Big Bass Bonanza: 96.71% published RTP

Big Bass Bonanza is a Reel Kingdom title and a published return of 96.71%. Operators can legally ship a reduced-RTP configuration of the same title without disclosing it in the lobby, so the paytable in the game's info screen is the figure to trust.

We haven't field-tested a per-operator build for this title yet. Until we have, treat the published return as the ceiling, not a guarantee at any specific casino.

Why it is on the list

Big Bass Bonanza is built by Reel Kingdom and distributed by Pragmatic Play, whose game page is the one we read. It is on the list because it is the clearest medium-volatility design here, and its whole game is one idea: in the bonus round, money symbols carry cash values, and wilds collect them. Pragmatic's page says money symbols with values of up to 2,000× can land in the bonus game. The base game exists to land scatters, and the free spins are where the collecting happens.

How it plays

From the studio's game page: three, four and five scatters trigger the feature with 10, 15 and 20 free spins respectively. During the feature, wilds collect all visible money symbols. Every fourth wild collected retriggers the feature with 10 more spins, first with a 2× multiplier, then 3×, and a 10× multiplier on the third retrigger. The round therefore builds as it goes: the longer it runs and the more wilds land, the larger the multiplier applied to each collection. A round that reaches the third retrigger is the outcome the ceiling depends on.

The maths

Pragmatic's game page publishes one return for this title: 96.71%. The page does not say whether lower configurations are licensed, so the in-game paytable is the check on the build you are playing. Volatility is rated medium, and the max win is 2,100× the bet; neither figure is stated on the studio's game page, so confirm them in the in-game rules. A medium rating against a 2,100× cap points to a steadier ride than the tumble slots on this list.

Who it is for

Players who want a calmer session than the high-volatility titles on this list, and who like a bonus round that visibly builds. The 2,100× cap is the trade-off. If you want more variance on a Pragmatic title with a single published return, Gates of Olympus, also on this list, offers a 5,000× max win at very high volatility and 96.5%.
