Aside from basic strategies, did you know that volatility is another gambling variable that highly affects your slot gaming or other online casino games? In essence, volatility refers to the frequency of wins and risk of your slot. How can you maximise it to improve your chances of getting higher returns for your bankroll? Learn more about it here at Bitcasino.
Online slot volatility: What is it?
Slot volatility determines your likelihood of landing winning combinations, the payout sizes and the level of risk when you’re playing an online slot or physical slot machine. It also measures the frequency at which a casino game rewards players with a winning payout over time.
There are three variances ranging from low, medium and high. Knowing a game’s volatility allows players to choose which slot games fit their budget and risk tolerance.
Slot variance vs slot volatility
Many people confuse online slots volatility with variance at first because both deal with slot gameplay and results. Here's a definition of slot variance to clarify and differentiate between the two.
Variance refers to the distribution of winning combinations over the long term. Simply put, it measures how the average results can change instead of volatility, which shows players how often and big the payout is.
Additionally, volatility measures the time the slot is played, while variance deals with the allocation of the rewards you can receive while playing.
To better understand slot variance, here’s a table which shows the levels of variance and their descriptions:
Variance | Win Frequency | Win Sizes | Description |
High variance slots | Rare | Big | high risk, high reward |
Medium variance slots | Average | Average | average risk, average reward |
Low variance slots | Often | Small | low risk, low reward |
What are the different volatility level slots?
The different volatility levels range from low to high and can fit players with various risk appetites depending on their preferred gameplay styles. Knowing the levels of volatility also determines the games’ win-loss ratio, which helps players like you choose games to place bets on to get more wins.
Low volatility slots
This type of slot volatility is associated with a low-risk play style, with regular payouts and small wins throughout the game. Players who consider themselves more conservative and risk-averse are best for this type of slot. In addition, players with a tight bankroll can benefit greatly from low-volatility slots since they have more regular wins.
Medium volatility slots
Medium volatility slots balance more game features and small to average winning combinations throughout the game. Usually, these games have more bonuses attached to their mechanics and have decent multipliers and free spins.
Players with a moderate risk appetite and a healthy bankroll will most benefit from playing medium volatility slots.
High volatility slots
Players who are risk-takers will like high volatility slots since they are the riskiest but provide big jackpots. However, these are rarely triggered, so these slots are considered high-risk and unpredictable.
Typically, these games also have bonus features such as wilds or free spins that can impact the overall wins of a player. To better understand volatility, here’s a table which shows the levels of volatility and which types of players they suit best:
Volatility Level | Type of slot player |

Why is slot game volatility essential to know?
Here are the benefits of knowing a game’s slot volatility:
Slot game volatility helps you make informed choices
Slot games were traditionally seen as a game of pure chance, where no amount of skill and technique can determine if you’re going to win or lose money. That perception has changed over recent years, with more players analysing their games and improving slot machine strategy.
This doesn’t mean that slot games are predictable, but rather, it means that players can make better choices, like choosing when to play a maximum bet on slots or assessing their risk tolerance.
Builds game provider credibility
Game providers are the ones that determine a game’s volatility because they design the mechanics of the game. For players, knowing that a slot game has volatility eases their concerns over fairness and lets them test the RTP to see how closely they match up.
Setting your gaming budget
Knowing the game’s volatility is crucial to setting your gaming budget and determining your playing style. As mentioned, low volatility levels are best for those with a conservative style of play and a tight bankroll, while higher volatility slot levels are best for those who can afford to spend and risk more.
Players of all experience levels should set their budget and how much they will spend in one night. This is especially true for pro casino players who must manage their bankroll during a tournament season.
It sets players’ expectations
Knowing the volatility allows players to gauge how much they can win or lose in a particular game and help them set their expectations and how much money they want to wager.
What is RTP in Slots?
Return-to-player, or RTP, is the ratio of a player’s wagers into a game to the amount they receive from it over time. Usually, a high slot game RTP means the player has a higher chance of returning their bet.
Since modern online slots accept crypto and fiat money for betting, it has made it easier for people to record their winnings and losses from a game to calculate return-to-player slots.

Slots RTP and Volatility: What’s the difference?
We’ve established the difference between volatility and variance, and we’ll do the same with RTP and volatility because these terms are often confused. Many people interchangeably use RTP and volatility when referring to a slot game’s chances of paying out.
Players can often see the RTP and volatility together in a slot game's description alongside the features, paytable and available bonuses like free spins or multipliers.
RTP is the figure expressed with a % sign and is the ratio of the bet size versus the amount received over time. In comparison, volatility refers to the risks involved in making a bet, the frequency of wins, and how big the payout will be.
How to determine the volatility of a slot machine?
Determining the volatility of slot games is easy! It is often provided in the game stats board at the online casino platform you are playing at. But if you can’t find it, you can try any of the options below:
RTP average
RTP and volatility can be linked directly since RTP exhibits the amount of your wager you can win back while volatility is the risk or number of times you can win.
The games that have a high RTP percentage often have a low volatility rating since the game pays out often and you can win back most of your bets. The same thing goes for high-volatility games who often have low RTP percentages since the game doesn’t payout as much.
Fun mode
Another thing you can do is observe the game. Switch the slot to fun mode and spin the reels. The game has low volatility if it often pays out, but if it pays out high rewards, then it’s high volatility.
Fun and rewards in every volatility
