The four bonus buy tiers and what each one triggers
Verified Bonus Buy tiers
| 100× base bet | Instantly triggers one of the available Free Spins features |
|---|---|
| 250× base bet | Triggers a higher-tier Free Spins feature |
| 500× base bet | Triggers an upgraded Free Spins feature |
| 1,250× base bet | Triggers the highest-tier Free Spins feature |
The cost scales with the round you're buying into: the cheapest tier drops you into the standard feature, while the top tier guarantees the strongest version of it. Because the price is a multiple of your own stake, the real cash figure moves with your bet size. Set the base bet at €1 and the four buys cost roughly €100, €250, €500 and €1,250; set it at the €0.20 minimum and the same tiers cost about €20, €50, €100 and €250. At the €240 ceiling the numbers become very large, so the tier you pick and the stake you set both decide your exposure on a single purchase.

What you're buying
A Bonus Buy skips the natural trigger - which the game rates at roughly one bonus every 443 spins - but the Free Spins that follow use the same tumbling wins, Pay Anywhere payouts and multiplier symbols worth up to 2,500×. The buy removes the wait; it does not change how the round pays or guarantee it pays well. Treat each tier as the entry ticket to a high-variance round, not a shortcut to a return. The safest first move is the free demo.
Two Feature Buy prices with undefined effects
Two extra Feature Buy options are listed - one at 20× and one at 250× the base bet - but Pragmatic Play does not state what feature effect either one triggers. Because that detail isn't specified, don't assume what they do; check the exact behaviour in the game's own paytable before paying for either.

How scatters trigger the Free Spins round
The Free Spins round starts when four or more scatter symbols land anywhere on the 6×5 grid. That trigger awards 15 Free Spins to begin the feature - the same round a Bonus Buy drops you into directly.
Once you're inside the feature, scatters keep working. Landing three or more scatters during Free Spins retriggers the round and adds 5 more spins on top of what's left, and this can happen more than once, so a strong session can run well past the opening fifteen. There's no fixed cap stated for how many retriggers you can chain.
Scatter trigger at a glance
| Trigger | 4+ scatters anywhere on the 6×5 grid |
|---|---|
| Initial award | 15 Free Spins |
| Retrigger | 3+ scatters during the feature add 5 spins |
| Natural rate | ≈1 bonus every 443 spins |

If you're waiting for the feature naturally, the game rates the trigger at roughly one bonus every 443 spins on average - a long-run figure, not a schedule, so gaps between features can be much shorter or much longer than that. The scatter is the single gatekeeper here: no scatters, no Free Spins, whether you're spinning normally, using the Ante Bet or buying in. That's why the buy exists at all - it guarantees the four-scatter start without the wait.
The four Free Spins modes and how multipliers stack
Before the round begins, a Bonus Wheel randomly selects which of four Free Spins modes you play. You don't choose it - the wheel decides, so the same buy or the same natural trigger can land you in a different mode each time. The four modes come from two base patterns, each with a standard and a "Super" version.

Free Spins 2, running total
Super Free Spins, 10× minimum
High ceiling, high variance
Multiplier symbols can appear on any tumble and are worth up to 2,500× each, with all multipliers from the same spin combined before being applied. Because wins tumble, a single spin can chain several cascades and pile up multipliers before the total lands, that's where the big payouts come from, and also why results swing hard. Many rounds end quietly, while the rare one that stacks high multipliers in the right mode drives the game's headline potential. You can't select the mode, so judge the feature over many rounds, not one, see the RTP and volatility breakdown.
Natural scatters vs Ante Bet vs buying the feature
There are three ways to reach the Free Spins, and they trade cost against certainty differently.
Three routes to the Free Spins
| Cost | Certainty of entry | Best for | |
|---|---|---|---|
| Wait for natural scatters | Only your base spin, cheapest | Low: ~1 bonus every 443 spins, uneven wait | Maximum play time per euro if the feature can be far off |
| Ante Bet | Raised bet each spin, paid steadily | Higher: trigger chance up 1.25×, 2.75× or 5.5× | Reaching the feature more often without one big hit |
| Bonus Buy | 100× to 1,250× base bet, one large outlay | Immediate: feature starts at once | Guaranteed entry now, accepting the highest short-term cost |
None of these is automatically the best. The natural route stretches a bankroll; Ante Bet buys frequency without a single big hit; the buy buys certainty of entry at the highest short-term cost. The feature that follows is identical in each case, so the choice is really about how you want to spend to get there and how much variance you can absorb per session. For deeper route planning, see the volatile-play strategy guide.
Who the bonus buy suits, and who should skip it
The honest answer depends on your bankroll and your appetite for swings, because this is a high-volatility slot (rated 5/5) with a top prize of 25,000× and a max-win probability of roughly 1 in 1.98 million. Buying the feature does nothing to soften that, it just brings you to the volatile part faster.
Should you buy the feature?
It can make sense if you
- Specifically want the Free Spins experience rather than long base play
- Have a bankroll that can absorb several buys ending small without stress
- Set a firm ceiling on how many buys you'll make in a session
- Want to see the modes back to back, exactly what a buy delivers
Skip it if
- Your budget is modest, at a €1 base bet the cheapest 100× buy equals a hundred base spins in one click
- You can't take a short run of flat features draining a small bankroll fast
- You expect a guaranteed return, there is none on any single purchase

A middle course is to test the buy in the free demo first, watch how often rounds land near nothing versus pay well, and only then decide whether real-money buys fit your limits. If you're comparing routes, remember the Ante Bet reaches the feature more often for less upfront risk than a full buy.
