Slots are more of a game of chance, but there’s a math every gamer mustn’t ignore – the odds. Each game has a statistical probability against you winning. So, understanding the free online slot odds and their calculation will help you know the best games.

Unlike table and other casino games, slot machines run on Random Generator Numbers. The RNG generates numbers corresponding to free casino games symbols on its reels to give a win. Hence, you can’t manipulate slots results. Instead, winning combinations number, the payouts per combination, plus its Return-to-Player value all work together to determine any specific slot machine odds. 

Slot Machine Odds Calculator: How to Calculate

A slot machine calculator — is a web-based application that helps players accurately estimate possible profit or loss in any online slot. Unlike table games, slot paybacks or return to player (RTP) percentage varies, and it’s essential in calculating its odds. Slot manufacturers often publish their games RTP, and a little research will help to find a particular slot RTP.

Besides its RTP value, any slot machine odd calculator may need inputs like reels number and symbols to provide odds and potentially win or loss information. Also, since slots run on RNGs, the  results may differ slightly from its real online slot analogues. Each game has its own RTP percentage, it is important to try different options to find your favorite. For example, a wide selection of such free slot games on freeslotsHUB.com is available with no download, no signup, or no deposit.

Simplest Slot Machine Payout Calculator Example

Calculating a slot machine payout is an easy task. It’s simple math you can do effortlessly. Now let’s consider a slot machine with 3 reels and 5 winning symbols — Apple, Orange, Banana, Lemon, and Melon, plus a Joker. Assuming the winning combinations are such that 3 Jokers give 30 coins, any 3 Fruits give 10 coins, 2 Jokers give 4 coins, while one Joker ker gives 1 coin. By a simple slot machine payout calculator, the total number of combinations should be 6 x 6 x 6, which yields 216. However, the winning combination for individual symbols can be calculated as follows:

Landing three jokers will have one winning combination, which yields (1 x 1 x 1)= 1.

The Joker appearing on any two reels will give a combination of 

(1 x 1 x 5) + (1 x 5 x 1) + (5 x 1 x 1) = 15.

For the last condition, the joker appearing on any reel will have a combination

 (1 x 5 x 5) + (5 x 1 x 5) + (5 x 5 x 1) = 75.

Therefore, the total winning combination can be calculated as the sum of the individual winning combination. In that case, our slot’s total winning combination consideration as seen above will be 1 + 5 + 15 + 75 = 96 winning combinations. Calculating slot machine payout odds then requires you to apply another mathematical formula. This formula is expressed below:

= (Winning Combination X Possible yield) / (Total number of Combination)

You slot odds calculations for each symbol individually and then sum up your answers at the end. Therefore, such a slot machine will have a 99.53% payout rate, which is impressive. However, a real casino will not offer such a high payout rate. The average RTP for a high-paying slot will be between 94% and 98%. Talking about another slot game you can do it once by using a general summation as follow:

= (1 x 30 + 5 x 50 + 15 x 4 + 75 x 1) / (6 x 6 x 6)= 215 / 216= 0.99537.

Ways to Win and Pay Table: Odds of Winning Slot Machine

A PAR sheet contains all necessary information as far as possible odds of winning slot machine. One of such important information is the Pay Table and Ways to win. The paytable is a tabular section that includes all winning symbols combinations and the respective payout for the combinations. It represents the payout in terms of its bet options multiplier.

(Total Ways to Win)/(Total Ways) = 364/1000 = 36.4%

Chances of winning slot machines is a subsection under the line combination section that features the theoretical possibility of winning a symbol. It multiplies paytable’s payout to give its total payout for a specific winning combination. The paytable and slot machine winning chances representation on the PAR sheet are very important. 

The two representations are useful for calculating the hit frequency and the game’s RTP. Its hit frequency is calculated using total ways to win ratio to that of total ways and then multiplying by paylines numbers. The RTP can be calculated using its total payout ratio to that of total ways or combinations. Mathematically chances of winning slot machine, both are represented as follows:

Hit Frequency= (Total Ways to Win)/(Total Ways) x Numbers of Paylines

RTP = (Total Payout)/(Total Ways)

It will then be a slot machine probability calculator of each combination and probabilities summation to give you a total  RTP value.

Slot Machine Probability Tips to Look Out For

Slot is a game of luck, meaning you are prone to both possibilities of a win or loss. Slot machine probability then is winning chances of winning combination ratio to its possible combinations. Slot machine probability is different for different slots. While some slot machines have a relatively high probability due to their RTP, others have a low probability. 

It’s important to check out all slot machine probabilities before putting your money. Why? It determines your winning chances and, consequently, your returns. The following are slot probability factors you must consider;

Features of The Average Payout

The average payout gives you an idea of expected profit or loss when you bet a certain amount. For example, assuming you are willing to play with $100 bankroll on a slot machine with 90% RTP, you will have $90 average after your first spin. Continuing at the same rate ends up with nothing after 44 rounds. 

A slot machine with 98% RTP will give you 972 total pulls in 44 rounds if you bet $1 per spin. Interestingly, new slot machines design allows them to move faster between spins. Machines now use gaming card digital readouts to make spin as fast as possible. As a result, slots can now play up to 25 spins in just a minute. Going by this calculation it’ll bring 38.8 minutes to exhaust your $100 in 44 spins.

