Bonanza Trillion is BGaming’s 2025 follow-up to Bonanza Billion, released on 11 September 2025. It keeps the 6×5 “pays anywhere” grid with tumbling wins, but changes almost every number around it: a higher RTP of 97.17%, free spins more than twice as often, multipliers up to x500 that also appear on regular spins – and a much lower ceiling of 5,000x. This review explains what those changes mean in play.

How the base game works
Symbols pay according to how many of the same kind are on the screen, wherever they land. Winning symbols are removed, new ones fall in, and the cycle repeats until no new win forms; the payout is credited after the last cascade.
The big change from the original is that multiplier symbols can land on regular spins. Each carries a value from x2 to x500. They stay on the screen until the cascades finish; then their values are added together and the sum multiplies the total win of that spin. In Bonanza Billion, multipliers existed only in free spins.
BGaming’s figures set the rhythm: a winning spin about once in 3.19 spins, and a bonus about once in 163 spins – roughly six bonuses per 1,000 spins on average.
Free spins: a fixed 15 and a growing multiplier
Four or more scatters anywhere pay out and start 15 free spins. Unlike Bonanza Billion, the number of spins does not depend on how many scatters land. Three or more scatters during the round add five spins.
Inside free spins the multipliers work differently from the base game: the values from winning spins are added into one total multiplier, which then applies to later winning spins in the same round. A round that collects several multipliers early can therefore make every later win much larger. One third-party review (AboutSlots) adds details BGaming does not state – colour-coded multiplier tiers and a rule that the total applies only when a new multiplier lands – so treat the game’s own rules screen as the final word.
Chance x2 and the three bonus buys
- Chance x2 raises the stake slightly and makes free spins more frequent. It cannot be combined with a bonus buy. One review puts the surcharge at 25% of the bet; BGaming does not publish it.
- Bonus buy comes in three versions, each with 15 free spins: a regular round, a round that starts with a x50 multiplier and one that starts with x100. BGaming shows the prices in the game only; AboutSlots lists them at 100x, 300x and 500x the bet, and Best Slots Journal gives a range of x100–x500.
The two upgraded buys give the round a head start on its total multiplier rather than more spins. If those third-party prices apply at your casino, they are the most expensive way into the game’s 5,000x ceiling and suit only budgets planned around a few attempts.
Bonanza Trillion vs Bonanza Billion
| Bonanza Billion (2021) | Bonanza Trillion (2025) | |
|---|---|---|
| RTP | 95.97% | 97.17% |
| Hit rate | 1 in 2.59 | 1 in 3.19 |
| Free spins rate | 1 in 395 | 1 in 163.2 |
| Free spins awarded | 10 / 20 / 30 for 4 / 5 / 6 scatters | 15 for any 4+ |
| Multipliers | x2–x100, free spins only, summed per tumble sequence | x2–x500, base game and free spins; one growing total in free spins |
| Bonus buy | One option | Three options (regular, start x50, start x100) |
| Max win | 15,000x (€180,000) | 5,000x (€250,000) |
In short, Trillion trades the 15,000x ceiling for a higher RTP and much more frequent bonuses. Billion is the better pick for players chasing the biggest multiple of the stake; Trillion for those who want to see free spins more often. Read our Bonanza Billion review for the original’s details.
Other games in the series
BGaming has continued the line with Bonanza Billion Xtreme (March 2026, RTP 96.97%, very high volatility, up to 20,000x) and Bonanza Billion Merge Up (September 2026, RTP 97.04%, up to 15,000x). Of the four, Trillion has the highest RTP and by far the most frequent free spins, but the lowest maximum win.
Trillion’s RTP, cap, free spins rate and multiplier rules first appeared in BGaming’s 2023 Gemhalla, which also publishes its buy and Chance x2 prices.

Poor fit: players hunting five-figure multiples of the stake – the 5,000x cap is a third of the original’s.[/wpremark]
Verdict
Bonanza Trillion is a deliberate rebalance of the 2021 original: 97.17% RTP, a bonus roughly every 163 spins and multipliers up to x500 that now work in the base game too. The price is the 5,000x ceiling. For players who want frequent bonuses it is the stronger game of the two; for the biggest multiple of the stake, Billion still has the edge.
