How a round works

Bigger Bass Bonanza from Pragmatic Play and Reel Kingdom is the second game in the Big Bass series. It does what the name suggests: the grid is bigger, with five reels and four rows, and there are 12 fixed lines instead of 10. Wins pay from the left, with tackle boxes, rods, dragonflies and fish as symbols.

Fish symbols can carry cash values, shown as multiples of your stake. In the base game these values only matter if a collect feature triggers; mostly, they wait for free spins.

Features

  • Free spins: three, four or five scatters give 10, 15 or 20 free spins.
  • Fisherman wild: in free spins, each fisherman collects the value of every fish on screen.
  • Retriggers and multipliers: every fourth fisherman collected adds 10 spins and raises the collection multiplier (2x, then 3x, then 10x).
  • Bigger grid: the extra row means more fish and more fishermen per spin.

The top win is 4000x the stake, higher than the original’s.

RTP and volatility

The RTP in our data is 95.67%. Pragmatic Play supplies more than one version, so check the paytable in your casino’s game.

High volatility here works the same way as in the original: the base game drifts, free spins carry the value, and within free spins the multiplier levels make the difference. The extra row makes good rounds a bit more frequent than in Big Bass Bonanza, and the cap is higher, but sessions still swing.

Honest tips

  • Free spins can pay almost nothing. A round with fishermen but no fish, or fish but no fishermen, is common.
  • The 10x level is rare. Most rounds finish at the first or second level.
  • Choose your version. The Big Bass family runs from gentle (original) to very swingy (1000 versions). This one sits near the gentle end.
  • Use free spins offers carefully. Read the wagering on any spins winnings.
