When playing slot machines, two key terms you should know are RTP (Return to Player) and volatility. RTP shows how much money a slot pays back over time, while volatility tells you how often and how big the wins can be. Knowing these helps you choose games that match your budget and style.
What Does Slot Return to Player (RTP) Mean?
RTP, or Return to Player, is a percentage that reflects the amount of money a slot machine will theoretically pay back to players over an extended period of time.
RTP gives players an idea of how much they can expect to win back over many spins, but it’s important to remember that this is just an average.
For example, a slot with an RTP of 96% will return 96 cents for every dollar wagered over a long period.
The RTP percentage of a slot game can vary significantly, with most modern slots falling somewhere between 85% and 98%.
A higher RTP means better chances of winning in the long run, but results can still change from spin to spin. The actual return can fluctuate from one session to the next, as slots are designed to be random.
What Does Slot Volatility Mean?
Volatility, also known as variance, refers to the level of risk associated with a slot machine. It indicates how often and how much you can expect to win while playing a particular game.
Volatility is a measure of the unpredictability of a slot’s outcomes. Essentially, it tells you whether a slot offers frequent small wins or infrequent large wins. Understanding the volatility of a slot is key to determining whether it aligns with your personal playing style and risk preferences.
There are three main types of volatility in slot machines: low, medium, and high.
Common Slot Terminology – Easy Guide
| Category | Term | Meaning |
|---|---|---|
| Basics | RTP (Return to Player) | Shows how much money the slot gives back to players over time. 96% or more is good. |
| RNG (Random Number Generator) | Makes sure every spin is random and fair. | |
| Volatility | Tells how often and how big the wins are. High = big wins, less often. Low = small wins, more often. | |
| Variance | Similar to volatility. Low = frequent small wins, high = rare big wins. | |
| Jackpot | The biggest prize in the game. | |
| Progressive Jackpot | A jackpot that keeps growing with every bet until someone wins. | |
| Game Play | Reels | The spinning columns with symbols. Most slots have 3 or 5. |
| Payline | A line where matching symbols must land to win. | |
| Ways to Win | Some slots (like Megaways) offer many ways to win without fixed lines. | |
| Spin | Press the button to start the game. | |
| Bet Size (Coin Value) | The amount of money you bet per spin. | |
| Autoplay | Lets the game spin automatically for several times. | |
| Multiplier | Boosts your win (e.g. 2x means double the money). | |
| Special Features | Wild Symbol | Like a joker – replaces other symbols to help make a win. |
| Scatter Symbol | Can give free spins or bonuses even if not on a payline. | |
| Free Spins | Extra spins that are free of cost. | |
| Bonus Round | A mini-game inside the slot with more chances to win prizes. |
Correlation between volatility and RTP
RTP (Return to Player) and volatility are two important but separate aspects of slot games, and they do not have a direct correlation.
RTP tells you how much you get back over time. Volatility tells you how the wins are spread out – frequent and small, or rare and big. They work together to shape your playing experience, but one does not control the other.
So, RTP and volatility are not directly linked. A slot can have:
- High RTP + High volatility – Pays well over time, but with long dry spells and rare big wins.
- High RTP + Low volatility – Pays often, but in small amounts.
- Low RTP + High volatility – Riskier, with fewer chances to win and lower returns in the long run.
- Low RTP + Low volatility – Frequent small wins, but overall low return.
Types of Slot Volatility
When choosing a slot machine, understanding the different volatility types can help you decide which game best suits your play style.
Let’s break down the various types of volatility in more detail.
High Volatility Slots
High volatility – big wins, but less often.
High-volatility slots are often the most thrilling and exciting, offering players the chance for large payouts. However, the risk associated with these games is higher.
High-volatility slots may have long stretches where you don’t win anything, but when you do hit a win, it’s typically a substantial one.
Who’s the right fit:
These slots are ideal for players who have the patience to ride out the dry spells and are looking for the thrill of a big payout. Since the risk is higher, the potential for reward is also greater.
Medium-High Volatility Slots
Medium-high volatility slots offer a balance between risk and reward. Players can expect somewhat frequent wins that are typically higher than what you might find in a low-volatility game.
However, the risk is still noticeable, as the payouts aren’t as consistent as in medium-volatility slots.
Who’s the right fit:
These slots are great for players who are looking for a mix of excitement and reward, without being too extreme in either direction.
Medium Volatility Slots
Medium-volatility slots are the sweet spot for many players. With these games, you can expect a balanced mix of frequent small wins and occasional larger payouts.
Who’s the right fit:
These slots are perfect for players who want a steady stream of action and aren’t looking to endure long periods of dry spells.
Medium-volatility slots are typically recommended for players who enjoy a more moderate level of risk and don’t want to wait too long for a payout.
Low-Medium Volatility Slots
Low-medium volatility slots offer smaller, more frequent payouts. The risk is lower than medium-volatility games, but so are the rewards.
While the wins aren’t as large as those in higher-volatility games, the steadiness of the gameplay can be very appealing for players who prefer a more relaxed experience.
Who’s the right fit:
These slots are best suited for players who prefer a less risky experience and are looking to make their bankroll last longer.
Low Volatility Slots
Low-volatility slots are the most predictable and consistent, with small wins coming often. While the payouts are smaller, they occur regularly. This makes low-volatility slots ideal for players who prefer stability and don’t want to deal with big swings in their bankroll.
Who’s the right fit:
If you’re playing for fun and don’t mind smaller wins, low-volatility slots can provide a pleasant and low-risk experience.
Types of RTP in Slots
RTP comes in different ranges, and understanding the variations can help you find the right slots for your style.
High RTP Slots: Pros and Cons
Around 96% or higher
High RTP slots are often appealing because they theoretically offer more frequent payouts over time. With RTPs around 96% or higher, these slots promise a better long-term return.
However, the downside is that high RTP slots are often low or medium in volatility, meaning the wins can be smaller and more frequent, which may not appeal to those who prefer big wins.
Low RTP Slots: Pros and Cons
Lower than 90%
Low RTP slots, on the other hand, can offer the excitement of higher volatility. With RTP percentages lower than 90%, these slots can be riskier but can offer huge payouts if you’re lucky.
The trade-off is that you’re likely to experience longer dry spells, making these games better suited for players who enjoy high-risk, high-reward scenarios.
How Does the Random Number Generator (RNG) Work?
The RNG is a crucial element in slot machines, ensuring that each spin is independent and random. It is a software algorithm that constantly generates random numbers (even when you’re not spinning). Each number corresponds to a specific symbol combination on the reels.
When You Hit “Spin” the RNG picks a number at that exact millisecond, deciding your result.
The game’s animation”(spinning reels) is just for show—the result is already set.
A few facts about RNG in slots:
- Outcomes are provably random (like lottery numbers).
- No past spins or patterns affect future results—every spin is independent.
- Licensed casinos use audited RNGs (e.g., by eCOGRA) to ensure fairness.
- Slots are luck-based—RNG guarantees randomness, not wins.
The RNG guarantees that no matter how often you play, the odds are the same on each spin, making slots an entirely chance-based game.
