Online slots have evolved massively over the past 10 years and have become the ultimate game to play for winning large amounts of cash.
The game mechanics, unlike old fruit machines, are based purely on chance and randomness, whereby no skill is involved in increasing your chances of winning.
Part of this evolution is that video slots have experienced the introduction of a brand new feature known as bonus-buy or buy feature.
This feature allows online slot players to pay a specified amount (based on their stake) to skip through the regular base-game and get straight in to the bonus round action. There are a few phrases and terms that this innovative feature is known as in the iGaming industry, depending on the software developer. These include:
– Bonus Buy
– Buy Feature
– Buy Free Spins
How Bonus Buy Works
So how does bonus buy work in theory?
As the majority of online slot payouts are based on a multiplier mechanic, the bonus buy amount is relative to the stake and will increase or decrease based on the initial bet amount.
For example, a base-game bet amount may be set to €/$2, therefore the bonus buy cost will be €/$200, whereas an initial bet of €/$10 will carry a bonus buy cost of €/$1000 – 100 times multiplication of the stake.
There are some differences and variations from creator to creator, such as tiered bonus buy features, but the general principal remains consistent.
The reason why the buy slot feature cost is relative to the bet amount is because of the multiplier mechanics that the game is built on, along with the number of free spins awarded during the bonus round.

Since the introduction of bonus buy slots, many slot developers, such as Pragmatic Play, 4theplayer and NetEnt, have embraced this innovative feature and there are now over 700 different online slots where players can buy the bonus, cutting out the risk of not landing any free spins during the session of gaming.