Slot Machine Probability Calculator: Math

Slot machine probability starts with calculating its possible combinations number. Start by multiplying symbols number for each reel. For example, a machine with 3 reels or 6 symbols will have (6 x 6 x 6), making 216 combinations in total. On the other hand, winning slot machine probability shows a 3-reel machine with 29 symbols will have (20 x 20 x 20) combinations, which gives 8000 ways.

So, you can calculate any online casino slot odds through the ratio of its winning combinations and its possible combinations number. Taking advantage of this formula helps you to establish hope in a game before you start playing. Interestingly, until you start using this formula, you may never know that big wins in some online slots, free spins games and jackpot are closely impossible due to their odds. 

Let’s consider slot machine probability of winning a 3 reel machine with a machine with 22 stops per reel and 4 reels and 32 stops per reel:

             32 stops, 3 reels: 32 x 32 x 32 = 32,768 combinations.

             22 stops, 4 reels: 22 x 22 x 22 x 22 = 234,256 combinations

Slot Machine RTP Calculator

The slot machine RTP calculator is another vital tool you must have in your slot machine tools collection. It doesn’t calculate odds but calculates RTP for a particular game. Slot manufacturers have been accused of shrinking games RTP, thereby causing players to lose more than expected. Game’s RTP is quite different from the player ‘s actual RTP while playing his game.

Sometimes, the difference in the RTPs can be 2, 3, or 5, which makes many players disregard the difference. However, using this slot machine RTP calculator, determines that it’s a big deal. Of course, an online casino or free internet slots game provider is responsible for informing the player of any changes made to the slot RTP. 

Let’s Consider an Examples:

  1. You’re playing with a $100 bankroll on a free internet slots machine with an original  96% RTP. Disregarding the volatility, playing at $1 per spin spin value, you’ll have $96 after 100 spins. Repeating this process, gives $92 after 196 total spin. Continuing with this process, by the time your bankroll falls below $1, you’ll have made 2476 spins.
  1. Now, let’s assume this slot’s RTP has been shrunk to 92%. Playing at $1 spin value gives $92 after 100 spins. Continuing the same process gives a bankroll below $1 after making 1238 spins in total. Considering the total game spin with 96% RTP and that of 92% RTP, there is about a 50% reduction in its total spin. This is how bad RTP shrinkage is and why a slot machine RTP calculator is a must.

Slot EV Calculator

EV is another word for expected value which is the possible profit or loss while spinning repeatedly. A slot is a game of luck which means either win or lose depending on your game outcome. Slots losing  chances are always higher than its winning chances. Therefore, spinning a slot machine repeatedly, causes both winning and losing outcomes. Your total possible win and loss at the end of several spins is called EV.

Slots EV calculator takes game bonus offers into consideration. This makes it different from the regular odds calculator. There are special calculators for slots EV calculator. Some recommendations are made below:

Creating PAR Sheets: Math Model of a Slot Machine

A PAR sheet is otherwise known as probability and accounting report sheet. It’s a spreadsheet-like format that defines the theoretical probability and payouts of possible combinations. A PAR sheet is created by free play slots for fun manufacturers and kept as a trade secret. However, some gambling researchers have in recent times sued providers for concealing such information stating that it’s against freedom of Information Act laws.

Example of free slot play online machine PAR sheet 

For every designed free online slot machine, there’s a PAR sheet. There is no standard format a PAR sheet must take, but it usually features the game’s probability and winning chances. Basically, a par sheet will include an RTP summary, volatility, hit frequency, reels number, paytable, and a lot of other game features that have to do with payment. 

International Game Technology Par Sheet Example 

PAR sheets are generally slot game providers’ trade secrets. It is very rare to hear about one in public. However, a PAR sheet belonging to an International Game Technology (IGT) provider was found in a publication called Casino Operations Management in  1988. It was the PAR sheet for 3 reel free online slot machines and 22 positions created in 1997.

The PAR sheet features a reel strip listing where the reels have been extended to 32 positions. It implies that certain positions of the original 22 positions were duplicated. This act allowed the slot to achieve an 85% payback which the provider originally aimed at. Interestingly, payback half point will only be achieved at 10,000,000 spins and this was at 90% according to its design.

Nonetheless, PAR sheets will not give tips about how to win slot machine free online games. It analyzes the payout pattern depending on the new number of combinations and game symbols. Unlike how odds information about certain free slot games like baccarat, video poker, and some table games might help you make a winning decision while playing.

Reel Deal: Payback Percentage, Meaning, Peculiarities

Every slot machine is designed to give players a bet percentage back. This rate is known as the payback percentage or as Return-To-Player percentage in most cases. The difference between odds and RTP is that while odds are calculated once, RTP is calculated over a long period of bettings. RTP percentage is estimated after several simulations of sometimes millions of spins.

For instance, if a free online slot games having 94% odds pays 9 times after 10 attempts, it’s easier to say that this slot RTP is 94%. The payback percentage is liable to change if there’s a change in the payout odds. The Gaming Board in various countries and Regulating bodies enforce that free slot games have an RTP percentage that exceeds 73%. Most free online slots machines have their payback percentage between 94 and 98%.
