Big Bass Bonanza, 1000 and Splash: what is the difference

Online casino
Oct 29, 2026

Big Bass Bonanza started one of Pragmatic Play's biggest series. Every version shares one idea: in free spins, the fisherman collects money fish. What changes is the symbol values, the modifiers and the win ceiling. We compare three popular versions using data from the provider and the IPU.BET catalogue. This is a look at mechanics, not a strategy: every spin is random.

Big Bass Bonanza: where the series began

A 5x3 grid with ten paylines. The main action is in free spins: three, four or five scatters award 10, 15 or 20 free spins. In the bonus, fish with money values of up to 2,000x the bet land on the reels, and the fisherman wild collects every visible value. Every fourth wild adds 10 free spins and raises the collection multiplier: 2x first, then 3x, then 10x. The provider lists 96.71% RTP, one of the highest in the series.

Big Bass Bonanza 1000: a 20,000x ceiling

Same formula, different balance: money symbols are worth up to 1,000x, and the provider lists a maximum win of 20,000x the bet. If two scatters land, the game can add a third at random and trigger the bonus. Retriggers and the 2x, 3x and 10x multipliers work as in the original. RTP is lower: 96.51%.

Big Bass Splash: modifiers before the bonus

Free spins and collection multipliers are the same, but before the bonus starts the game adds 0 to 5 random modifiers, such as extra money symbols, wilds or spins. Money symbols are worth up to 5,000x, and the IPU.BET catalogue lists the maximum win as 5,000x the bet. The provider lists 96.71% RTP.

RTP differs across the series, and it matters

The provider lists 96.71% for Big Bass Bonanza and Splash and 96.51% for the 1000 version. On top of that, the same game can ship in several RTP variants, and the casino picks which one to run. Check the RTP in the game's own info screen. We explained how in why the RTP of one slot differs between casinos.

Which version to choose

  • Big Bass Bonanza, if you want the original formula and the highest RTP in the series.
  • Big Bass Bonanza 1000, if you are ready for sharper swings in exchange for a 20,000x ceiling.
  • Big Bass Splash, if you like random modifiers before the bonus.

All three versions are highly volatile. Set a session budget in advance and do not chase losses.
