Bonus Buy Slot Features to Watch this Year
As online slots continue to evolve, one of the most popular slot features is the bonus buy. Bonus buys allow players to pay a fixed price, usually 50x to 100x their bet amount, to instantly trigger a slot’s bonus round. This gives MrZ Casino NZ players guaranteed access to potentially lucrative features like free spins, multiplier trails, locked wilds and more.
In 2025, slot providers are cooking up fresh takes on bonus buys that offer even bigger payout potential. From slots with multiple bonus buy options to choose from to buys that remain locked until certain conditions are met, these innovations aim to add an extra shot of excitement.
Escalating Multiplier Trails
One burgeoning bonus buy trend is escalating multiplier trails that grow with each successive win. Games like Iron Bank Mighty Reels take this concept to the next level by offering a bonus buy that instantly triggers the multiplier trail.
On the base game, the slot’s multiplier starts at 1x and increases by 1x with each consecutive win, up to a maximum of 10x. When you trigger the Mighty Reels Bonus Buy, however, the starting multiplier jumps to 5x and climbs by 2x per win, reaching a peak of 50x.
This exponential escalation creates the potential for some true handpay jackpots. Expect more slots to follow Iron Bank’s example in 2025 by cranking up bonus buy multiplier trails to dizzying heights.
Cascading Wins and Multipliers
Another innovation expected in 2025 is combining cascading wins with escalating multipliers. Games like Gates of Olympus released in 2022 paved the way with this formula. Its bonus buy instantly triggers the slot’s cascading wins feature, where symbols explode after each win to make way for new symbols that can create more wins.
With each cascade, a multiplier ladder increases by 1 level, starting at 1x and capped at 10x. Future slots will likely up the ante by pushing multipliers into the hundreds or more. The cumulative effect of cascades and steeply rising multipliers can lead to some legendary bonus buy payouts.
Locked Bonus Buy Features
In 2025, expect more slots to introduce bonus buys with locked features that remain inactive until certain in-game conditions are fulfilled. Relic Hunters and the Book of Faith offers an early example of this concept.
The slot contains a bonus buy that instantly activates a free spins round. But an additional feature called Locked Sticky Wilds stays locked at the outset. Each time a special Books scatter symbol lands during the round, it fills a meter. When the meter reaches 100%, the Locked Sticky Wilds unlock for the remainder of the spins.
This adds an extra layer of anticipation and excitement to the bonus buy, since players won’t know whether the meter will fill in time to unlock the sticky wilds. As slots grow more complex, locked bonus buy features that engage players with unlock requirements will likely become more prevalent.
In-Game Achievement Bonus Buys
Another pioneer bonus buy offering we’re likely to see more of in 2025 is in-game achievement buys. Some slots contain achievements or quests that award prizes when completed. Game developers are now integrating these with bonus buys that unlock when milestones are reached.
One slot that exemplifies this trend is Wild Catch. It incorporates three in-game achievements:
- Catch 50 Fish
- Catch 100 Fish
- Catch 200 Fish
When you fully complete an achievement, a corresponding Bonus Buy becomes available for 24 hours. These buys instantly activate bonuses like free spins or the slot’s Fish Catch Bonus, which awards random cash prizes.
Achievement bonus buys add an engaging gamification element that rewards players for interacting with base game features. More slots that unlock special bonus buys when quests or objectives are completed should emerge in the coming year.
These examples only brush the surface of bonus buy innovation slot developers have up their sleeves. We can expect locked bonus buys with multiple unlock keys, 2-in-1 buys that fuse multiple bonuses, achievement buys with leaderboards for the biggest payouts and other fresh concepts.
One thing is for sure – the bonus buy craze exhibits no signs of slowing down. As slots become more advanced, bonus buys will continue serving up that instant gratification players crave with some juicy rewards.
