What Are Bonus Buy Slots?

Bonus Buy Slots are real money video slot games that give you the option to buy your way directly into the slot game bonus round. It's a unique feature that allows players to take control of their gaming experience.

Why would you want to play the bonus rounds directly and skip the base game entirely? Well, in some games, the bonus rounds offer better chances to win bigger prizes than in the base game, so naturally, they are more ‘interesting’ for the player.

Now, it is important to point out that the games that offer this functionality, which are sometimes also known as ‘Buy Feature slots’, are not always available in all countries. Some jurisdictions, such as the UK, prohibit slots where you can buy the bonus. They do so as a deterrent for problem gambling. If Bonus Buy Slots are available where you live, be aware of the costs involved in using this option and do not spend more than you can afford.

The Bonus Buy Mechanic Explained

There’s nothing complex about real money online slots where you can buy bonus features. Instead of waiting for the right combination of symbols to land on the reels and trigger a bonus round naturally, you have the option to pay a fee to access it instantly. The cost is not fixed, but depends on the bet amount you’re playing with. It typically ranges from 50 to 200 times your bet. This varies from one slot game to another.

Once you set your bet amount, you will see the price of the Bonus Buy feature on the screen. When you commit to buy it, the cost will be deducted from your casino account balance.

Casinos.com Trivia

White Rabbit was the first game ever to introduce the Bonus Buy concept. It was created by Big Time Gaming in 2017.

Why VIP Players Prefer Bonus Buy Slots at VIP Casinos

VIP players often gravitate toward Bonus Buy slots in VIP casinos.  The reason is these games align with their high-stakes gaming preferences. Unlike standard slot games, Bonus Buy slots allow players to bypass the base game and directly purchase entry into the lucrative bonus rounds. VIP players typically value efficiency and the thrill of big wins. Which is why this feature is so attractive. It eliminates waiting periods and enhances the gaming experience by fast-tracking access to the most exciting aspects of the game.

Additionally, Bonus Buy slots often come with higher volatility. The potential payouts during the bonus rounds is greater. Both these items perfectly complement the risk appetite of high rollers. VIP players are accustomed to playing at elevated stakes. They appreciate the opportunity to invest in features that provide a heightened sense of control and customization. By choosing Bonus Buy options, they can adjust their gameplay to suit their preferred level of risk and reward. Bonus Buy slots create a tailored gaming experience that reflects their elite status.

Finally, VIP casinos often curate a selection of premium Bonus Buy slot titles. The best slots in this category come with cutting-edge graphics, innovative gameplay mechanics, and exclusive features. These factors ensure their high-end clientele receive the best entertainment possible. This curated selection not only meets the expectations of discerning VIP players but also adds to the exclusivity of the casino’s offerings.

How to Win on Bonus Buy Slots

Any slot that features the bonus buy option is powered by a Random Number Generator engine (RNG for short). This technology ensures fairness since the outcome of a spin is always generated at random and cannot be tampered with (to learn more, you can check our Complete Guide to Video Slots). 

This also means that there is no strategy you can use to generate the wins you want. You can only hit the spin button and hope for the best. Which is actually what makes playing online slot games fun! To make the most of your Bonus Buy experience:

  1. Choose Your Game: I have made a list of the games I think are top in the buy bonus category. But these are only suggestions since I know that different people have different tastes in games!
  2. Try Free Play Mode: Is the game available in demo mode? If yes, you can use the dummy funds to buy the bonus in free play mode and get a feel of the game before committing any real-money bets.
  3. Buy Bonus and Play: If you’re ready, make sure you have enough funds to cover the cost of purchasing the bonus and go for it!

Trying Bonus Buy Slots in Free Play Mode

In some countries, you can get access to a demo version of a bonus buy slot you would like to try. The demo, or ‘free play mode’ is great to test the waters and discover what to expect once you unlock the bonus rounds of the game.

When you feel ready, you can switch to real money play and buy the bonus for real.

While in free play mode, you will not be committing any of your own money. Instead, you will use a virtual balance to buy your way into the bonus features. Naturally, any winnings you land while playing slots for free cannot be withdrawn as real cash.

Ready to Try Bonus Buy Slots?

The Bonus Buy Slots mechanic gives you direct access to the most exciting part of the game, the bonus features. To do this, you need to commit a chunk of your casino funds up front, usually calculated on the bet amount you select. Fun is a guaranteed element in slots where you can buy bonus, and there are many different games to choose from. What’s more, the popularity of these games makes them available on all the best rated online casinos (given that the feature is enabled in your area).  

Despite the benefits, you should always use this feature with care, since you could be risking a considerable amount of money and there’s no guaranteed return.

Where to Play Bonus Buy Slots

The one thing you should not be worried about is finding a place to play the best bonus buy slots. These games are so popular that you can find them practically at any online casino worth its salt. Here’s a list of the most reputable sites:
