What are Bonus Buy Slots

Buy Bonus slot Games

All modern slot machines have one thing in common: they offer numerous bonus features that can potentially lead to the game’s maximum win.

To activate these features, you need to land a specific number of scatter or bonus symbols, which can sometimes feel like a nearly impossible mission.

Thanks to the Bonus Buy feature (introduced by Big Time Gaming), it has become possible to skip the wait and enter the action instantly.

Bonus buy slots have the added feature of purchasing the bonus round for a determined multiplier, which can be 50x, 100x your bet, or other. Another significant advantage of buying a bonus round is the slightly higher RTP.

Types of Bonus Buy Offers Available

If you’re interested in playing slot machines with the buy-bonus feature, you’ll find several types to choose from:

1. Standard Bonus Buy Feature

This is one of the most commonly used bonus buy options in slot machines. You can directly access the free spins feature with just one added multiplier value.

Additionally, they are SSL-encrypted and have been tested by external agencies like iTechLabs to guarantee fairness.

2. Buy Different Feature

This bonus buy option lets you choose among different features incorporated in the game.

For instance, at 3 Powers of Zeus, you can buy Wild Power, Jackpot Power or Rolling Power for 35x, buy two features for 80x and buy three features, making a Power Combo for 110x.

3. Gamble Feature Within the Bonus Round

Certain games incorporate a gamble feature within their bonus rounds, providing additional opportunities to win and adding an extra element of excitement to the bonus experience.

In the event of a win, additional free spins are awarded, and a higher multiplier may occasionally be awarded.

However, in the event of a loss, you are typically either returned to the main game or your bonus may be downgraded.

4. Different Bonus Buy Multipliers

Some slot machines may present various options for bonus buys, each with different prices to choose from.

Typically, the more expensive options tend to offer higher returns, although it’s important to remember that success is never guaranteed.

How We Ranked the Best Buy-Bonus Slot Sites

We’ve considered many factors when ranking the best bonus buy slot sites.

Below, we explain these factors and how we used them to find the best casinos to play bonus buy slots.

1. Number and Quality of Games

While the number of bonus buy slots is an important criterion when choosing the best bonus buy slot sites, the quality of the games always prevails.

In this in-depth evaluation, we ensure you have vast options for bonus buy slots, apart from buying one feature for the cost of one multiplier.

Here, you can find bonus buy games that offer options for purchasing various game features, including two features at once or a combination of three features.

Additionally, we ensure to include games with lower bonus buy multipliers starting from 5x, as well as games with bonus buy multipliers catering to high rollers, going up to 800x the bet.

2. Games’ RTP

The most critical factor when selecting bonus buy slots is the return to player (RTP) percentage.

This indicates how much of the wagered amount will be returned to the player over time.

When choosing the best bonus buy slots for this guide, we paid utmost attention to ensuring that the games have a higher RTP than the industry average.

Additionally, we selected games that offer an increased RTP when you use the bonus buy option.

3. Licence and Overall User Experience

We have only selected licensed and trusted online casinos with higher player ratings without issues with deposits, payouts, or other fraudulent actions.

All the casinos in our list are licensed and have implemented the latest SSL encryption to protect your data and online transactions.

They offer games from trusted developers who have certified their games with independent bodies such as eCOGRA and iTech Labs.

We also prioritise the overall user experience and ensure that the games are available on all devices you might use.

4. Welcome Bonuses and Other Promotions

The first thing that attracts players to online casinos is welcome bonus offers for newcomers, and promotions and loyalty programmes for returning players.

All casinos on our list have generous welcome offers and promotions that elevate your gaming experience and increase your bankroll.

We pay attention to the bonuses’ terms and conditions and wagering requirements, and we can confidently say they tick all the boxes of fair play.

5. Payment Options
