FluxPlays verdict
Our verdict
For a bonus buyer, yes; for someone who only spins, no. In the free spins every multiplier symbol on screen is added up and applied to the whole refill sequence, so one spin can carry a round. The drawback is everything before that: multipliers never land in the base game, and three Scatters, one short of a trigger, came twice in our base session.
Who it suits
Play this if…
- Bonus buyers: the demo's buy RTP is high, and every free spin can stack multipliers
- Max-win hunters: every multiplier on screen adds to one total for the whole refill sequence
- Learners: the multiplier rule is easy to follow on screen, one total per sequence
Skip this if…
- Short-session players: the base game has no multipliers at all
- Players who dislike empty bonuses: most of our bought spins paid nothing
- You only play at a casino's lower RTP: BGaming's page shows a version well below the demo's

Bonanza Billion: Full Review
In Bonanza Billion, a single free spin can be worth the whole round, because every multiplier symbol on screen is added together and applied to everything that spin's refills won. BGaming released this 6x5 fruit-and-gem game in December 2021, before later spin-offs such as Bonanza Billion Merge Up. It suits bonus buyers who accept long stretches of nothing for the chance of one big sequence.

How Bonanza Billion works
Eight or more of the same symbol anywhere on the grid pay, in three bands: eight or nine, ten or eleven, and twelve or more. Winning symbols disappear and new ones fall in, and the refills carry on, with no limit, until no new win forms.
| Symbol | 12+ | 10 to 11 | 8 to 9 |
|---|---|---|---|
| Green diamond | $50.00 | $25.00 | $10.00 |
| Blue gem | $25.00 | $10.00 | $2.50 |
| Star | $15.00 | $5.00 | $2.00 |
| Heart | $12.00 | $2.00 | $1.50 |
| Watermelon | $10.00 | $1.50 | $1.00 |
| Plum | $8.00 | $1.20 | $0.80 |
| Lemon | $5.00 | $1.00 | $0.50 |
| Orange | $4.00 | $0.90 | $0.40 |
| Cherry | $2.00 | $0.75 | $0.25 |
Pays at a $1 bet.
The condition that decides the game: multiplier symbols exist only in the free spins. In the base game a refill sequence pays its paytable value and nothing more, so base spins top out at what the fruit and gems pay on their own.
Bonanza Billion multipliers: what they do and when they pay
Each multiplier symbol takes a random value from 2x to 100x when it lands. When a refill sequence ends, every multiplier on screen is added together, and the total multiplies the sequence's win. The values add rather than multiply, so two 10x symbols on one screen make 20x.
Our bought round shows how lopsided that can be. One free spin's refills won $0.75 between them. With the multipliers applied, the spin paid $150.00, which by the rules means the multipliers on screen added up to 200x.
Back on the base grid after our bought round, which paid $153.80 in all; a x100 multiplier symbol is still on screen. FluxPlays demo test, 1 November 2026.
Bonanza Billion free spins: how they trigger
Four or more Scatters anywhere start the free spins and also pay on their own.
| Scatters | Free spins | Scatter pay at $1 |
|---|---|---|
| 4 | 10 | $3.00 |
| 5 | 20 | $5.00 |
| 6 | 30 | $100.00 |
During the round, any three or more Scatters add five spins. Three Scatters in the base game pay nothing, and BGaming puts a natural trigger at about 1 in 395.
Bonus buy and Chance x2: prices and what you get
The buy skips the wait for the Scatters, and Chance x2 makes the wait shorter for a quarter more per spin.
| Paid option | Type | Price at $1 | Official RTP and volatility | What you get | Our test |
|---|---|---|---|---|---|
| Buy Free Spins | Bonus buy | $100 | 97.98%, High | A free-spins round started from four or more Scatters | One round: $153.80 back |
| Chance x2 | Mode, per spin | $1.25 a spin | 98.08%, High | More chance of free spins; the buy is switched off | 10 spins: $3.05 back |
The RTPs are the demo's. BGaming gives no single volatility grade, so the cells use the label explained below.
RTP, volatility and max win
The demo's rules give 98.21% for the base game, with both paid options a little lower. BGaming's own game page lists 95.97%, which means a lower version is on offer, and which one you meet depends on the casino. BGaming labels the volatility Low-high, a range rather than a grade. Review sites rate it High, so that is the value in our table.
Nothing pays beyond 15,000x the bet, at odds of 1 in 2.5 billion in the rules. A big multiplier total on a big refill sequence is the only realistic route there.

Tested on BGaming's public fun-mode demo on 1 November 2026, with FUN practice credits read here as dollars, from a 1,000.00 balance. The demo opened at 0.20 and was raised to 1.00 for every counted round. Quick spin was switched on after the buy. The 150.00 free spin is from the server reply, which gives the multiplied total, not each multiplier. Session: $212.50 staked, $221.95 back, ending at 1,009.45 on the server and on screen.
The bought round played out the way the multiplier rule suggests it can. It ran to fifteen spins after one retrigger, and twelve of them paid nothing. Two paid 40 cents. The third was the multiplier spin described above, which made up almost the whole result.
The base game paid little and often: 37 spins won something, the best of them $12.75 on spin 94, and ten paid spins with Chance x2 switched on brought no trigger. Two sessions of this size cannot measure a game whose results swing on one spin. Natural free spins stayed out of reach, so the trigger is described from the rules.
The end of our bought round: 15 free spins after one retrigger. FluxPlays demo test, 1 November 2026.
Is Bonanza Billion worth playing?
Worth it for the free spins, and the buy is the practical way to reach them. The multiplier rule gives every free spin a real ceiling, and the buy keeps almost all of the demo's high RTP. Spin it without buying and you play a fruit grid with no multipliers at all.
The rules paytable at a 1.00 bet, with the Scatter and multiplier symbols. FluxPlays demo test, 1 November 2026.
Pick Gates of Olympus if you want a pay-anywhere game rated Medium, with a 5,000x cap. Choose Bonanza Billion for three times that ceiling, if you can live with a bonus that often pays nothing until one spin pays a lot.
In the demo, buy one round and count the empty spins. It is the quickest way to see how much of this game rests on a single sequence.
Frequently Asked Questions
How do the multipliers work in Bonanza Billion?+
Multiplier symbols land only in the free spins, each showing a random value. They are added together when a refill sequence ends, and the total multiplies everything that sequence won. In our bought round, one such spin made almost the whole result.
How do you trigger free spins in Bonanza Billion?+
Four, five or six Scatters anywhere give 10, 20 or 30 free spins, and the Scatters also pay on their own. Three or more Scatters during the round add five spins. Three Scatters in the base game pay nothing and start nothing, which is as close as our base session got.
What is the RTP of Bonanza Billion?+
The demo's rules give 98.21% for the base game, 97.98% for the buy and 98.08% with Chance x2. BGaming's own game page lists 95.97%, so lower versions exist, and the casino decides which one you play. Check the rules screen in the game before you rely on the higher figure.
What is the max win in Bonanza Billion, and how is it reached?+
It is 15,000x the bet, and the rules put the odds at 1 in 2.5 billion. The only realistic route is the free spins: a refill sequence with several big multiplier symbols on screen, since their values add up before they multiply the win.
