Top 5 Bonus Buy Slot Machines

If you are a regular visitor to the gambling sites like Vulkan casino, you will notice that some of them have a separate section for “Buy Feature” games with quite a sizable number of titles. It pertains to the relatively new slot machine feature of bonus buying that allows players to purchase bonuses derived from free spins or other special features. And as big online casinos like Vulkan Vegas recognise the popularity of these slots, this article lists the seven best video slots that have beautifully used the bonus buying option.

What Is the “Buy” Feature in Slot Machines, and How Does It Work?

The brand-new betting option called “bonus buy” or “feature buys” has become accessible in online slots and has gained humongous popularity. It enables players to purchase bonus features instantly instead of waiting for them, which speeds up the gaming process.

Big Time Gaming (BTG) is credited with coming up with the idea. The game developer launched the White Rabbit video slot in 2017, which is regarded as the first slot machine with the Bonus Buy feature.

The system is rather straightforward: you have a button to select your bets and another button to trigger bonuses at a set price. While the costs and regulations vary for buying the features, in general, you can buy them at 50x to 100x your wager amount. All payouts are calculated depending on the triggering stake after selecting this option.

1. Dead or Alive 2 Feature Buy

Dead or Alive 2 was released in 2019 to mark the tenth anniversary of the wild west-themed cult classic, Dead or Alive, the original.

And as of May 2020, NetEnt updated it with the “feature buy” option, elevating it to a new level of brilliance. The epic sequel is among the most played NetEnt slots since its release.

With the Dead or Alive 2 Feature Buy, players can buy three scatters in the regular game and instantly start the free spins without waiting.

Buying Bonuses Does Not Mean Buying Luck: the Casino Odds Will Be the Same, While the Game Progress Will Speed Up

If not for the bonuses and occasional special features and events, slot gaming can get quite boring to keep waiting for a lucky call on a winning streak and seeing the same old reels spinning. It is reasonable that gamblers cannot control the winning potential, but that doesn’t have to mean that they cannot control the bonuses!  Hence, we have the bonus buy option that is legitimate and fun!

While general casino odds of between 50:1 to 200:1 for slot machines trigger bonuses at intervals of 5 to 20 minutes, the Bonus Buy feature allows players to cut to the chase and pay their stakes and game on straight to the wins they deserve.

Remember, this feature is not a means to improve your chance of winning. Your stake is buying you time to trigger bonuses, it is not buying you deliberate wins, and it is no greater than the game’s volatility.
