When playing slot machines at casinos, most players would normally like to know which denominations are most promising in order to find the machines that offer the best return rates.
All VGM's offer standard slot machine-type games, plus keno in denominations from five cents to $10. The machines all accept cash but do not pay out in cash.
Normally, the higher the denomination, the better the return rate. For example, a denomination of 0.05 features an average payout of 92.5%, while a denomination of 5.00 offers a return rate of 98.4%.
Greater revenue is generated by casinos by getting a large monetary turnover. Normally, a smaller amount of money will be generated by the slots with a 0.05 denomination on a daily basis in comparison to those with a 1.00 denomination for the same period of time. More money is generated with the help of higher-denomination machines, which is why most casinos can afford to offer higher payout rates to players.
Slots Machines Odds of Winning
Basically, slot machines are among the casino games that do not allow for a successful winning strategy to be implemented. Unlike games of skill, like poker for example, where the player can use a strategy or at least have realistic expectations, slots are designed specifically to make this impossible.
There is practically no way to come up with a long-term winning strategy for slots because the outcome is based on chance. Also, slot machines have lately become more complex, which is another contributing factor that eliminates even the slightest possibility of making a prediction or using a strategy to deduce the results. As already explained, the paylines of every slot machine are controlled by a Random Number Generator or RNG, which guarantees that the winning combinations occur at random.

The randomness of a slot machine can be tested with special software, which examines the return to player over prolonged periods of time, involving hundreds, thousands, and even millions of spins.
The house edge, on the other hand, is another factor that prevents players from coming up with a winning strategy. Some specialists say that players should not be betting for the sole purpose of generating massive returns when there is a house edge. Of course, the player might prefer to bet simply for enjoyment while knowing that there is a small possibility to generate a winning. Undoubtedly, there is always a chance to get unexpectedly lucky and hit a winning combination.

If the player wonders what is the exact edge of a given slot machine, they should be aware of the fact that normally there is no way for them to find out. It is against the casino's interests to publish such information, which is why there are very few players that actually realize there is a real house edge.
If the casino has published the Return to Player percentage (RTP) of your slot of choice, you can use this to calculate the house edge by subtracting the return from 100%. For example, if a given slot offers you a return of 97.54% on average, the house advantage you are battling would amount to 2.46%.
How to Estimate the Odds?
Slot Machine Odds Of Winning
As was already mentioned above, in modern slot machines, the odds of hitting a certain symbol or a combination of symbols depend on the settings of the reels. The work of the reels, on the other hand, is controlled by the software plus the Random Number Generator (RNG).
Making an attempt at getting the odds of winning at a certain slot machine is a hard task. First, there is a great diversity of slot games available on the market, which basically means that the odds may vary a great deal.
Still, the odds against a certain machine are usually expressed as a payback percentage. Logically, the closer this ratio is to 100%, the more money the machine would return.
It may sound unbelievable, but there are some machines that even offer positive expectations, which means there is practically no house edge to deter the player from accumulating profits over the long run. These slots are usually called “loose” and are often scattered in specific places on the casino floor to attract more players. This was exactly the reason why most casino operators used to put the loose slot machines near high-traffic areas such as bars, entrances, and so on.

Slots odds are the probabilities of getting a winning combination on the reels. They depend on the type of slot machine you play. Originally the odds were very easy to calculate as the only thing the players had to consider were the number of reels and the symbols used on each of the reels. As a result, the 3-reel slot machines are traditionally believed to be better for player's winning chances, and thus the more reels and symbols on them, the lower a player's advantage.
How to Calculate Odds
The odds of getting any combination on the slot reels are easy to calculate if you know the number of symbols used on each reel. Let's take a closer look at the odds and consider an example:
If you have to make a line of 3 diamonds on one payline to win the jackpot, it is most likely that each reel has only one diamond symbol on it. If the machine is a 3-reel one and there are 20 symbols on the reels, the chances of hitting this combination are:
Possible combinations on the reels: 20 x 20 x 20 = 8000. The odds of getting this combination are 1 in 8000. For a 5-reel slot machine the chances are even less: 20 x 20 x 20 x 20 x 20 = 1/ 3,200,000 (1 in 3,200,000). The slots probabilities are usually shown as a percentage, so for 3-reel and 5-reel slot machine with 20 symbols on each reel we have these probabilities:
However, the number of symbols on the reels can differ from machine to machine, and that is why the slots odds are different. Here we look at some more examples of slot machines containing 3 and 5 reels each with different number of symbols on them - for these examples: 20, 22 and 25.
| Slot Machine Type | Number of Symbols | Number of Combinations | Odds | Probabilities |
| 3-reel | 20 | 8,000 | 1 in 8,000 | 0.0125% |
| 22 | 10,648 | 1 in 10,648 | 0.0093% | |
| 25 | 15,625 | 1 in 15,625 | 0.0064% | |
| 5-reel | 20 | 3,200,000 | 1 in 3,200,000 | 0.0003125% |
| 22 | 5,153,632 | 1 in 5,153,632 | 0.0000194% | |

Slots Payback Percentages
The slots payback or return is the amount of money the slot machine pays out as winnings, against the total number of credits wagered by players. The payback is always shown in percentage.
The main idea behind counting the odds in slot machines lies in understanding how the machine pays out money. Unlike what many people believe, not everything is random in a slot machine. Slots are programmed to pay out a certain percent of the money put in with each play.
For example, one machine may pay back 80% of bets while another one may pay back 91% and even 100%. This means that for every dollar put in the machine the casino takes 9 cents and pays out 91 cents. But it does not do it for every dollar put in, it just pays out explosively and this is what makes the game so great.
You must remember that there are two basic types of slot machines. These are:
- Loose slots are slot machines that are programmed to return 82-98% of the wagered money, or even more if you play slots online. As a rule, high-denomination slots pay out more than those offering, for example, $0.05 or $0.25 bets. For more about typical paybacks on different slot machines please read the strategies page.
- Tight slots are machines that pay out less than 80% and sometimes down to 50% of the wagered money. To avoid playing at these slot machines try not to gamble in motels, airports, bars, gas stations, etc. The payback percentages vary from casino to casino and that is why it may be difficult to find the best machine in the gambling hall.
