tell the machine to use any previously programmed virtual reels. Practically speaking, the major casinos need to get approval from the gaming authorities to change the payback of a machine. If they did get such authorization all a slot technician has to do is replace a chip inside the machine, known as an e-prom. This happens infrequently and would not warrant the expense of a remote control.
It seems to me the reels spin at least several times before stopping.
In the unlikely even that happened, then I think it would trigger a malfunction and the bet would be voided.

This happens to me 100% of the time: A slot will pay out normally to start and then after about a half hour’s consistent play, it will produce a declining win pattern, and an increasing lose pattern. Once I hit $20.00 in my account balance, the losing pattern will intensify to sometimes 20 straight loses in a row. (This is on a 5 reel, 9 line slot). I can almost sense when
