Bigger Bass Bonanza slot review
Bigger Bass Bonanza is Reel Kingdom’s 2021 sequel to Big Bass Bonanza, released through Pragmatic Play. It adds a fourth row and two paylines to the original, for five reels, four rows and 12 fixed lines, and raises the top fish and the maximum win to 4,000x stake.

How Bigger Bass Bonanza plays
Wins pay left to right along the 12 lines. The boat is the top symbol and pays from two in a row; every other symbol needs three or more. Fish are money symbols showing cash values of 2x to 50x stake, with a rare 4,000x fish. In the base game those values count only when five fish land on one line, which pays the total of all five. That rule is new to the Bigger format: in the original Big Bass Bonanza, five fish pay a fixed amount. There are no wilds in the base game.
Free spins and the fisherman meter
Three, four or five scatters trigger 10, 15 or 20 free spins. The fisherman wild then appears on all five reels, and every wild that lands collects the value of every fish in view. If a spin ends with a single wild on screen, fish can be added in random positions.
Each wild also fills a meter above the reels:
- 4 wilds: 10 more free spins, with fish values collected at 2x.
- 8 wilds: 10 more free spins at 3x.
- 12 wilds: 10 more free spins at 10x, the final level.
The round ends early if wins reach the 4,000x cap.
