Bonus buy slots are online casino games with a feature that allows players to pay a fixed price for immediate entry to a bonus round. Rather than spinning the base game and waiting for scatter symbols or another natural trigger, a player can select a purchase option and access the feature straight away.
This mechanic is also called a feature buy, bonus purchase, or feature drop. It is designed for players who want direct access to a slot’s most eventful features, such as free spins, win multipliers, cascading wins, expanding wilds, prize wheels, or jackpot opportunities.
While the appeal is easy to understand, bonus buys require careful budgeting. The price is commonly expressed as a multiple of the current stake, and a typical purchase may cost around 100 times the selected bet. That means a game played at a £1 stake could require a £100 payment to buy the bonus feature. Some games offer lower-cost and higher-cost bonus options, each with different possible outcomes.
How a Bonus Buy Slot Works
In a conventional online slot, a bonus round is usually triggered when enough scatter symbols land on the reels. The trigger is random, so there is no guarantee about when it will happen. A bonus buy changes this route: the player pays the displayed amount and enters a bonus sequence immediately.
The purchase price normally changes with the selected stake. If a bonus costs 100x the bet, the price scales up or down in line with the wager size.
| Selected stake | Example bonus price | What the price means |
|---|---|---|
| £0.20 | £20 at 100x | One immediate bonus-round entry |
| £0.50 | £50 at 100x | One immediate bonus-round entry |
| £1.00 | £100 at 100x | One immediate bonus-round entry |
| £2.00 | £200 at 100x | One immediate bonus-round entry |
The amount paid buys access to the feature, not a guaranteed win or a particular payout. A bonus round can produce a small return, a significant return, or in some cases no return. As with all slot outcomes, the result is determined by the game’s random number generator and the applicable game rules.
Why Bonus Buy Features Appeal to Players
The central benefit of a bonus buy is speed. Bonus rounds often contain the mechanics that make a slot feel especially dynamic, and buying access removes the potentially long wait for a natural trigger.
Depending on the title, an instant feature purchase can offer access to:
- Free spins with enhanced symbols or altered reel sets.
- Multipliers that can increase winning combinations.
- Cascading or avalanche mechanics that create multiple chances from one feature spin.
- Expanding wilds that cover more reel positions.
- Pick-and-click games, prize wheels, and mystery awards.
- Hold-and-win features with cash prizes or jackpot tiers.
- Bonus rounds with selectable risk levels or different volatility profiles.
For players in jurisdictions where the mechanic is legal and available through a properly licensed operator, the feature offers a clear and transparent trade-off: pay a stated price for instant bonus access. That transparency can make it easier to understand the cost of the decision before confirming it.
How to Compare Bonus Buy Slot Games
For eligible players in markets where the feature is permitted, comparing more than the headline buy price can lead to better-informed choices. A low price may provide a different feature structure from a premium purchase, while a high maximum win can also come with very high volatility.
With those fundamentals in place, players can learn more about what bonus-buy mechanics offer and the level of risk they involve.
