Paytable
Bonanza Billion pays for 8+ matching symbols anywhere on the grid. Payouts shown as multiples of your bet for a single combination. More symbols = bigger payout per match category.
| Symbol | 8-9 match | 10-11 match | 12+ match |
|---|---|---|---|
| 10 (low) | 0.20× | 0.40× | 1.00× |
| J (low) | 0.30× | 0.60× | 1.50× |
| Q (low) | 0.40× | 0.80× | 2.00× |
| K (low) | 0.50× | 1.00× | 2.50× |
| A (low) | 0.60× | 1.20× | 3.00× |
| Yellow citrine | 1.00× | 2.50× | 6.00× |
| Red ruby | 1.50× | 3.50× | 8.00× |

| White diamond | 5.00× | 12.50× | 25.00× |
| Golden billionaire (wild) | n/a (substitute) | n/a | n/a |
The diamond is the top-paying regular symbol. Twelve diamonds anywhere on the grid pay 25× your stake — and that's just from one cascade. Chain that into a free-spins round with stacked multiplier bombs and the math compounds fast.
Special symbols
| Symbol | Role |
|---|---|
| Golden billionaire (in top hat) | Wild — substitutes for any non-scatter, non-bomb symbol. Helps complete matches. |
| Red dynamite stick "FS" | Scatter — 4+ on the grid trigger free spins. 5+ pay an instant bonus. |
| Multiplier bomb (2×–100×) | Free-spins only — drops onto grid after a cascade, applies multiplier to next win. |
Free-spins specs
| Trigger | Free spins | Instant bonus |
|---|---|---|
| 4 scatters | 10 | None |
| 5 scatters | 10 | 5× stake instant payout |

Retrigger: 3+ scatters land during free spins → +5 spins per retrigger. No documented cap.
Multiplier bomb values: 2×, 3×, 5×, 10×, 25×, 50×, 100×.
Multiplier bomb stacking: All bombs on the grid apply their multipliers to the next winning cascade. Multiple bomb values sum (not multiply). After applying, bombs are consumed and removed.

RTP transparency
Unlike Hacksaw Gaming or NetEnt, BGaming ships only one RTP version of Bonanza Billion: the certified 96.00%. There is no 88%, no 92%, no 94% reduced variant.
This is one of the cleanest aspects of the game from a player-protection standpoint. What you see on one casino is what you get on another. The four featured casinos run the 96.00% certified default. Random offshore casinos run the same version, because there isn't a reduced version to switch to.
The Bonus Buy mode is slightly higher RTP (96.45-96.65% depending on which mode you select — BGaming offers a few buy options at different cost multiples, all clustered around 100× stake). This is the BGaming-standard pattern: Bonus Buy RTP is slightly above base RTP because the studio compensates for the variance you're taking on.
