Bonus Buy Slot Games
Bonus Buy feature lets players pay a fixed multiple of their stake to enter Free Spins or another bonus feature directly.
How Bonus Buy Features Work in Slots
Bonus Buy is a slot feature that allows players to pay an additional amount to enter a Bonus Game directly instead of waiting for it to activate naturally during the base game. The purchase price is usually calculated as a multiple of the current stake.
The feature is most commonly used to access Free Spins, although some games offer several purchase options with different rules, volatility levels or bonus modifiers. A more expensive option may provide enhanced Multipliers, additional special symbols or improved bonus conditions.
Bonus Buy does not change how the underlying slot mechanic works. Once the feature begins, the game may still use systems such as Pay Anywhere, Cluster Pays or Tumble Reels to determine wins.
The exact cost and availability of Bonus Buy vary by game and jurisdiction. Some regulated markets restrict or disable the feature entirely, so the same slot may offer direct bonus purchases in one region but not another.
Vortex: A Cheaper, Chance-Based Alternative
Vortex, introduced by Just Slots in its 2026 release Ice Vacation, reframes a standard Bonus Buy as a gamble rather than a fixed purchase. Instead of paying full price for a bonus round, players choose a wager between 10% and 90% of the standard cost and pick how many Vortex Wheels to spin, from 1 up to 3. Every wheel has to land successfully to award the selected bonus; if any wheel fails, the wager is lost and the game returns to the base round.
The lower the chosen wager, the lower the odds of every wheel succeeding, so Vortex does not lower the effective cost of a bonus round on average, it trades a guaranteed purchase for a cheaper shot at the same outcome. Just Slots has said the mechanic will roll out across future releases alongside a new VIP Shop, rather than staying unique to one game.
