Stopping Slot Machine Reels

broken image


If you can, insert a coin and pull the main lever on the outside of the machine. Look to see if this action affects the small horizontal bar above the reels. This bar is meant to detect whether a coin is in the escalator, and stop the reels from moving if there is not. On an old machine it could be sticky or stuck. Close the front door. Insert tokens into the Token Slot. Make sure the Credit Counter starts counting from the fourth token you put in. Note: Many of the newer machines require 3 tokens to be inserted for game play. The machine is ready to play. Press the reel spin knob. The reels will start spinning. Press the skill stop buttons to stop. The suspense created while the reels spin is a source of the excitement that the game provides. To lose this excitement is losing the very purpose for which online slots are played. In many slot games the reels come to stop sequentially with the first reel stopping first and the fifth reel stopping last.

You are playing a three-coin slot machine. You only are playing two coins at the time. The jackpot is hit. If you had been playing one coin, or if you had been playing three coins, would it still have gone off at that point?

If you had put in one or three coins the outcome would likely have been entirely different. The machine is constantly drawing random numbers and the numbers that were drawn at the moment you spin the reels determine the outcome. So, if you had played fewer or more coins you would have spun the reels at a different moment and thus the outcome would have been different.

Hey Shack I hadn't been to the site in awhile and I just wanted to compliment you on the new sleek look. I know you initially wanted to stay away from the banners but they do help pay the bills eh?
Congratulations also on the new gig with Casino Player, I enjoy it the site and your occasional posts on bj21. As someone who works in the industry, admittedly not slots, I was under the impression that the more recent slots have the RNG stop the moment the first coin drops, so it really doesn't matter if you play 1,2, or 3 coins -- the symbols will line up the same. Have I been misinformed? According to your previous answer I apparently have. Keep up the good work and I'll stay in touch, thanks and best wishes.

Thanks for the kind words Dave. You're right that it was the money that finally made me accept the banners. It is my understanding that when the player presses the button to spin the reels the random numbers are drawn at that instant, which determine where the reels stop, and ultimately what you win. The number of coins bet does not matter.

How many numbers does the RNG (Random Number Generator) pick for each spin in a slot machine? Is it three numbers (1 for each reel) or is it 1 number that's mapped to a unique combination of symbols for all 3 reels?
This is a great website!. FYI - A guy missed the Megabucks jackpot (7.9M) yesterday because he had just two coins in. To the best of your knowledge, when does the RNG stop and determine your outcome? If it stops on the first coin, then he blew it. If it is on the last coin, he could have had an entirely different outcome. My guess that the stop time is set by the individual manufacturer, and there is no regulation telling him when to do so. Just wondering if you knew different.

Thanks for the compliment. The outcome of the game is determined when the player initiates the spin. The game is constantly drawing random numbers, even when not played. The random numbers chosen at the moment the button is pressed to spin the reels determine where the reels stop, which determines what the player wins. So, if the player bet three coins he would have pressed the button at a different moment, causing a different outcome.

Have you noticed when you look sideways past the right reel on IGT games there are 4-5 counters inside the machine labeled 'coins in, coins out, jackpots' or similar wording? I was just wondering what your experience with the counters was. Is there any way to get helpful information from those? Thanks for your time.

https://softwareco.mystrikingly.com/blog/ez-tools-software-speakercraft. No, that information won't help you at all. Your odds are always the same on every spin, regardless of the counters.

I have heard it is illegal for a slot machine to deliberately have too many near misses. Can you tell me what you know about this?

To answer your question I asked a well connected gaming consultant and he said Nevada regulations state that one stop on a reel can not be weighted more than six times more than either stop next to it. So if a jackpot symbol were weighted by 1 and both bordering blanks were weighted by 6 then there would be 12 near misses for every one time the reel stopped on the jackpot symbol. This would be the maximum allowed near miss effect. My own results detailed in my slot machine appendix 1 back up this theory well. The red double seven was the highest paying symbol and I saw the blanks above and below it about 5 to 6 times as often:

Double Strike Actual Results

SymbolReel 1Reel 2Reel 3
Blank250248291
Double red 7525155
Blank259292262

The same source said that New Jersey and Mississippi likely have adopted the Nevada regulations. https://softhealthy.mystrikingly.com/blog/bitcoin-gambling-sites.

