How Is RTP In Slots Calculated?
In order to determine the RTP of a specific slot game, there are a few variables to consider. These variables include the total number of wagers, as well as the total amount won by players.
RTP is calculated with a pretty simple formula. The formula is as follows:
Slot Machine RTP = Total number of wagers / Total Player Winnings
Here are a few practical examples:
| Total Wagers (£) | Total Winnings (£) | RTP (%) |
|---|---|---|
| 1,150,000 | 1,346,000 | 85,43 |
| 1,085,000 | 1,200,000 | 90,42 |
| 2,200,500 | 2,500,000 | 88,02 |
How Does Slot Machine RTP Compare to Other Casino Games?
Mobile slot games typically have a wide RTP range, which comes in at around 92%-98%. High volatility slot titles typically have a wider range of returns, where you’ll tend to experience greater swings in balance.
While it is true that slots appear to have a smaller RTP than some of the listed games below, its accessibility and generally low volatility allow for fool-proof gameplay and endless action.
This is how mobile slots compares to some of the most popular UK mobile casino games:
| Casino Game | RTP (%) |
|---|---|
| Slots | 97 |
| Blackjack | 99 |
| Euro Roulette | 97,3 |
| American Roulette | 94,7 |
| Baccarat | 98,9 |
| Craps | 98,6 |
| Video Poker | 99 |
| Bingo | 70-90 |
| Keno | 70-90 |
Factors affecting RTP
The RTP of your favourite slot titles is constantly shaped by you and fellow gamers alike. These are the factors that raise and lower the RTP of all major slot games.
Player skill and decisions
When employing certain strategies, games like video poker and blackjack tend to have much greater RTP scores.
Casino policies
Specific versions of games can drastically alter the RTP. On the other hand, casinos have some leverage when it comes to bumping or lowering the RTP of selected titles.
Game rules and structure
The set rules of a title may have a major impact on the RTP and volatility of a game. Two great examples of this could be the number of decks used in a game of blackjack, or the number of 0’s on the roulette wheel.
Psychological factors
At the end of the day, your approach to a game can influence the overarching RTP of a selected title. This is why strategy and a calculated approach to each title is crucial for long-term enjoyment.
RTP and Variance: Why it's Important to Understand the Difference
Variance and RTP; these terms are constantly used interchangeably by thousands of players. However, these concepts differ from one another, and it’s crucial to know the characteristics of each one.
Variance and volatility: risk and reward
Variance is the measurement of risk posed by a specific title. This rating is a reflection of the frequency and the size of your payouts. A high-variance game means you’ll expect fewer payouts, but the sum of each payout will be above average. On the flip side, low-variance games tend to have a higher frequency of smaller payouts.
RTP: an accurate projection of returns
While variance is focussed on the risk-reward metrics of a title, the RTP is used to gauge the number of earnings you can expect over a period of time. This score is determined over hundreds of rounds, as players continue to wager and cash out on a specific title.
RTP vs. House Edge: What’s The Difference?
RTP will always tie in the with the advantage held by your mobile casino of choice. Many players fail to remember that their biggest competitor will always be the house. So, how exactly does the house edge differ from RTP?
House Edge: An unseen advantage
The house edge is a mathematical advantage held by the game, which differs from one casino to the next. This score will always lean in favour of the casino’s success, which means this can negatively impact you as the player.
However, most mobile casinos tend to keep this fair, allowing an open playing field that’s focussed on back and forth action. A casino needs to make money in order to keep things running, so you’ll always find yourself playing around the house edge.
Calculating the House Edge
The house edge is simply the RTP of a game deducted by 100. So, if a game holds an RTP of 98%, the house edge will be set at 2%.
Formula: 100% – RTP%
House edge versus RTP
| Aspect | House Edge | RTP |
|---|---|---|
| Definition | The percentage of all bets that the casino expects to keep as profit over time. | The percentage of all wagered money that a game is expected to return to players over time. |
| Perspective | Focuses on the casino’s perspective, emphasizing the profit the casino expects to make from each game. | Focuses on the player's perspective, indicating what players can expect to get back from their total bets. |
| Implication | A higher House Edge means higher costs for the player over time, as the casino retains more of the wagered money. | A higher RTP indicates a better potential return to the player, implying they will lose less over time. |
| Impact on Gameplay | Affects casino decisions on game promotion and rule settings to ensure profitability. | Used by players to choose games that theoretically offer better payback, impacting their betting decisions. |
| Strategy | Strategy Casinos use House Edge to determine which games are most profitable and may adjust rules to increase it. | Players use RTP to select games, helping them manage their bankroll by picking games with better long-term potential returns. |
