A spin can contain several cascades
Bonanza Billion does not use fixed paylines. BGaming describes its win format as “Pays Anywhere”: matching symbols are counted across the screen regardless of position. When a win forms, those symbols disappear and the remaining symbols move down. New symbols fall into the empty spaces, and the process repeats until no further win forms. Explore 22Bet
This means the first arrangement is only the start of a possible sequence. A cascade is still part of the same spin; the provider says the total is added after the refill sequence ends. The game page describes this as the studio’s first title with cascading reels.
Example: one spin, then a refill
Suppose matching symbols pay on the opening layout. They clear, symbols above drop, and new symbols fill the gaps. If the new layout creates another match, a second cascade follows. If it does not, that spin’s sequence ends. No extra wager is described for each refill in BGaming’s rules; the displayed game rules control the version in use.
During Free Spins, multiplier symbols can remain through the refill sequence. The game adds the multipliers shown on screen at the end of that sequence and applies the combined value to the total win. This is a feature rule, not a way to forecast how often such a sequence appears.
Scatter count sets the Free Spins total
Four Scatters anywhere on the screen award 10 Free Spins, five award 20, and six award 30. Three Scatters during the Free Spins round add five more spins. BGaming lists a Buy Bonus option and a separate Chance ×2 feature. The latter raises the bet while increasing the chance of seeing four or more Scatters in the base game; it is disabled while Buy Bonus is active.
The price of a bought feature is shown in the game’s own button and changes with the selected stake. We do not publish a fixed GBP cost because the provider’s page describes a stake-adjusted price, and no specific operator build is attached here.
How to read the published numbers
BGaming lists 95.97% RTP, a “Low-high” volatility label and a maximum multiplier of 15,000×. The studio’s public page does not define “Low-high” as a single volatility band, so we preserve its wording. RTP is a theoretical long-run value, not a session forecast. The maximum multiplier is a cap, not a likely outcome.
The public product page does not list a reel-and-row layout or a stake range in GBP. Those fields are left out. If the game opens in a casino lobby, its own information panel takes priority for the installed version. Explore 22Bet
