Base Game & Features

Big Tuna Bonanza is the latest medium volatility release from BGaming, consisting of 5 reels, 4 rows, and 10 fixed pay lines. Winning combinations are guaranteed when 3 or more of the same symbols land on reels 1-5, starting from the leftmost reel.

The highest-paying symbol falls to the Tacklebox, followed by rods, bait, nets, and 5 coloured shells. Each paytable symbol awards a fixed payout between 0.2x and 50x your bet, where applicable.

In addition, the Fisherman acts as a Wild & Collect symbol, substituting for all symbols except Scatter and Prize symbols. Fisherman Wilds are only available during the Free Spins mode, and appear on all reels during this time.

Prize Symbols

During gameplay, special Fish symbols reveal random Cash Prizes between 1.5x and 10x your bet. In the base game, Fish symbols can appear on any of the reels. When 3 or more Fish Prizes connect on an active pay line, the sum of their values is applied to the total win.

Double Chance & Bonus Buy

Players within permissible regions can utilise the Bonus Buy option, which guarantees to trigger the Free Spins mode for 100x their bet.

Alternatively, UK players and other countries can activate the Double Chance Feature for an additional 50% of their current bet per spin. With this feature active, the chances of triggering the Free Spins mode are doubled.

The Bonus Buy and Double Chance features have a theoretical RTP of 97.20%.

Big Tuna Bonanza has a fixed max win potential of 5,000x your bet. If a game round exceeds this figure, the current mode ends, and the player returns to the base game with the qualifying amount.

Big Tuna Bonanza Free Spins

Big Tuna Bonanza has a Free Spins mode available, which triggers when 3, 4, or 5 Scatters appear in a base game spin, awarding 10, 15, and 20 Free Spins, respectively.

In this round, Prize symbols appear on reels 2-5 and pay only when a Fisherman Wild falls within the same spin. Each Fisherman Wild will gather all available Cash Prizes, awarding the total amount for that spin.

Above the main reel set is a special Fisherman Trail, split into 3 sections. For every 4th Fisherman Wild collected, the Free Spins mode retriggers, awarding the following outcomes:

  • Level 1: Awards 10 Free Spins and a x2 Multiplier
  • Level 2: Awards 10 Free Spins and a x3 Multiplier
  • Level 3: Awards 10 Free Spins and a x10 Multiplier

Please note that each active Multiplier is applied to the Fisherman Wild and all Cash Prizes it collects throughout spins.

Our Honest Verdict

When we catch wind of a new Fishing slot release, we’re hopeful that it will not follow the same path as others in its category, and by that we mean follow in the footsteps of Reel Kingdom’s extensive Big Bass Bonanza series.

When the first 1 or 2 Big Bass Bonanza slots came to light, the idea of the Fisherman Wild collecting Cash Prizes was still very much in its infancy. Still, as the years have advanced, a large number of software developers have incorporated this as part of their own releases, leading to an overwhelming number of fishing games with the same mechanics.

There are, however, a few fishing games that stand out for their unique features and mechanics, including Push Gaming’s Fish ‘n’ Nudge sequel and 4ThePlayer’s 4 Fantastic Fish series, but it’s not too often that we can say this.

Whether it’s considered good or bad, Big Tuna Bonanza falls into the overwhelming category of fishing slots like Big Bass Bonanza, utilising a Fisherman Collect feature, Fish Prizes, and the traditional Fisherman Trail during free spins.

Players with a fondness for this particular style of gameplay will find Big Tuna Bonanza a breath of fresh air thematically. The game opens up to crystal clear waters, vibrant colours, fun animations, and high-quality graphics.

In the base game, Fish Prizes are limited to the Free Spins mode, but they can create a winning combination when 3 or more appear on an active pay line. Besides this, there isn’t much biting in the base game, except for the anticipation of Free Spins.

For UK players, they can boost their chances of triggering the Free Spins mode by utilising the Double Chance feature; however, those within permissible regions can dive straight into the action for 100x their bet via the Bonus Buy tab.

It’s during the Free Spins mode that Fisherman Wilds, Multipliers, and the Fisherman Trail become available, awarding many opportunities to claim the 5,000x max win potential.

All in all, Big Tuna Bonanza is a great addition to the fishing category, offering iconic features and mechanics, light-hearted gameplay, and up to 5,000x in max win potential.
