How to play Bass Boss mobile slot

Your new best friend is the fisherman at the top of the reel who may catch up to 4,835x your bet in this Bass Boss slot by Red Tiger Gaming slot.

Will you conquer these massive 5×4 reels with only 10 paylines? It’s exciting to see this sport-themed slot spin, with the background of the deep blue highlighting fish, tackle, boars, fishing hooks, and high card symbols. None of them matter; they are purely decorative.

Bass Boss slot is a high variance game with an RTP of 95.7% where the trick is to catch the Bass Fish symbols on the reel using the Hook by the fisherman on the left. Like the claw machines at the arcade, only you have to pay for each spin, and the claw doesn’t always come down.

Does it sound a little frustrating? Sure. But no more so than the Big Bass Bonanza slot, on which this casino game is based. If you loved one, you’ll almost certainly love this modern retelling.

How to win big in the Bass Boss slot

Randomly the fisherman will throw his hook down the reels and catch all the fish in that row. Sometimes he nudges up and down and catches more than one fish, but it’s rare – usually, it’s somewhere around 2x your bet, sometimes as low as 0.5x, and sometimes as high as 200x your bet.

On rarer occasions, that hook may have a multiplier x2 to x10, turning a 200x your bet fish to a 2,000x your bet win. Not bad, right? And definitely more interesting than in the Fishing Frenzy Big Catch slot.

But you want to catch at least 3 contest free spin scatter and get 10 free spins to compete to catch the most amount of fish. Not the biggest; what you need is sheer volume to get you close to the top win of this Bass Boss video slot.

Is the Bass Boss slot any good?

That depends on your expectation of the free spins. This is a competition, and there are multiple levels. Each time you catch 8 or more fish, you get another 10 spins and increase the hook’s multiplier from 2x to 3x, 5x, and finally 10x.

You can play a maximum of 40 free spins, with the last 10 spins giving you a 10x multiplier on all the fish you catch. Which could be little piddly fish or big huge 200x your bet fish.

Either way, if you are hoping to get anywhere near the Big Bass 4,835x your bet max win, you will need to become the best fisherman around… and for the most part, you don’t often get beyond a 2x multiplier.

That’s when you should remember that Bass Boss mobile slot is as volatile as the rest of the Big Bass games. So watch your budget and use the 0.20 to 20 a spin betting range wisely and enjoy a fun fishing game.

Bonus Features

Fish Symbol and the Fisherman: The fish symbol land anywhere. They can't create win lines, but each has instant cash win amounts.

  • Grey Fish with either 2x or 5x
  • Blue Fish with either 10x or 15x
  • Green Fish with either 30x or 50x
  • Orange Fish with either 100x or 200x

The fisherman above the reels may randomly drop his hook on the water over any of the 4 rows. If his hook is on the same row as the fish, he collects all the fish in that row on that spin. You then win the instant cash prize.

Nudge: If the fisherman casts on a row where there's no fish, or after a successful catch, he may move the hook of his fishing line to another row to collect additional fish.

Multipliers: The fishing hook may randomly have an x2, x3, x5, or x10 multiplier added, which is then applied to any fish you catch.

Free Spins: Landing 3, 4 or 5 Contest Spins scatter will trigger 10, 15, or 20 free spins bonuses.

During the free spins, the fisherman's hook is always in the water, trying to catch fish. The game also tracks how many fish he catches.

For every 8 fish he catches, you get +10 more free spins, and you get a multiplier on the hook - first x2, x3, x5, and finally x10.

There's a maximum of 4 retriggers or 40 extra contest spins.


  • Fun fishing theme
  • Low 0.20 minimum bet
  • Free spins with multipliers provide biggest wins


  • Low 20 max bet
  • Too high variance for some

Bass Boss Review Conclusion

The free spins may be a little frustrating, but that fishing for you. Sometimes you catch sardines, sometimes tuna, and sometimes you go home hungry. You just have to hope you are fishing on the right day at the right time.

Bass Boss slot online gives us a nice twist on the Big Bass Bonanza genre, thanks to its inventive graphics, a modern design, and wins of over 4,800x your bet.

Fans of the Bigger Bass Bonanza slot will appreciate a progressively richer free spin bonus whilst still loving that there's only one feature you need to look for - the paytable is just there to fill the reel.

It doesn't reinvent the wheel, but it's a great addition to your favourite casino's Red Tiger Gaming slots portfolio.
