Big Bass Bonanza Slot Review: RTP, Bonuses & Features

Big Bass Bonanza is one of Pragmatic Play’s most popular online slots. Embark on a fishing adventure where scatter symbols lead the way toward success with special bonus rounds that come with the biggest catch of the game.

A simple, yet highly-entertaining slot game, Big Bass Bonanza was launched in 2020 amidst a wide array of feature-packed slots, but with much simpler gameplay mechanics and a large betting range. It’s an ideal game for beginners, yet offers gameplay and payouts that make it worth a gamble for veterans.

Key Takeaways

  • This is a highly volatile slot, featuring bonus rounds with massive payouts
  • Wilds are only available during free spin rounds
  • Autoplay features allow for fast-paced gameplay

Big Bass Bonanza Gameplay: What to Expect?

Big Bass Bonanza will have you looking for the biggest catch in the sea. Regular game rounds will hardly ever result in a profit, and you’ll be lucky to be anywhere close to breaking even before entering one of the game’s bonus rounds.

Speaking of bonus rounds, be prepared to wait patiently for scatter symbols to land on the reels. Free spins come, on average, once every 100-120 game rounds. Once you land at least three scatter symbols and enter the bonus round, you’ll be almost guaranteed to win big if the fisherman symbol appears on the reels alongside any bass symbol (if it’s a “big bass”, expect the biggest wins!).

Pragmatic Play does not disclose this slot’s hit frequency, but it’s safe to say it’s quite low. We often went 10+ rounds without landing a single payout, even if small. You can expect the same, unless you’re really lucky when you play.

Likewise, bonus rounds do not ensure wins. You depend on the fisherman symbol to appear (more than once, ideally) if you are to make any significant profit, and the symbol doesn’t appear too often. We went an entire round of 10 free spins without seeing a single fisherman on the reels.

On average, however, players can expect to see at least one, and many times they’ll be able to see 4 and trigger additional free spins to maximize their profits.

Big Bass Bonanza Pros

  • High payouts are common in bonus rounds
  • Unique gameplay mechanics
  • Very good RTP

Big Bass Bonanza Cons

  • Very low hit frequency can be frustrating
  • Lack of wild symbols in bonus rounds may cause huge losses

What Makes Big Bass Bonanza Unique?

Big Bass Bonanza’s bonus rounds with free spin multipliers really make it seem as if you were fishing for the biggest catch. The slot’s immersive gameplay will have you waiting patiently for fish worth reeling in – but when the big catch comes, it’ll make the wait worth your while.

Bonus features, Bonus Gameplay & Special Features

Big Bass Bonanza features high-paying bonus rounds. The game’s max win is 2,100x your initial bet, and although a max win is very difficult to reach, you can expect frequent 30x rounds when you trigger in-game free spins.

Symbol-wise, the game features wilds and scatters. For the rest, it works as a standard online slot. Bass symbols may look different and have different numbers associated between them, but they all count equally during non-free spin rounds.

There’s one crucial feature that helps make this game’s volatility higher than average: the slot’s wild symbol, the fisherman, only appears during free spin rounds.

Free Spins: Bonus Round

The game features a single bonus round packed with up to 20 free spins. You need to land at least three scatter symbols to activate the game’s bonus free spin round. Three symbols give you 10 free spins, four symbols give you 15, and five symbols give you 20.

Wilds with multipliers can lead to massive wins in bonus rounds

This is how the free spin rounds work, to help you get an idea of why they’re so profitable:

  • The wild symbol will collect the values of each bass symbol and add the amount to your payout total, leading to massive wins. This only happens when the wild symbol shows up while bass symbols are present on the reels as well.
  • The wild symbol substitutes every other symbol during free spin rounds. Scatters do not show up during free spins.
  • Landing a wild will result in the game’s top meter progressing. When you land four wilds during the free spin round, you’ll retrigger additional free spins.
  • You can retrigger free spins up to three times. Each time you retrigger them, you’ll get a larger multiplier (2x, 3x, 10x).

Failing to land at least 4 fisherman symbols during a free spin round will end the round in question. Payouts from accumulated wild wins will be given when the round ends.

RTP, Hitting frequency & Volatility

This highly volatile online slot makes you wait for a big win, but when it comes, it’ll feel much more rewarding than in other casino games. The game’s volatility is tied to the scarcity of free spin rounds, which are much more difficult to trigger than in other games, in proper Pragmatic Play fashion.

Here are some of the game’s basic mechanics:

  • RTP: 71% (there’s a lower RTP version of the game with 95.67%, though)
  • Volatility: High
  • Hit frequency: Not stated (Seems to be around 20%)

Best Big Bass Bonanza Alternatives

 There are some fantastic alternatives to Big Bass Bonanza that you can try out if you love the game. Pragmatic Play develops games with a similar vibe but different mechanics, and you can try them out if you love what Big Bass Bonanza offers:

The Dog House

The Dog House is almost as popular as Big Bass Bonanza. Much like the popular fishing game, it’s a highly volatile casino game that comes with a 5x4 setup and 20 paylines. The slot features a max win of up to 6,750x the amount of your bet, though, which is more than three times as much as you can win playing Big Bass Bonanza.

Gates of Olympus

Gates of Olympus takes volatility to a whole new level. It’s one of the most volatile slots created by Pragmatic, as well as one of the most popular. The game allows you to win all ways (there are no set paylines). Global multipliers accompany in-game free spins to create a massive payout potential, which is reflected on the game’s max win of 5,000x.


8 / 10


Big Bass Bonanza Verdict

Big Bass Bonanza is a slot that requires as much patience as fishing. You’ll have to sit and wait for the scatters to show up in your quest to collect the biggest payout possible. We recommend it to any player that loves high volatility slots!
