What Are Bonus Buy Slots?
Bonus buy game slots are casino games that allow you to pay a fee to jump straight to the bonus rounds. With traditional slot machines, bonus premium features are triggered randomly. But, this is where the fun and high winning potential lies.
Game providers release bonus buy slot games to give players a chance to upgrade their gameplay. These games are intended for players who are willing to place a higher stake for a chance at increasing their winning potential. With that being said, it’s essential to remember that slots with bonus rounds are still a gamble, and there is no guarantee of winning.
The main benefit of these slots is that players don’t have to wait and see when it comes to bonus frequency. They can activate the features immediately and enjoy the thrills.

Rules & Conditions for Bonus Buy Slots
Before exploring the world of buy bonus feature slots UK, it’s important that you understand the terms and conditions. If you don’t know the rules, you may not get to enjoy the full experience.
Cost of Bonus Buy
The slots features of bonus buy games give players an edge to potentially win more money. In order to activate this, there is an additional cost. This is placed on top of the wager you set for the base game. Before playing bonus buy online slots, it’s essential to work the additional cost into your budget.
RTP & Volatility
Activating the bonus buy feature will change the RTP and volatility of a game. This is because you’re skipping the base game and heading straight into the high-risk for high-reward round. You may notice a slight increase in the game’s RTP rate when this mode is activated.
Eligible Games
While the bonus buy feature is a fan-favourite, it’s not available with every slot game. Luckily, many casino sites have a section dedicated to these games. Always check a slot game’s details for more information on this feature.
Max Win Potential
With many slot games, players cannot access the max win amount in the base game. The bonus buy features allow players to take their shot at hitting those maximum multipliers. Basically, you get a direct shot at the highest possible prize in a game.
Demo vs Real Money
The Slotozilla team highly recommends testing out a free slot machine without downloading with the bonus buy feature before wagering real money. Playing demo games can give you insight into what the experience is like, basically letting you know if it’s worth spending the extra money on compared to base games.
Wagering on Bonus Buy Promotions
If you’re playing with a bonus or promotion from the casino, it’s important to review the terms and conditions for eligible games. Some casinos prohibit players from using bonus money on feature buy slots. If you are allowed to play, the wagering contributions may not be as high as traditional slots.

Responsible Gambling with Bonus Buy Slots
Since bonus buy titles could eat up your budget quicker, it’s important to approach these games with a responsible mindset. The higher cost per spin does put players at a higher risk when it comes to losses. Luckily, the best online casinos in the UK take responsible gambling seriously. They provide tools that allow you to set account limits and request cool-off periods. These sites also provide links and resources to reputable organisations, like GamCare and BeGambleAware, for further education.
Alternatives to Bonus Buy Features
Unable to find bonus buy online slots at your favourite casino platform? Don’t worry! There are plenty of exciting alternatives to try out.
Free Spins Slots
Many casinos provide a free spins bonus for slot games. You will receive a set number of spins that you can play on a promoted game for a chance at winning real money. Each free spin has a determined value that cannot be altered.
Ante-bet / Feature Bet Slots
The ante-bet is similar to bonus buys. Unlike the feature buy slots that automatically activate the bonus round, the feature bet slots allow players to pay a premium for an ante-bet that boosts their chances of activating extra features, like specialty wilds, higher multipliers, and other additions.
Promotions / Bonus Rounds via Gameplay
Another fun way to increase your winning potential is to use promotions, like free spins or bonus funds. This allows you to enjoy slots with a chance at activating the bonus rounds without having to pay extra to extend your gameplay experience. Basically, you get more chances to win for your dollar.
