Slots that Let You Buy the Bonus Round

What Exactly is a Bonus Buy Slot?

Most slots that have bonus games have to have the reels land on very specific/lined up symbols in order to play the bonus game. A bonus buy slot allows players to bypass the spin-to-win effort and just jump straight into the bonus game.

How does the bonus buy feature work?

You will find a button on the side of the screen that will allow you to “Buy a Pass” into the bonus game. Once you click on this button, a confirmation message will appear with a brief description of the bonus game. Click to confirm, and your bonus game will begin. 

Reaching a game’s bonus round can be hard and take a long time. This feature allows you to save the spins and the lost money on those spins and open the bonus round directly. 

How Much Does it Cost to Buy a Slot Bonus Round?

Like your winnings from a bonus round, the cost of a bonus buy is dependent on the game being played and the player’s initial wager. 

Game Provider Cost to buy bonus round ($)
Pillars of Asgard NextGen 40x or 80x
300 Shields Extreme NextGen 60x
Medusa Megaways NextGen 100x
Extra Chilli Megaways Big Time Gaming 50x
White Rabbit Megaways Big Time Gaming 100x


*Did you know?

Big Time Gaming was the first software provider to introduce the bonus buy feature to slot games with their White Rabbit slot in 2017.

Buying a bonus round - Pros and Cons

Pros Cons
  • Immediate bonus game action
  • No money wasted on spins that award no winnings
  • Increases chance for big wins
  • Expensive to buy pass
  • Not guaranteed big wins in the bonus round
  • Not available for all games in every market

Tips on How to Use the Bonus Buy Round

It’s best to use the bonus buy round only when you have the funds to be able to do so. Again, buying the pass to a bonus round is not cheap. 

Because of this, it is best to put limits on your account for these games to make sure you are not exceeding your own funding limits. For more information on responsible gambling visit our page here.
