Maths Odds in Slot Games

Have you ever played a slot game and wondered, "what are my odds of winning?". In the world of betting and gambling, we all want to know the odds. We often think it's the luck of the draw as to whether you win – but there is a science behind it.

A classic 3-reel online slot is one of the most popular options for slot games. Online slot machines control the odds of you winning through several factors, most of which are out of your control. The payment that slots payout will depend on volatility and the game's RPT (Return to Player) rate. The payout from slot machines will always be different with the odds changing depending on the slot you're playing.

This guide takes you through the general maths odds in slot games to help you understand your odds and probabilities when playing slot games. Generally, the odds of playing slot games are rarely – if ever – in the player's favour but being aware of the odds can help you make an informed decision.

Slot machine odds vs. Table games

Every casino game comes with a house edge, meaning that the casino has an in-built advantage against the player. It ensures that the casino can earn money in the long term over games. What makes slot games different from other games, such as table games, is that there's no way for the player to try to manipulate the odds.

When you play table games online, such as blackjack, you can influence the odds of winning. You can apply a strategy or choose the right bets to give you better odds of winning. There are some statistics that you want to keep in mind – like the fact that casinos are more likely to win if you're playing roulette with single number bets. Alternatively, your winning chances go up if you play roulettes where you’re betting only on the red and black.

These odds are more in the player's favour as it allows you to choose a strategy and decide how to play, allowing them to improve their odds. Comparatively, this is not how slot games operate.

However, this maths assumes that you're planning through an online casino that is licensed and operates games that are certified as being fair by a third-party independent company or international authority. The best way to get fair odds on a casino game is to play on a genuine and legitimate casino game.

Random number generators

A classic 3-reel online slot operates through a random number generator. When you play the slots, it sets the machine in motion with the system generating a random combination of numbers or symbols on the screen. You’ll need to keep this random symbol combination in mind when considering the odds for online slot games.

Random number generators are used to ensure that every spin is treated as being independent, making sure that a previous spin has no impact on the outcome of the next. Several elements come into play when determining the probability of winning a slot machine game.

You'll have to consider the number of reels, how many symbols are on each reel, and the active pay lines on the game. The pay lines are important as some slow games give you the ability to manipulate these elements by giving you control over how many pay lines and reels you want to play.

It's worth considering that while more reels and pay lines will boost your probability of winning, it'll also increase the cost of your bet. It may seem that it's impossible to beat the odds of a slot machine, but there are some techniques that you can use to increase your chances of winning.

The probability of winning on slot machines

Anyone can work out the number of combinations possible for a slot machine. You’ll need to multiply the number of symbols by each slot. If you have a three-reel machine with six symbols, there is a possibility of 216 combinations. Similarly, a three-reel slot machine with 20 symbols in each slot gives you 8,000 different combination possibilities.

You can calculate the odds of winning on the slot game by dividing the number of winning combinations by the number of possible combinations. This study gives you an insight into how the probability of slot games we see today, were first created and given probability odds.

A theoretical approach to playing slot machines

When you understand the probability behind winning on slot machines, it's easier to take a theoretical approach when playing slot games. While winning at slots is not a given, you can increase your chances of winning by understanding how the odds work.
