But what are Bonus Buy slots? How are they different? And why should you play them and buy their extra features? Let's find out!

What are Bonus Buy Slots?

Bonus Buys are slots where you can buy a bonus. Apart from that, they feel like regular machines, and you are not obliged to buy the bonus - it’s optional. Players can trigger these bonus functions naturally by winning in the standard mode. However, that might take considerably more time and money than a player could have invested to buy the feature.

The hype behind Buy Bonus Feature slots comes from the extreme benefits they bring a player. Bonus Buys are basically extensions of the player's favorite machines and winning potential. So, the role of Buy Bonus features is to shortcut the gambler to this terrific part of the game.

There are many types of Bonus Buys and reasons for gamblers to buy them. Read on to explore the issue.

How Bonus Buy Slots Work?

Want a Bonus Buy? It’ll take a few seconds to buy it. Whenever luck shines down on you, open the online slot machine with the Bonus Buys you like, choose the one you prefer, set up the bet sum, and pay the price. You've read that right! Many Bonus Buy features allow players to select among multiple splendid extras to which they want to be exposed. Gamblers can sometimes pick between multiple Bonus Buy types inside a game.

Types of Bonus Buys

As we said, some slot machines allow players to choose among multiple Bonus Buys. That's a solution developers approached to cover a more prominent player audience in their games.

Free Spins

This Buy Bonus feature allows players to buy a package of spins with exceptional advantages like larger bet multipliers, more special symbols, sticky Wilds, and other perks they won't come across in the regular mode. The price of this Bonus Buy relies on the slot's fixed multiplier and the gambler's total bet. Depending on the potential payout of such Buy Free Spin slots, developers might assign different price multipliers to the Bonus Buys in their machines. Free spins packages might vary in size, too. You will most commonly encounter sets of 10 free spins in slot machines.

Gamble Rounds

These mini-games involve card guessing, Heads and Tails, Wheel of Fortune, and other instant wins. Before you activate the round, you might need to choose whether you want to collect your winnings gained in the regular mode and leave or risk them for a chance to double, triple, or quadruple them. The higher risks you take in the gamble round (guess the suit of a card, for instance), the more extensive benefits you will earn. However, if you guess poorly, you will lose your prize. So, it's your choice whether to accept the dare each time. Gamble rounds supplement the slot's free Bonus Buy spins game - players may take a risk and, if lucky, increase their FS or use up the ones they buy immediately.

Bonus Games with Individual Plots

Such slots with a Buy Feature are rare instances when software manufacturers want to explore their creativity and develop new solutions to traditional online gambling. They supplement their online machines with irregular Bonus Buys with their own gameplay and rules. These Bonus Buys sometimes test players' skills, like reaction and strategic decision-making. So unprepared players will likely be at a substantial disadvantage since they might lose simply because of not knowing the rules.

Whichever buy feature you come across is beneficial in some way. It boosts the game's initial RTP and increases your chances of winning.

Special Symbols

Once you buy the bonus feature, the online slot will generate the required symbol combo that typically triggers it. Then, the game will provide you with some options of free spins packages, mini-games, or other Bonus Buy variations, if any. You might even come across a gamble round before you start on your bonus. Follow wherever the slot takes you, trust your intuition and luck to make the right decisions, and jump into the restless fun!

Most of the slot's unique features will unlock during the Bonus Buy play. Let's explore the special symbols you will encounter.


These are the most common special symbols in a Bonus Buy slot. They can substitute for regular icons to complete paylines and win you more cash. Wilds can become sticky, gain a multiplier, expand, stack, and perform other actions in bonus rounds to increase the player's winning potential.

Bonuses & Scatters

Such symbols are similar in functionality, so slots usually feature one or the other. You unlock bonus features built into the title if you get several Bonus symbols or Scatters (usually 3 or more). If the game has both Bonuses and Scatters, these symbols will trigger alternative extra features - free spins, gamble rounds, etc. The functionality assigned to these symbols depends on the provider's imagination. Read the Terms and Conditions individually for each game to determine the roles of symbols. During the bonus play, Scatter and Bonus symbols often expand functionality like Wilds - stick, stack, expand, multiply, etc.

Colossal Symbols

These are icons that initially occupy several cells on the reels, giving the player the potential to trigger multiple paylines and win more cash. Bonus Buy slots might employ such symbols in the extra round and sometimes in the regular play mode.

Cascading Reels

This is a fascinating feature in bonus games of slots. Here is how it works. The symbols keep falling, forming paylines, and disappear after cashing out when other dropping icons replace them. The symbols keep cascading within a single spin until no more winning combinations are formed. Cascading reels allow a gambler to hit multiple wins within a single bonus spin, for example.

Software providers regularly develop brand-new, alluring offers to satisfy their players. So, we have touched only the tip of the iceberg with these commonly included symbols and features. You will encounter so much more as you play Bonus Buy slots and buy bonus games on
