Bonus Buy Slots

There’s always a spot for a slot in a casino game selection, and there’s more than one slot around. As you know, the slot catalogue is a pretty big chunk of the overall game selection. That’s because game producers make sure to pump out lots of titles. One of the latest special addition to online slots is bonus buy feature.

Providers try to make their game stand out in many ways. Slots come in a variety of themes, in addition to which you’ll see them coming with a number of features. For example no modern slot is complete without Wilds and Scatters.

A free spins feature is pretty common as well. With the addition of cascading reels, retriggers, nudges and holds you get an abundance of slot features. In other words, developers like their features and love experimenting with them.

That’s why you’ll find slots where you can buy the bonus feature. This kind of feature lets you cut to the chase and enjoy the bonus feature. So, what is the bonus buy feature all about?

The above list of casinos with Bonus Buy Slots is frequently updated and should be 100% accurate.

What are Bonus Buy Slots?

As you know, slots can have repetitive gameplay. Yes, the Scatters can trigger an interesting bonus feature to break the monotony. However, Scatters don’t just fall down from the sky. They land randomly so you don’t know when to expect them.

That’s where the Bonus Buy Slots come in. Unlike other slot features, the bonus buy feature doesn’t need a trigger. You can turn it on whenever you want. However, you have to pay a price. This price is usually 50 to 150 times your stake.

In other words, the buy feature slots can be costly. But you get to play the bonus round after you pay. This means that you have a fair shot at getting that money back and then some. That’s precisely the point of a bonus feature.

Should you buy the bonus feature?

One important thing to consider is your bankroll. Since the bonus buy feature slots cost a bit, you need to manage it accordingly. Depending on the slot type, you’ll be able to trigger the feature multiple times. However, should you go for the bonus buy feature this often?

One of the consequences is depleting your bankroll. In other words, you should use the bonus buy feature strategically. Yes, you get the potential for really big wins, but you also get the possibility of losing is just as big.

How does it work to buy the bonus round?

Some of the best bonus buy slots are logically the most popular ones. Typically, you’ll see the bonus buy feature on the player’s table. All you need to do to activate it is click on it. But you should check your balance beforehand.

The feature can cost 50 to 100 times your stake. So, if you don’t have a big stake you can’t trigger it. Moreover, you need a big bankroll to play these games. That goes in hand with careful management.

High Volatility means High Potential Wins

The slots where you can buy the bonus also come with high volatility, meaning you can expect big payouts over the long run. But the bonus buy feature takes a toll on your bankroll. If you go for it a few times in a row, you could burn through your money quickly. However, it could also give you a chance to get some big rewards faster. All in all, it depends on how good you manage your bankroll. Making the right decision in-game will put you on the winning path.

Raise RTP

Now that you know that some bonuses buy slots have high volatility, you need to consider another thing. That’s the RTP of the game. In these types of slots, the RTP rises during the bonus feature. This means that you can expect a bigger payout.

High RTP combined with high volatility means we can expect big payouts quite often. That’s why you have the bonus buy feature. With it, you’ll get a better shot of winning bigger prizes.
