Slot machine jackpot return rate calculation for Jackpot

The actual psychological application of slot machines is different from baccarat, as long as the slot machine design is in line with this principle, basically the slot machine is eating people without spitting bones.

But why do slot machines always work miracles?

It is because of the spitting model of slot machines.

The first thing you need to do is to get a good idea of the rate of return of the slots: usually, the rate of return of the slots of the mainstream platform is between 80% and 98.5%, such as the AMEBA slots, people in the rules of the game, the return rate of the game is clearly marked. So, basically, this is not falsified, of course, do not exclude some slots have loopholes, and fishing games, etc., have had such loopholes. In addition, AMEBA’s free games and so on these do not say much.

If there is such a return rate, why are there still many people who die miserably and cannot make this so-called return rate?

In fact, the amplitude problem.

And baccarat is different, baccarat amplitude we all the same, while the amplitude of the slot machine is for each person, or each account, and even some models inside is for each time period.

The general estimation of slot machine scores to determine a basic consensus method is: play how many how many hands (specific depending on the type of machine) to see if it is out of the score, if there is a certain score to play how many how many hands, and then look at the score to make a judgment.

This method is basically correct, but there is a drawback that it is not very accurate. Just because it is taking more hands does not mean that it will not put up a bigger score next. Conversely, just because it is releasing more hands does not mean that it will definitely release a larger number of points. My algorithm is to use only 1 point to calculate the theoretical return rate for the next round (or the current round) more accurately. That must first be proved theoretically to work, otherwise it is only an estimate judgment.

Before we start the mission, we would like to make a statement.

  • The calculations are all based on the current GLI casino equipment standards for Macau casinos. If a Macau casino does not currently use this standard, then none of our algorithms will be valid.
  • If our understanding of the GLI casino equipment standard is incorrect, then our algorithm for the corresponding error is not valid.

Slot machine design problems

1.Chance of winning

Slots are usually not very good at winning. Casinos make money because they keep a certain percentage of their winnings. The rest of the winnings that are not held back are lost to the players in the form of random odds. Slot machine odds are based on a spin of thousands and millions, which means that the outcome of each game cannot be predicted or calculated, and just because a player wins big from a slot machine today does not mean that something will happen on a given day in the same casino, each win is a separate occurrence.

Slots are profitable because they have a built-in program that allows players to win only a portion of their winnings. The slots are designed and tested to ensure that they do not lose money.

Slots are designed to pay out 80% or more of the total winnings, which means that the casino can make up to 20% of the winnings from each slot machine. However, not all slots are set at the same percentage, and the same game can have built-in payout percentages ranging from 80% to 95%, as long as the versions are designed differently.

However, since these different versions of slots all look the same, players have no way of knowing the payback percentages of individual slots. While it is possible to calculate the odds of winning and losing in general gambling games, slot machines do not provide the information needed to let players know.

2.Game speed (short play speed)

Slots are usually played faster than other games, so people who like them will lose more quickly. Slots offer a continuous gambling experience where players can bet up to 600 to 1200 times per hour.

3.Weight reel

Most gamblers are unaware that the reels of slot machines are weighted, so the patterns of small wins appear more frequently than the patterns of large wins. Casinos cannot use unevenly weighted dice or stack a lot of cards on top of each other, but weighted reels are common in slot machines and most players are not aware of this.

4.Uneven scrolling

An uneven reel means that some reels have fewer jackpot patterns than others. In this case, the chance of two jackpots appearing at the same time is much higher than three jackpots appearing at the same time. In this case, it is easy for players to have the illusion that they are just a little bit closer to winning.

When the reels are spinning at high speed, players seem to see all the patterns and think they all have the same chance of appearing, but that’s not true because they don’t even know that one of the reels is missing the winning pattern.

5.Fake win

Fake wins are when players win less money than they put in. Although players are still losing money overall, the slots will treat these moments as wins and play music to create an atmosphere where players can easily get the illusion of winning.

6.Winning by a margin

A near win is when the jackpot pattern appears above or below the winning line, as if it is just short of winning. Most players really believe they are close to winning. The truth is, a loss is a loss. Just because a pattern appears above or below the win line does not mean that players will win the jackpot anytime soon.

However, studies have proven that point spread wins give players an incentive to keep betting because they feel they will win soon. In Macau, casinos can legally program their slot machines so that the spread wins occur twelve times more often than they would naturally.

7.Stop button

The stop button gives the players the illusion of control, but in reality the button has no effect on the outcome. The moment the reels start spinning, the result is already determined and the game is over. In other words, when the player presses the button, the winner is already determined, but the result is only displayed after the reels have spun for five to six seconds. 

8.Token Points versus Currency

The moment a player puts money into a slot machine, the currency automatically changes to tokens, and while players are focused on how many points they have left, they often forget how much money they actually bet.

This can cause players to overspend. Players need to convert their tokens to currency to know how much they have really spent. In Macau, many slot machines display the total amount wagered, but the position and size of these display cards are difficult to see.

