Features of calculating winnings with a purchased bonus
The Buy Feature allows the player to purchase a bonus round with a fixed amount without waiting for scatters to fall out. However, this mode has features that directly affect the final calculation of the winnings. To understand the real value of a purchase, it is important to take into account the mathematics of the slot: bonus price, RTP, volatility and coefficient distribution.
How the purchase price is formed
The bonus price is usually expressed in multiples of the player's bet:
This amount is not returned directly, but is converted into a chance to launch the bonus mode. All further winnings are counted from the base bet, but taking into account the fact that the player has already "invested" the purchase price.
Payoff math on purchased bonus
1. The base rate remains the same.
If a player plays at $1 and buys a bonus for 100x, he pays $100, but all payments are calculated based on the $1 bet. If he wins $200 in the bonus, the final result is $200 - $100 = $100 net profit.
2. RTP may differ from the main game.
In some RTP slots, the bonus is higher than the base to justify the cost. For example, in Money Train 2, the RTP is higher when buying a bonus than when starting normally. But there are also reverse examples where the purchase gives a slightly underestimated value.
3. The distribution of winnings is volatile.
The bonus can give both a minimum payout (for example, 10-20x from the bet), and a multiplier of many thousands. Most winnings fit into the "middle zone," but it is rare super-winnings that form the mathematical expectation.
4. The maximum multiplier is taken into account.
Each slot has a payout ceiling: 5 000x, 10 000x, 50 000x. When the limit is reached, the round stops and the game pays the maximum winnings. This is important to consider when evaluating the real value of the bonus.
Calculation examples
Example 1: standard purchase
Bet - $2.
The cost of the bonus is 100x = $200.
Bonus winnings - 250x = $500.
Bottom line: $500- $200 = $300 net winnings.
Example 2: bad bonus
Bet - $1.
The cost of the bonus is 100x = $100.
Winnings - 20x = $20.
Bottom line: $20- $100 = minus $80.
Example 3: super win
Bet - $1.
The cost of the bonus is 100x = $100.
Winnings - 5 000x = $5 000.
Bottom line: $5,000- $100 = $4,900.
What affects the calculation of winnings
1. Bonus type.
Super Bonus almost always has above average winnings, but its price makes the outcome less predictable. Mystery may cost less, but the risk of a weak bonus reduces efficiency.
2. Round duration.
In progressive multiplier or cascade pay slots, long bonuses are almost always more lucrative.
3. Frequency of "empty" bonuses.
Most of the purchased bonuses return less than their value, and this must be understood in advance.
4. Slot specifications.
RTP, volatility and frequency of overwinds form a mathematical model. One slot can give more often, but less, the other - rarely, but tens of thousands of times more bet.
Result
The calculation of the winnings for the purchased bonus is based on a simple logic: all payments are calculated from the base rate, and the purchase price is an investment that needs to be repulsed. It is important for the player to take into account the RTP bonus, the maximum multiplier and risk distribution. Buying can bring both a loss and record winnings, so this mechanics requires a clear understanding of mathematics and readiness for high volatility.
How the purchase price is formed
The bonus price is usually expressed in multiples of the player's bet:
- standard cost - 100x of the rate;
- extended versions (Super Bonus) can cost 150x-200x;
- Mystery- or Random-options - from 80x to 120x, depending on the potential outcome.
This amount is not returned directly, but is converted into a chance to launch the bonus mode. All further winnings are counted from the base bet, but taking into account the fact that the player has already "invested" the purchase price.
