How is RTP calculated in slots? 

Betway slots

It involves several steps that are often performed by game developers during the design and testing stages of a slot machine. Our team has written out a detailed description of how to calculate RTP for you: 

  • Understand the basic concept. RTP is the percentage of the bet amount that a slot machine is programmed to return to players over a long period. 
  • Simulate the game. To calculate RTP, developers simulate millions of spins. These simulations are necessary because they provide a large enough data set to accurately reflect the expected return. 
  • Large Spin Simulations. Developers use algorithms to simulate all possible outcomes for a given slot machine over millions of spins. This large sample size helps ensure that the RTP calculation is accurate and reflective of long-term play. 

The direct calculation of the theoretical RTP includes the following steps: 

Total Stake 

The total stake across all simulated spins is recorded. This figure represents the combined total of all bets made during the simulation. 

Total Payout 

Next, the total payout (i.e. winnings returned to players) is calculated by adding up all wins from the simulated spins. 

Rounding and adjustments  

Use the formula: RTP = (Total Payout/Total Bet) × 100 and take the average total. 

Finally, the calculated RTP can be rounded to a certain number of decimal places (e.g. 95.12%). Developers can also make minor adjustments to meet regulatory requirements or specific game design decisions to ensure fairness and compliance. 

Publishing the RTP 

Once determined, it is published as part of the game specifications. This information is often provided to players in the paytable or help section of the game. 

Key points to remember: 

  • Long-term average. RTP is a theoretical value based on a long-term play on a particular slot. It does not guarantee that every player will see a return close to this percentage. 
  • Based on the simulation. RTP is derived from extensive simulations that cover all possible outcomes of the game. 
  • Does not include variance. RTP does not take into account the volatility of the game, which affects the distribution and frequency of payouts. 

Knowing this allows players to make more informed decisions when choosing which slots to play. The percentage represents the potential return over time, not a guarantee for individual sessions.