9.Win small

When playing slot machines, players may experience frequent small wins. These small wins are not enough to make up for the total amount lost, and the winnings are usually wagered back into the game, for example, if players start with $100 but end up wagering more than $100 because they continue to wager the money from the small wins.

Just like a false win gives players the illusion that they are doing better than they really are. By the same token, players who experience a small win can easily become delusional and believe that continuing to gamble will make them win the jackpot. In fact, continuing to play will usually cause them to lose even more money. In contrast to the average person who stops gambling after hitting the jackpot, small wins encourage players to keep gambling.

10.Encourage maximum bets

Did you know that players can bet up to three dollars per game on one line slots? This is because in a multi-line game, players can choose to bet more than one line at a time. Usually, the slots themselves encourage players to make multi-line investments.

Slots are one of the most popular and potentially most damaging forms of gambling in the world. There are approximately tens of thousands of slot machines in Taiwan alone.

When it comes to gambling problems, players’ attention is often focused on the gamblers, but more importantly, the games themselves can also lead to various gambling problems. Take slots for example, the ultra-fast game speed and the design that promotes illusionary graphics often mislead players into thinking about slots and create a lot of problems. It would be helpful if players of slot machines were aware of the risks associated with these designs.

The scoring procedure requires that the theoretical return rate must reach a minimum return rate (e.g., a set return rate of 75%) during each round of the expected base game progression when the player is consistently at a non-linear odds minimum bet

For example: suppose a new machine, its return rate is set at 80%, the first person to play the first round (assuming 100 hands), it ate 1000 points, put 700 points, only reached 70%, the second person to play the second round (assuming 100 hands), it ate 1000 points, put 900 points, then the theoretical return rate will only reach 80%.

That is to say, if the person in front of you loses, the person who plays after you will still lose. However, if the first person plays the first round (assuming 100 hands), he eats 1000 points and puts 500 points, which only reaches 50%, and the second person plays the second round (assuming 100 hands), he eats 1000 points and must put 1100 points, then the second person must win, right?

The program is not like this, the actual situation is: for example, the first person to play the first round (assuming 100 hands), it ate 1000 points, put 500 points, only reached 50%, the second person to play the second round when the program called the number of hands in the second round may be 200 hands, it ate 2000 points to put 1900 points, so that the total number of points eaten in 2 rounds is 3000 points, the total number of points put for 2400 points, the return rate of 80%.

Still, if the person in front of you loses, the person who plays after you will still lose. Only in the first round of the return rate is very low in the case of the last round can appear high score.

Therefore, it is necessary to play 2 rounds with 1 point during the trial. In order to guarantee the chance of winning money by playing machines with high theoretical return rates, it is recommended that you only play with a full line of 1 point when you try to get a high theoretical return rate.

The score of the machine is related to the number of lines of the machine (20, 25, 50 lines models), i.e. the more lines the deeper the limit of the machine, the higher the score.

According to the current situation of the fight

If a 20-line machine plays 400 hands with 1 point and doesn’t score 4,000 points (or doesn’t score two 2,000 points in a row soon) or so, give up. This is a machine with a low theoretical return rate. If you get 4,000 points (or 2 consecutive 2,000 points) or so, play another 30 or so hands with 1 point, starting from the 40th hand to 200 hands and playing 20 lines with 1 point until you get 4,000 points (or 2 consecutive 2,000 points) or so.

The 25 line (25 points for a full 5 lines) machine is played with 1 point for 500 hands, and if you don’t get 5,000 points (or if you don’t get 2 consecutive 2,500 points), you give up. If you get 5,000 points (or if you get 2 consecutive 2500 points) or so, play 40 more hands with 1 point, starting from the 50th hand to 250 hands with 25 lines and 1 point until you get 5,000 points (or if you get 2 consecutive 2500 points) or so.

If a 50-line machine plays 1,000 hands with 1 point and does not make 10,000 points (or does not make 2 consecutive 5,000 points), then give up. If you get 10,000 points (or if you get 2 consecutive 5,000 points), play 90 more hands with 1 point, starting from the 100th hand to the 500th hand and playing 50 lines with 1 point until you get 10,000 points (or if you get 2 consecutive 5,000 points).

The new slots are not the same as the new slots, but they are the same as the new slots. This should be of some help to companies that are just starting to operate slots in terms of line selection. Most slot machine companies, if they are new to the game, should not be scared by the short-term losses.


Slots are a huge source of revenue for casinos, and the game is designed to keep players playing and maximize profits for the operator. Some features of slot machines are often designed to mislead players into believing that their chances of winning are greater than they actually are. Players need to understand that these games are designed to bring excitement to some, but at the same time mislead others and cause problems.

Slot machine games have been very successfully transformed into online games because they are inherently well suited to the requirements of online gaming. Online, players can choose from a wide range of games with higher payoffs and relatively lower win rates in casinos.

Players can also find the most lucrative slot machine jackpots online, often winning hundreds of thousands of dollars in a single jackpot.
