How RTP and volatility affect payouts

Introduction

When choosing a slot, many are guided only by the bright design or popularity of the game. But experienced players know: the main factor affecting the long-term profitability and behavior of the machine is RTP (Return to Player) and volatility. These parameters determine how the winnings are distributed, how often they occur, and what their potential size is.

What RTP is and why it matters

RTP (Return to Player) is the theoretical percentage of return to players from all bets placed in a slot over a distance of millions of spins.

Example: a slot with RTP of 96% means that on average, with an AU turnover of $100,000, players will be returned AU $96,000, and the casino will retain AU $4,000 (margin).
Important: RTP works only at a distance; a single session can show both 50% and 500% return.

Practical conclusion: the higher the RTP, the smaller the statistical advantage of the casino and the more profitable the long-distance slot.

What is volatility and how it works

Volatility is the level of risk and distribution of winnings:
  • Low volatility - frequent but small payouts (example: Starburst, Big Bass Splash at low rates).
  • Average volatility - balance between size and frequency (example: Sweet Bonanza, Book of Dead).
  • High volatility - rare but large winnings (example: Wanted Dead or a Wild, Money Train 4).

Example of distribution:
  • A slot with RTP 96% and low volatility gives RTP evenly, due to constant small payments.
  • A slot with the same RTP, but high volatility, can "silence" hundreds of spins, and then issue x1000.

How RTP and volatility work together

1. High RTP + low volatility

Long game sessions without strong hesitation.
Good for players with limited bankroll and those who like to "play longer."

2. High RTP + high volatility

The best option for hunting large winnings.
Suitable for high rollers or players willing to endure losing streaks.

3. Low RTP + low volatility

Suitable for beginners to "warm up," but long-term unprofitable.
Payouts are predictable, but on average far inferior to slots with RTP above 96%.

4. Low RTP + high volatility

The riskiest option: long drawdowns and less mathematical expectation.
It makes sense only for the sake of unique gameplay or jackpot mechanics.

Examples of calculations in practice

Suppose we have two slots with RTP of 96% but different volatility:
  • Slot A (low volatility): Average x2 gain every 5-10 spins.
  • Slot B (high volatility): winning x200-x500 times in 300-500 spins.

Players with an AU $100 deposit:
  • In slot A, they will be able to play for 1-2 hours and will receive frequent returns, but the chance of a large win is minimal.
  • In slot B, a bankroll can end in 15 minutes without a bonus, but with luck, it is possible to multiply the deposit tenfold.

What experienced players pay attention to

RTP ≥ 96% is the minimum benchmark for long-term play.
Volatility under strategy:
  • For a short session, the → is low/medium.
  • For hunting for large payments, the → is high.
  • Combining parameters with bankroll:
    • Small deposit → low volatility, otherwise rapid zeroing.
    • Medium and large deposits can → go into high volatility.

    Typical player mistakes

    1. Ignoring RTP. Many people think that the slot "pays a lot" if someone has shown a skid, but the statistics only work at a distance.
    2. Wrong choice of volatility. Beginners often go into high dispersion without a sufficient bankroll and lose too quickly.
    3. The rate is higher than the budget. In highly volatile slots, this leads to a rapid loss of deposit.
    4. Misunderstanding Buy Feature. In slots with a purchase bonus, payments are often concentrated in it, and a regular game gives little.

    How to use RTP and volatility in your selection

    For long-distance play: Opt for high RTP and medium volatility.
    To hunt for a big win: high RTP and high volatility, but with a bankroll margin.
    For bonus hunting: slots with high volatility and Buy Feature, where drifts happen in bonuses.
    For beginners: low or medium volatility to understand mechanics and not lose a deposit quickly.

    Conclusions

    RTP determines the mathematical expectation of a win, and volatility determines the nature of its distribution.
    Two slots with the same RTP can behave completely differently: one will give many small wins, the other - rare, but large.
    Experienced players always match RTP, volatility and their bankroll to choose the optimal strategy.
    There is no universal "best" combination: it all depends on the player's goals - to play longer or catch one big win.
