Bonanza Billion launched late 2021 and holds the highest max win in BGaming's entire portfolio: 15,000x. To put that in perspective, it beats Aztec Magic Megaways (12,960x), Aztec Magic Bonanza (10,200x), Wild Cash X9990 (9,990x) and Book of Cats (8,202x). If you're chasing BGaming's single biggest number, this is where you'll find it.
It runs on a 6x5 "Pay Anywhere" cluster pays format with random x2 to x100 multipliers in Free Spins. RTP sits at 96%, volatility is high. This is a slot built to chase the max win — not one for long, low-budget sessions.
TL;DR — Bonanza Billion in 4 points

Why Bonanza Billion dominates BGaming's max win chart
Here's how it stacks up against the top max wins across BGaming's 16-slot portfolio:
| Slot | Max Win | BCE Score |
|---|---|---|
| Bonanza Billion | 15,000x 🏆 | 9.2 |
| Aztec Magic Megaways | 12,960x | 9.0 |
| Aztec Magic Bonanza | 10,200x | 9.0 |
| Wild Cash X9990 | 9,990x | 8.5 |
| Book of Cats | 8,202x | 9.1 |
| Elvis Frog TrueWays | 5,000x | 9.3 |
| Big Atlantis Frenzy | 4,320x | 8.7 |
Bonanza Billion pays out 15% more than Aztec Magic Megaways and 47% more than Aztec Magic Bonanza. Mathematically, it's the max win ceiling of BGaming's entire portfolio.
Pay Anywhere — how it works
The classic cluster pays system, applied here:
- 6x5 grid = 30 cells
- No paylines — matching symbols count anywhere on the grid
- A minimum of 8 identical symbols on the grid triggers a win
- The more symbols land, the higher the payout climbs
- Refilling reels: winning symbols vanish and new ones drop in (a cascade)
- A fresh combination triggers another cascade — and potentially a chain reaction
This is the same format used by Sweet Bonanza (Pragmatic, 2019) and Aztec Magic Bonanza (BGaming, 2022). It's the dominant format across the modern slot market.
x2-x100 random multipliers — the road to 15,000x
This is the signature feature during Free Spins:
| Cascade | Random multiplier | Effect |
|---|---|---|
| Cascade 1 | x2-x100 (random) | Applied to that cascade's win |
| Cascade 2 | x2-x100 (random) | Stacks with the previous one |
| Cascade 3+ | x2-x100 (random) | Stacks further |
Several chained cascades with stacking multipliers are the main path to 15,000x. Landing a stacked x100 is rare, but visible enough to keep the session addictive.
Bonus buy — available
Bonanza Billion offers a bonus buy (the exact cost depends on the operator, typically around 100x the stake). It guarantees direct entry into Free Spins with the cumulative multiplier system already active.
⚠️ Bonus buys are banned in the UK. For larger bankrolls chasing the 15,000x, it's the most efficient path.

Strategies by budget
Small budget (< €200)
Bonanza Billion isn't ideal for this budget — brutal variance combined with a max win far removed from the base game. Stick to €0.20-€0.40 bets and aim for a natural Free Spins trigger without expecting too much. A better option for smaller budgets: Sunny Fruits Hold and Win (Playson, max 1,193x but a 20.69% hit rate).
Medium budget (€500-€1,000)
Mix it up: 70% base spins at €0.40-€1 plus 30% buys at €0.30-€0.50. Buying guarantees access to the stacking multiplier system. Short, intense sessions are recommended.
Large budget (€2,000+)
Bonanza Billion is optimal at this budget. Buy at €1-€2 (assuming a €100-€200 cost per buy) to chase the 15,000x. At a €2 stake, the theoretical maximum jackpot is €30,000. A minimum of 10-15 buys is recommended to absorb the high variance.