This is not a game theory question, but I figured since you answer dating questions you might handle this. I had a dream recently where I sat down at an open slot machine. I was getting my player's card out of my pocket when a guy came up from behind me and put money in the machine. I told him it was my machine and hit the cash out button and gave him his ticket. He said he had his eye on the machine and since he had his money in first it was his machine. I turned to call a slot attendant and while I was doing that he put his money in again, pushed the button and hit a jackpot. In my dream we then had an argument over who gets the money, the person who clearly had the machine and intended to play it or the person who unsolicited put the money in the machine. I realize this is a bizarre situation but who do you think would win the argument?

My understanding is that the person who is pressing the buttons gets the money. I asked Brian, who helped with the last question, about this. Here is what he wrote, which I agree with.

In the scenario described, the person who put in the money and pressed the buttons would receive the jackpot.

What I find interesting about this question is the paradox that in all likelihood, the jackpot never would have occurred without this chance encounter.

As you know, the random number generator in the slot machine is continuously working even when the machine is not in play. So even though one patron feels cheated, their run-in ultimately led to pressing the spin button at that exact millisecond when the RNG was on the winning combination. So, if one patron had acquiesced, there is never a jackpot to fight over. All no deposit casinos.

I have used your site to knock down myths and betting systems with many friends and your proofs always win the day. On the Pink Panther (and some others) there is a bonus round that presents a screen with pictures from which to pick. Behind some are coin amounts and others have a symbol that ends the bonus round. Once you are presented with the bonus board the placement of the symbols cannot be changed, can they?

Thanks for helping in the fight against betting systems. First let me say that I have never worked for a major slot machine company and don't have direct knowledge of this. However, I know many people in the industry and those I trust pretty much are in agreement on this topic.

That said, it is my understanding that in all forms of electronic games, including video slots, video poker, and video keno, the outcome is usually determined the moment you make your decision. Meanwhile the possible outcomes are constantly being shuffled, thousands of times a second. I can't speak for every slot machine but I believe that with the major U.S. slot makers the outcome is not predestined but depends on the exact microsecond you press the button to make your play.

First, love the site, very informative! Background: When using a Random Number Generator (RNG) to determine certain payouts for a finite set, such as 1 million lottery scratch off cards, the RNG can be programmed to drop non-pay or add pay selections so as to keep a more even distribution of winners throughout the finite set of cards created. The goal is to maintain a more even distribution in the cards along with the payout percentage as required. Is this, or can this programming be done in Nevada? The law of averages would indicate no need for this, but is it not theoretically possible for a signed 97% slot machine to payout 95% one year and 99% the next year unless some control on the RNG was made?

Thanks for the kind words. Scratch cards and pull tabs can indeed be printed in batches. These batches will have a specified number for each win, and the return of the overall batch will be exactly as the maker intended. In some jurisdictions, where only pull tabs are legal, the outcome can be displayed to the player on a video monitor, in the form of a slot or video poker machine. However, in Nevada, that is not how slots work. Each play is completely independent of the past. A machine programmed to average a 97% return, could indeed pay under 95% or over 99% over a year, especially if not heavily played.

I was wondering about the stop reels command on video slots - they look like they just stop the reels in their tracks, but that seems too risky. Is there some technique they use to create that illusion? Is it just change blindness?
The trick to poker is learning not to beat yourself up for your mistakes too much, and certainly not too little, but just the right amount.

You gotta remember that this is VIDEO slots you're talking about.
When you hit that 'stop' button, it is not the next three symbols on each virtual wheel that come to a screeching halt on the screen, but the three intended symbols that will suddenly be the next ones to roll down and stop.
OR, because they are spinning so fast that you don't realize it, they continue spinning for a partial revolution to the intended position.
Either way, the 'Stop' button changes nothing except the speed of the game.

