Fixed and variable bonus price slots

Introduction

The Buy Bonus feature has become one of the most popular in modern online slots. It allows players to instantly activate the bonus round without waiting for Scatter characters to appear. However, a key factor in this mechanic is the purchase cost, which can be fixed or variable. These two approaches strongly influence strategy, risks and perceptions of the game.

Fixed bonus price

In fixed-cost slots, the player always pays the same amount to activate the bonus round.

Main features:

• The price is expressed as a multiplier of the bet (usually 50x, 75x or 100x).
• The cost is independent of the current state of the reels or past spins.
• The player knows in advance how much he will pay for the freespins.
• Risk and potential return are balanced and predictable.

Examples of slots:

• Sweet Bonanza (Pragmatic Play) - fixed price 100x bet for the purchase of freespins.
• The Dog House Megaways (Pragmatic Play) - the cost is fixed and tied to the bet.

Advantages:

• Full transparency and predictability.
• Handy for players who love stability.
• It's easy to calculate a bankroll strategy.

Disadvantages:

• Lack of flexibility.
• Sometimes seems too expensive for small bets.

Variable bonus price

In variable cost slots, the purchase price may vary depending on the parameters of the game.

The main factors affecting the price:

• 1. Bet size - the higher the bet, the more expensive the bonus.
• 2. Selection of modifiers - the player can activate additional conditions (more rows, superbonus, increased multipliers), which increases the price.
• 3. Complexity of mechanics - some slots offer different types of bonuses, each with its own price.

Examples of slots:

• Book of Shadows (Nolimit City) - the price depends on the number of rows (3, 4 or 5).
• San Quentin (Nolimit City) - several purchase options: from a minimum bonus to a "super bonus" at an increased cost.
• Hacksaw Gaming slots - Often offer multiple variable price Buy Features.

Advantages:

• Flexibility and choice of risk level.
• The player can adapt the strategy to his bankroll.
• Increased sense of control over the game.

Disadvantages:

• It is more difficult to predict the result.
• The high price for "premium" bonuses can quickly eat up bankroll.

Conclusion

Fixed-price bonus slots are suitable for players who prefer simplicity and predictability. They allow you to calculate the strategy in advance and avoid unexpected expenses. At the same time, variable price slots offer more control and customization of the game, but require more experience and readiness for high risks.

Both approaches are in demand in the market: the fixed model is more liked by beginners and players with a limited budget, and the variable is liked by high rollers and those who are looking for flexibility and variety in the gameplay.
