Big Bass Bonanza Features

Big Bass Bonanza is all about the free spins round. This can be triggered by landing 3 or more scatters to trigger up to 20 free spins. The amount of free spins depends on the amount of scatters that trigger the feature such as:

  • 3 scatters award 10 free spins
  • 4 scatters award 15 free spins
  • 5 scatters award 20 free spins

During free spins, each wild symbol collects all the values from the money symbol on the screen. These are collected and every 4th wild retriggers the feature to award 10 more free spins and a multiplier. This starts with x2 multipliers for the first trigger, x3 multiplier for the second and x10 multiplier for the third retrigger.

Big Bass Bonanza Review

Within the world of iGaming, there are two big fishing slots that reign supreme. The first is Blueprint Gaming's Fishin' Frenzy Megaways and the second is Pragmatic Play's Big Bass Bonanza.

Developed through Pragmatic Play's Reel Kingdom, Big Bass Bonanza plays on 5-reels with 10 paylines and focuses on a charming fisherman trying his best to gain the biggest catches.


As the slot opens up, players are transported to the bottom of the ocean surrounded by wonderful plant life and bait. On the reels, there are various fish and fishing rods to match the theme. The face of the slot is the fisherman who resembles Gonzo from Gonzo's Quest Megaways which makes the slot feel more personal.

Sadly, there is no animation throughout the slot aside from winning animations which is a little disappointing. Thankfully, the music is very uplifting throughout spins and creates the perfect atmosphere for the slot.


The beauty of Big Bass Bonanza is that the gameplay is straightforward and features simplistic gameplay. This makes the slot perfect for beginners to online slots or for players who want something easy to pick up and play.

At the bottom of the screen, there is a spin button to the right followed by the bet level buttons. To the far left, there are other settings such as sound and paytable information in case this is needed.

Win Potential

Big Bass Bonanza starts off strong with an incredible RTP of 96.71% which is high for an online slot. In addition to this, there is a high volatility level leading to larger wins but less frequently.

The biggest wins in this slot come from the free spins round which can deliver wins of up to 2,100x your stake. Whilst this isn't anything crazy special, it's a decent amount that can lead to larger wins with maximum bets reaching up to 250.

Our Verdict

It's easy to see why Big Bass Bonanza continues to be a staple within the iGaming community as it has everything anyone could ever want. Of course, the features are simple but rewarding at times.

This paired with the charming design and overall impressive gameplay makes Big Bass Bonanza a classic slot that will remain popular for a long time.
