Bigger Bass Bonanza is the second game in Pragmatic Play's Big Bass series. It expands the grid to 5x4 with 12 paylines and raises the max win to 4,000x, while keeping the same fisherman collect bonus. Volatility is higher than the original. It suits you if you liked Big Bass Bonanza and want a bigger grid and higher ceiling without a completely new set of rules.

How does Bigger Bass Bonanza work?

You play on 5 reels and 4 rows with 12 fixed paylines, and wins pay from left to right. Card royals are the low pays, while fishing items and fish are the higher pays.

Fish symbols carry cash values that pay out in the bonus. Stakes go from 0.12 to 240 per spin.

Compared with the original Big Bass Bonanza, the extra row and two extra paylines give more chances to line up symbols on each spin. The fish symbols still only pay through the fisherman in the bonus, so the base game is mainly about steady line wins while you wait for scatters.

What are the Bigger Bass Bonanza bonus features?

Three, four or five scatters award 10, 15 or 20 free spins. During the round, fisherman wilds collect the values of all fish on screen.

Every fourth wild collected on the meter retriggers the round with 10 more spins and raises the multiplier for fish values: 2x on the first retrigger, 3x on the second and 10x on the third. No further retriggers are possible after that. The bonus ends if the 4,000x cap is reached.

Fish values are multiplied by the current level, so the same fish worth 5x your bet pays 50x once the 10x level is reached.

Is Bigger Bass Bonanza worth playing? RTP and volatility explained

The top RTP is 96.71%, with lower settings of 95.67% and 94.62% offered to casinos. Always check which one is live.

Volatility is high, a step up from the original. The 4,000x max win needs the 10x level plus valuable fish, so many bonuses end with smaller amounts.

If you are new to the series, it can help to start with the original Big Bass Bonanza at its lower volatility, then move on to this version once you know how the fisherman meter works. The rules are almost identical, so the step up is about risk rather than learning new features.

Tips before you play Bigger Bass Bonanza

  • Check the RTP in the game info before you deposit.
  • Note the 0.12 minimum, which is slightly higher than the original's 0.10.
  • Try the demo to see how the bigger grid changes the pace.
  • Note that the bonus ends immediately if the 4,000x cap is reached.