Exactly.
The only thing that you actualy, 'Stop,' on a video slot machine is the random number generator, which occurs after you have pressed the, 'Spin,' button, or, 'Max bet,' or what have you. The reels, 'Spin,' for no reason other than effect. The video slot machine could instantaneously display the result of the, 'Spin,' without any actual, 'Spinning,' if it was programmed in such a way, of course, that would be far less entertaining.
I should imagine that the house loves players who believe in such a way, or use the, 'Stop,' button for any other reason, though. Given that such players are playing at a negative ER, it just means that they are losing their money faster. I'd prefer to get my money's worth by at least watching the full revolution of the, 'Spinning,' reels. I suppose the only exception to this is hitting the, 'Spin,' button after a result in, 'Free Games,' simply because I don't feel compelled to sit there and watch every single individual line pay on a small win. I'm also stopping the RNG (or it will stop itself after the line pays are displayed) during Free Games, and essentially playing the machine faster, but again, since I can't know what the RNG result will be, I'm just theoretically losing faster by not watching the Free Games play out on their own.
I've witnessed any number of players, 'Mash,' the spin button and get result after result and then complain about the machine, 'Never winning.' The funny thing about that is that such players will often be ahead, at some point, but they don't even notice because they are too busy mashing and waiting for the jackpot. I've even heard people say that the machine pays out at a better percentage as a reward for playing faster, which is patently ridiculous. It's a computer program, the payout percentages are pre-determined and are only affected by how many credits you bet.and that is only the case with a payout table that is not perfectly graduated!

I noticed on the slot machine 'Mystical Fortune' you can very easily predict the wild symbols on the last reel. If you see a run of cards and then hearts, touch the screen quickly and you have a very easy shot at having multiple wild symbols on the reel. You can observe and try this with different symbols on maybe the last 3 reels. Thing is, I don't think it makes much of a difference, if any. If you stop all wilds on the last reel, more than likely you wont have a winning combination. Fun to experiment.
It works pretty good in the free spins bonus though. The board flips over and I try it on the now 2nd and 3rd reels. FWIW, I believe the Rng hasnt stopped until you touch the individual reels. But I don't really know that, just a guess.

I doubt this is true. I think the moment you have hit the Spin button, the RNG is drawn. In my jurisdiction, there are signs saying you cannot alter the outcome of the game by pushing a 'stop' button. I think it only stops the reels earlier, which are just spinning for show, on the same spot they would have stopped on.

Usually, the wilds come up more often on the last reels since they're less likely to matter when they're over there. Are you sure you're actually making a difference? I'd expect the hit frequency of those symbols to be high to begin with.

That's exactly what I am saying. When you first hit, 'Spin,' you stop the random number generator and get the result. The RNG cycles until that point, it doesn't just hop instantaneously from one result to another, for instance, it doesn't decide the outcome of the next spin during the spin currently active.

Is it the Mega Line or the Five-Reels? That doesn't really affect anything, just curious.
The RNG stops when you hit the, 'Spin,' button. The individuals reels being touched does not matter in the slightest, you are simply expediating an already determined result.
Like RDW4Potus stated, you're going to see many Wilds on a reel that is typically inconsequential, or of minor consequence, regardless of the machine. To that extent, if that happens to be one of the reels, then you can, 'Predict,' that they will appear on every single spin and be correct much of the time.
QuickHits by the Slot Machine Gods at Bally Technologies is an excellent example of such a thing. The, 'Free Games,' symbols that come up are heavily weighted on the second and third reel and there are not as many on the fourth reel because you get a ding when you hit one on the second, then a louder ding on the second and third, and then the, 'Free Games,' if you hit one on all three middle reels. This is weighted with the intention of providing many, 'Near misses,' on the Free Games to keep the players spinning.and possibly encourage them to put in more money if they are, 'Close,' to getting Free Games within the last few spins of being tapped out.
It should also be noted on QuickHits that the most QuickHits symbols that can show up per reel are:
Reel 1: 1
Reel 2: 2
Reel 3: 3
Reel 4: 2
Reel 5: 1
The design is this way for a few different reasons. Here are the pays, assuming non-progressive:
3 QuickHits: 1 FOR 1
4 QuickHits: 5 FOR 1
5 QuickHits: 10 FOR 1
6 QuickHits: 50 FOR 1

