Slots Where You Can Buy Bonus: What Are They?

Suppose you are playing a classic video slot: Let’s say you are playing the Pharaoh’s Fortune slot machine or you decided to try your luck on the Valkyrie slot machine. All of these games have a bonus feature that you can activate when you meet certain conditions. For example, when you find three scatter symbols in the Lucky Charm slots, you activate the free spin round. However, doing so depends on luck and may require you to do a lot of spins. If you are not lucky enough, you might not be able to trigger a bonus round even after you’ve done hundreds of spins.

In games like Roller Coaster slots and Center Court slots, there is a reason you want to start the bonus round: You win more often and more than ever on these rounds. So when the feature starts, you can be sure that you will make a profit. Of course, it is not possible to know the amount of this win, but this is what makes bonus rounds in slot games attractive.

Bonus buy slots are exactly the same as classic video slots in this respect. There is no difference in terms of rules and features. These games also have bonus features and you can activate them as usual. However, if you don’t want to wait, there is an option you can use: buy it. In bonus buy slots, you can trigger the bonus feature whenever you want by paying for it. Imagine playing 3 slots Captain America: If you have enough money, you can try your luck only in the bonus round instead of wasting time with the regular game. The amount you have to pay is calculated according to the bet amount and is different for each slot.

How Bonus Buy Slots Work?

Slots where you can buy bonus are still video slots, so you don’t need to “re-learn” how to play them. In fact, you can try them for free, just like regular slots: bonus buy slots free play option is available. As explained above, the only difference is the option to purchase the bonus feature. And this is very easy to do: You will see a big button on the interface that says “buy” (or “purchase). When you click this button, a menu will appear where you can specify the buy amount. In other words, bonus buy slots do not have fixed prices: You can specify this amount freely by changing the bet value. As soon as you approve the purchase, the bonus round will start.

We cannot tell what the bonus round will be: It depends on the game. Most of the time, you will activate the free spin round – the majority of 20 line slots offer this feature. And this feature is different in every game: Sometimes you get 10 spins with multipliers, sometimes 15 spins with sticky wilds, sometimes just 50 free spins. Check the paytable of bonus buy slots before purchasing the feature: This way, you can understand what you are buying.

High Volatility For Bigger Payouts


There are a couple of things you need to be aware of in order to maximize your return from bonus buy slots. First, the answer to the “do high limits slot pay better” question is no, the payout frequency does not depend on the bet values. In other words, you don’t need to spend a fortune: Even penny slots can pay quite satisfying amounts on a regular basis. The thing you need to look for is volatility. As a general rule, the higher the volatility, the bigger the payments will be. They will also happen less often but when you win, the amount will be worth all your troubles. So prefer bonus buy slots with high volatility. You can also think about playing slots where you can buy a bonus in a slots tournament: This way, you also get a chance to win a big prize.

Should You Play Bonus Buy Slots?

This depends on your budget and expectations. When you buy the bonus feature, the online casino software still offers the same RTP values, so there is no “guarantee” that you will win. In other words, you may not win a single penny even after purchasing the feature: Whether you will win or not still depends on how lucky you are. However, in general, we can say that you will be able to make a profit in the long run, especially if you prefer bonus buy slots with high volatility. Whether this profit will be enough for you or not depends on your personal expectations. We recommend checking the bonus buy slots list and try all the games on that list for free first. This way, you will have a better idea of whether it will be worth it or not.

Bonus Buy Slots Banned In The United Kingdom


At the end of 2019, The United Kingdom Gambling Commission has banned all kinds of bonus buy slots at online casinos licensed by the UKGC. As a justification, it was stated that “players spend 3 times more money than they normally do in these games.” In other words, bonus buy slots were claimed to be against responsible gaming practices. As a result of this decision, bonus buy slots UK have been removed from UK-licensed online casinos. It is still possible to play these games, but there is no buy option, you can only play them like a normal video slot. So, for example, you can still play Immortal Romance slot (and other Microgaming slots) but you can no longer purchase the bonus feature.
