An Introduction to Bass Boss

Bass Boss is a fishing-themed slot game set on a 5×4 grid. The game is based on a thrill-seeking fisherman in search of his next big catch. The action takes place underwater and there are three bonus features to help you during the trip. 

There’s nothing fishy about this game, despite its high volatility. In fact, you can hook some generous payouts thanks to the solid Return To Player rate of 95.57%.

Set off on an exciting fishing adventure and reel in big wins up to 4,835x your stake in Red Tiger Gaming’s Bass Boss.

Betting and Layout

Bass Boss is set on a grid with five reels and four rows. Its translucent reels are set underwater against submerged rocks and surrounding marine flora. The star of the game, the Bass Boss himself, is not left out either as he is seen lowering his fishing line into the water.

Like other online slots by Red Tiger Gaming, Bass Boss is a visual masterpiece. The reels are adorned with symbols including a golden fishing boat, a purple cooler, a fishing hat and a fishing line. They are the game’s higher-paying symbols. Additional icons include fish of varying colours and playing card symbols from A to ten. The soundtrack is a fast-paced, bubbly tune that is reminiscent of an action movie. 

The Bass Boss RTP is 95.70% and it is a high volatility slot. There are 10 fixed paylines and each spin requires a bet between 0.10 credits and 20 credits. As you play this slot at our regulated casinos, you can earn the maximum obtainable win of 4,835x your stake.

Gameplay and Features

You can secure a win by landing a combination of three identical symbols on adjacent reels, beginning with the leftmost position. Red Tiger Gaming has introduced a special twist to this game, offering three unique ways to earn higher wins. They include the Catch, Nudge, Enhanced Bait and Free Spins. 


The Catch feature is launched during or after the free spins round. Here, the Bass Boss drops his fishing line into the water and a fish attaches itself to the hook. There are four different fish of varying colours and multipliers. 

Depending on the multiplier value of the fish, you can earn a Nice Catch, a Big Catch, a Super Catch or a Mega Catch. During this round, the hook can be nudged above or below the rows to collect additional fish icons.

Enhanced Bait

This is the most valuable feature in the game. It applies multipliers worth 2x, 3x, 5x or 10x during the Catch or Nudge round. Every time the hook catches a fish, the multiplier counter at the top of the reels advances one step further. The counter progresses to the next multiplier value after collecting eight fish icons, this continues until the maximum multiplier of 10x is reached.

Activate the Free Spins feature when you land three or more scatter symbols on the reels. You’ll find more detailed information about this game later in our slot review.

Regular Symbols

Card icons from A to 10 are the game’s low-paying symbols. In line with the theme of the game, the colourful card symbols are adorned with fishing accessories including hooks, bobbers, bait and knives.

The better-paying symbols include a golden boat, a purple fishing cooler, a green fisherman hat and a fishing reel. A golden fishing boat is the slot’s highest-paying symbol.  

Scatter Symbols

The scatter is a golden trophy with “Contest Spins” boldly written on it. Landing three or more Contest Spin symbols activates the Free Spins round. 

  • 3 Scatters: 10 free spins
  • 4 Scatters: 15 free spins
  • 5 Scatters: 20 free spins

Wild Symbols

The casino software Red Tiger Gaming usually includes wild symbols in their slots but this game has no such feature. However, they compensate for this with several lucrative symbols, as explained elsewhere in this Bass Boss slot review.

Bass Boss Free Spins

The Free Spins round is called Contest Spins. Like most video slots, this feature launches when at least three Contest Spins icons appear anywhere on the grid. There are four free spin levels and at the end of each round, you can earn up to 20 free spins.

How to Win at Bass Boss

To secure a win, you need to collect a combination of three or more similar icons. These symbols must appear on any of the ten active paylines, beginning with the leftmost reel. 

Your payout amount depends on your bet size and the value of the icons that make up the combination. You can earn higher wins by activating the Free Spins round or other bonus features already discussed in this Bass Boss review.