7 QuickHits: 100 FOR 1
8 QuickHits: 1,000 FOR 1
9 QuickHits: 5,000 FOR 1
---
The most common way to see the QuickHits is one or more on the third reel. This accomplishes a variety of things in terms of player retention:
1.) It keeps the QuickHits results visible. Though we read from left to right, a player's attention is largely going to gravitate to the center of this machine because the Free Games can only be had if reels 2-4 have a Free Games symbol, and again, the majority of your QuickHits are going to show up, by necessity, on reels 2-4.
-It's better the player not look at the first reel, anyway, it's largely a mixture of Wilds and low-paying symbols. The high-paying symbols are heavily weighted to the fourth and fifth reel. There are quite a few on the second reel, as well, but not as many high-paying symbols on the third. The third reel is largely low-paying symbols, and of course the QuickHits and Free Games symbols. There are a few Wilds on the third reel, but not many.
2.) If the player hits Three QuickHits on the third reel and nowhere else, (one of the most common ways you will see QuickHits) then no other win can possibly be had because it pays 1 FOR 1 and prevents any other paying result from happening. At the same time, however, the player is happy to see three QuickHits and, much as is the concept with Wilds and Bonus Games, will be led to believe that more are coming.

-It's funny because I imagine that if you had alternating results of not other than a losing result followed by three QuickHits down the middle, a player would reach for another $50 after losing $50 at a rate not even close to approaching the expected return!!!
3.) You could have one-two QuickHits show up on the third reel (absent any other QuickHits) and they might serve as a, 'Line blocker,' on what, if completed, would have been a pretty decent payout. In these instances, the players will be compelled to feel as though they were, 'Really close,' to hitting said decent payout. The Triple Blazing Sevens QuickHits machine is an excellent example of having a line blocked by the third reel. The best part of that machine is that many players don't really differentiate between the Single-Double-Triple Sevens very well and just figure that a line of Five Sevens kicks ass. It doesn't, but it compels many players to think they've had even more, 'Near misses,' on good payouts than they have actually had.
4.) The Free Games symbols, if only one-two of them, can also serve to block lines and make players think they had a close, 'Near miss,' on decent payouts. In addition, if you get one on the second reel and one on the third, but not the fourth, many players will be compelled to think more are coming!
Great machine.
I've never played Mystical Fortune. If I happen to notice it and remember, I'll stick a $5.00 in a penny one and play one line at $0.01/line for you and figure out what the player retention angle is and let you know. Video Slots must be compelling, above all, so there is ALWAYS a player retention angle.

The game I was talking about is here: http://www.youtube.com/watch?v=giv8jhzwbyA
That's just a link to the bonus round. The game has 6 reels. And 180-200 lines.

Reel Slots Free

I am sure that I'm purposely stopping the 6th reel on the string of wilds. But it just won't matter because the game's winning lines won't reach all the way to the 5th or 6th reel. It's super easy to do on the last reel and not so easy to do on 5th reel. On the 4th reel you can do it but it's pretty tough. On the 4th reel I believe that the 'trigger string' of cards then hearts appearing also has a 'false trigger string' of those symbols that doesn't have a string of wilds following it. (instead it follows with a string of ring symbols.)
The thing is though, has the rng already stopped during the free games? Is your payout already decided?

There are places where slot machines must require skill. These are typically gray machines in bars and gas stations trying to skirt laws to become an amusement game under Dave and Buster or Chuck E Cheese laws in states without casinos. Virtually all real casinos are going to have slots that cannot have outcomes changed by a stop button.
Harrah's Cherokee is the only casino I can think of that has (or had as I have not been there in years) slots that require(d) skill or could have skill change the outcome of a spin. They had to make their slots play that way so that the machines would fall under the existing NC video poker laws at the time that their license was based on, a law that has since been repealed.
