Bigger Bass Bonanza

Quick verdict

A roomier Big Bass that rewards patience. Our finished rounds paid 32.5x to 103.5x at £1.20, and the best one was past 166x when we had to leave it, helped by five fish paying their combined values as a line win. The 4,000x fish rolled by more than once but was never collected.

Our Demo Rounds

Two spins into our free spins, a fisherman dropped onto the fifth reel and hauled in £114 from four fish in one go. That was 95 times our £1.20 stake, landed 183 spins into the session, and it carried the round to £124.20 by the final spin. We played the free Bigger Bass Bonanza demo above in Pragmatic’s UK version. We read every figure below from our own screens or the in-game rules.

The fisherman’s card reads £114 with eight spins left, the total of the four fish in view.

The bigger reel set is the first thing you notice. Five reels now run four symbols deep, so twenty positions fill on every spin instead of fifteen, and the fish sit on yellow and pink tiles with their cash value printed along the bottom edge, big enough to tot up before he arrives.

The UK build has no autoplay or turbo. A base spin settled in about four seconds, and ten free spins took a little over a minute, banners included.

Bigger Bass Bonanza RTP and Max Win

Our demo’s rules list a theoretical return of 96.71% and a medium volatility rating, which the game describes as a steady payer whose wins can run anywhere from low to very high. Our rounds matched that. The ones we saw through paid 32.5x, 91x and 103.5x the stake, and another had climbed past 166x with eight spins still to come.

The top prize is 4,000 times your bet. Reach it inside a free spins round, and the round stops on the spot, pays the capped amount and throws away whatever spins were left.

The game has 12 fixed paylines, each read from the leftmost reel across. The rules list stakes from 12p up to £240 a spin, though no UK casino may take a slot stake above £5, and the ceiling drops to £2 for anyone under 25. Pragmatic’s international build, the one our hub embeds, adds Autoplay and a hold-to-turbo option. Neither build sells a way into the bonus.

The fish row is the odd one out. Five fish on a payline don’t pay a fixed prize, they pay whatever cash values they’re carrying, added up. We saw this in the base game when five fish lined up on line 4 and paid £22.80, exactly the sum of their tags.

Bigger Bass Bonanza Free Spins

Land three scatters for 10 free spins, four for 15 or five for 20. Every fish takes a random value on each spin, from 2x to 4,000x the total bet, and during the round any fisherman that lands collects every one in view. The fisherman is the wild; he only appears once the free spins begin, and he substitutes for every symbol bar the scatter.

A strip across the top keeps count of fishermen. Every fourth adds 10 spins and raises the fish’s value, doubling it after the first retrigger, tripling it after the second, and multiplying it by ten after the third. No retrigger comes after that. When only one fisherman shows at the end of a free spin, fish can also be dropped onto the reels at random.

Our best round came from a different direction. With two spins left, the fourth fisherman arrived with no fish on the screen, so he collected nothing but still lit the x2 stage.

Two free spins left and nothing to catch, but this fourth fisherman unlocks the +10 spins x2 marker at the top.

Then, on the very last spin of the batch, five fish landed across the top row and paid £86.40 as a line win. An Epic Win banner started its count below £6, and the round jumped from £65.40 to £151.80 before the doubled spins had even started.

No free spins left on the counter and five fish on the top row, worth £86.40 together. Line 3 paid all of it.

The x2 stage had reached £199.80 with eight spins to go when our session ended, so we never saw that round’s final total.

A later round did run to the finish after a retrigger. It took 304 spins to arrive, sat on £84 when the fourth fisherman came in, and a speedboat raced across the screen to open the x2 spins. Those added £25.20 more, and the round closed on £109.20.

Back to the base game, with £109.20 from the retriggered round on the win meter and FREE SPINS COMPLETED beneath it.

Waits for the trigger ran from 38 spins to 304 across our six bonus rounds, and the smallest round we saw finish paid £39. We also saw £4,800 fish, the 4,000x value, roll past on the spinning reels, but never with a fisherman there to collect.

Bigger Bass Bonanza vs Big Bass Bonanza

Our Big Bass Bonanza demo page covers the original, and both share an RTP of 96.71% plus the same 2x, 3x, and 10x retrigger ladder. The differences are all about size.

  • The original runs five reels of three rows with 10 lines. This one adds a fourth row and two more lines.
  • Big Bass Bonanza is rated low volatility, and caps wins at 2,100x. The sequel is medium and caps at 4,000x.
  • Fish values top out at 2,000x in the first game and 4,000x in this one.
  • Five fish in the original pay a fixed 20x. Here they pay their combined cash values.

Two other larger editions appear on Pragmatic’s site. Bigger Bass Splash lists a 96.50% RTP, fish worth up to 5,000x and as many as five modifiers before the feature starts, much like our Big Bass Splash free demo. Bigger Bass Blizzard Christmas Catch gives the set a winter theme, with snowmobiles among the symbols, and lists 96.08%.
