Bass Boss slot review

You won’t be able to help smiling when you see the fisherman who leads the Bass Boss slot. He is so obviously enthused by his hobby, a massive grin on his face as he casts his line and pulls in the fish that will hopefully lead you to a big total win. This extremely charming 5x4 slot is full of fun graphics and features that elevate it far beyond its ten paylines.

All about the bass

There are lots of fish in the sea, but there is something about the short, punchy sound of ‘bass’ that makes it ideal when naming slots. From the title alone, Bass Boss doesn’t sound that different from many other fishing slots; however, it has distinctive graphics and a unique atmosphere to make it stand out from the crowd.

You can hear the lapping water, the birds screeching above, and other natural sounds. When you press the spin button, the music picks up as you hope for those elusive winning symbols to land.

Reel them in

Fishing not only has a practical purpose but is also an ethos for life. You can see this in the Bass Boss slot, where the bold 3D fisherman bobs in a narrow space at the top of the screen whilst the blue bubbling waters stretch down beneath him. The reels are laden with not only various fish but also boats, tackle, and other essential equipment.

Bass Boss RTP and variance

We have been warned that the Bass Boss slot may be one of those games where casinos can change the RTP. We spun it with a figure of 95.7 per cent, which is lowish but not too low compared to other slots.

What may make you pause, unless you are a risk-loving high roller, is the high variance. Slots with high variance are volatile, swinging between big wins and long periods of drought. 

How to play Bass Boss

Cast your line and reel it in:

  1. Enjoy the opening animations first, which are a lot of fun.
  2. You will find the settings in the top corner, including the sound and full-screen mode.
  3. There is also a menu leading to the paytable and help page. If the paytable looks familiar, it is because it is part of the loading screen.
  4. Make sure you understand the gameplay, then head back to the reels. Don’t spin without adjusting your bet, even for demo play.
  5. You may see your current bet, in which case click to see more options or use the plus and minus buttons if available. 
  6. Turbo and autoplay don’t always show up, but they will be in the bottom corners if they are available. Autoplay requires a loss limit, so you have to be responsible. Timeout and self-exclusion functions are available.
  7. Play, have fun, and know when to stop. 

How to win at Bass Boss

As you may have guessed, you need to catch fish! They pay instantly when you find them; however, other winning symbols, such as the card symbols and fishing gear, need to land in combinations of at least three across one of the ten paylines. The biggest sequences are five symbols, reflective of the five reels that span four rows rather than the three of most slots.

Top wins

  • There are five lower-paying card symbols and five themed symbols with higher payout potential. The top value among them is the 30x win multiplier for five fishing boats.
  • When it comes to the fish, which pay instantly as soon as you catch them, the biggest of all - both in size and value - is worth a 200x multiplier.
  • The max win is 4,835x. 
  • Don’t forget the added potential of the free spins and multipliers. Read the bonus section of our Bass Boss slot review to find out more.

Bet range

The minimum bet is 0.20 and the maximum is 20.00.

Bass Boss bonuses

As we have already mentioned, the Bass Boss bonus features include free spins and lots of multipliers. Let’s explore:


Could the Bass Boss slot really revolve around fishing without catching fish? The fisherman casts his line randomly and collects all the fish in the row on which it lands.


Sometimes, when the first cast is unsuccessful, the fishing line can be nudged into the next row and try again.

Improved bait

This is another way to add a win multiplier: afloat attached to the fishing line applies 2x, 3x, 5x or 10x to every caught fish.

Contest spins

It takes the scatter symbol to trigger these special free spins:

  • 3 scatters = 10 spins.
  • 4 scatters = 15 spins.
  • 5 scatters = 20 spins.

During this feature, the fisherman’s hook stays in the water and moves between the rows. This means more chances to catch fish, which will help to fill the contest progress bar. This leads to ten more spins and a float multiplier of 2x, 3x, 4x or 10x. The maximum number of additional spins is 40.

Bass Boss review: our verdict

We have played a lot of fishing slots, but few like this. The character and personality of the fisherman, the ability to catch fish in addition to filling paylines, the numerous additional multipliers and the extra features in free spins add up to a special experience compared to any other video slot.

What is the RTP of the Bass Boss slot?

We have played plenty of Red Tiger slots, so we know they don’t all reach the 96 per cent RTP threshold we prefer and often have changeable averages. The Bass Boss slot is a lot of fun, so don’t let the slightly low 95.7 per cent RTP and risky high variance discourage you. You can spin in free demo mode here at Slots Temple to ease your nerves.

How do you catch fish in Bass Boss?

Fish appear in the base game and the free spins, and it is random as to whether the fisherman will cast his line in the right place. Land a fish and it pays instantly, with no need for a payline. Nudges and bait multipliers improve your chances through extra turns or bigger wins.

Does the Bass Boss slot have a free spins bonus round?

Yes, find the scatter symbol three or more times to trigger between 10 and 20 free spins. These are not just any free spins, as they are part of a contest: catch more fish and you will fill the meter, bringing you yet more free spins and multipliers to increase your prize.
