🔍 How We Do Bonus Buy Slot Comparisons
To provide accurate and fair comparisons, we evaluate each slot based on a set of detailed, data-driven criteria.
🧮 Criteria & Weighting
We score every contender on six pillars:
- Bonus Buy Price vs. Potential – Is the cost justified by upside?
- RTP on Purchase – Does paying the fee actually improve returns?
- Volatility Curve – How aggressive are the swings?
- Hit Frequency – Odds of at least a break‑even result.
- Entertainment Value – Visual style, audio, pacing.
- Responsible‑Play Clarity – Limits, demo, transparent rules.
Weighting favours maths (60 %) over aesthetics (40 %), ensuring the bonus buy slot comparisons remain objective.
📈 Data Collection Method
Our team runs 5 000 demo buys and 500 real‑money buys per title, logging every outcome. Those numbers feed spreadsheets that calculate mean, median, and 90th‑percentile returns—key to working out realistic ROI brackets.

🙋♀️ FAQ
Why focus on RTP when volatility dominates short‑term outcomes?
RTP sets the ceiling for long‑term ROI; ignoring it skews any serious comparison.
Are high‑cost super bonuses ever worth it?
Only if your bankroll can endure extended downswings and you crave game‑changing jackpots.
How often should I update my bonus buy slot list?
Re‑evaluate quarterly; providers tweak maths, and new releases can topple old favourites.
