Big Bass Bonanza, a popular slot game in best online casinos in Ireland, was launched by Pragmatic Play partner Reel Kingdom in late 2020. While this online slot didn't bring many innovations compared to similar slots like Fishin' Frenzy, it did feature a more elaborate bonus game with the possibility of high multipliers up to x10 on scatter wins.

Its maximum success fell short of expectations, disappointing some players. The game attracted enough attention to inspire a sequel, Bigger Bass Bonanza, retaining the core gameplay while adding a few improvements.

Big Bass Bonanza Slot Pragmatic Play Features Symbols


The Big Bass Bonanza slot features a straightforward and cartoonish aesthetic centered on fishing.

The simplistic style of the visuals suits the "back to nature" theme, complemented by a lively backing track. The blue reels against an aquatic background showcase brightly colored royals from A to 10 and higher-value symbols related to fishing, including fish, a tackle box, a dragonfly, and a fishing rod.

The most valuable symbol is the kaleidoscopic float, offering a win of 200 times your total bet for 5 on a payline. The fisherman serves as the wild symbol, appearing only during the bonus round to substitute for any symbol except the scatter.

How To Play

Playing is possible by following these 3 steps:

  1. When you hit the +/- buttons, panel pops up where you adjust the number of coins wagered each line as well as the amount of each coin that contributes to the total bet. Alternatively, you can just increase the total value of your wager.

  2. The instant you hit the ''Spin'' button, the reels begin their movement.

  3. When ''Autoplay'' is on, a panel appears from which you may select between Turbo Spin or Quick Spin, as well as the number of automated spins.

Place your wagers and see if you can reel in the largest fish you ever imagined was attainable.


  • If you see a fisherman, you can consider him a wild card. Only present during free games, it is a substitute for any other icon aside from the scatter.

  • Free games are triggered by seeing at least 3 of the fish on a hook scatter symbol.

  • The value of money is represented by a green fish symbol.

  • Make a fish pile as a representation of wealth. The Money symbol's value is determined at random and can be used to win in both the main game and the Free Spins bonus.

About Pragmatic Play

Pragmatic Play is the most prominent software providers in the iGaming industry, supplying popular games to top operators.

Their extensive gaming options are available in major regulated markets, supporting multiple languages and currencies through a single API. With a dedicated team committed to creating beloved games and delivering exceptional services to partners worldwide, Pragmatic Play maintains a strong reputation.

Big Bass Bonanza offers straightforward features, with free spins as the sole bonus feature. However, these free spins include associated bonuses that add value to triggering this feature.

RTP & Volatility

The RTP (Return to Player) for a game is determined by the casino.

It's important to note that playing the same game at different casinos can result in varying RTPs, even within the same casino. The difference in RTPs among casinos can be significant, ranging from the highest at 96.71% (e.g., All British Casino) to the lowest at around 90.5%, representing a 6% difference.

While this discrepancy may not have a noticeable impact on short play sessions, choosing a casino with a lower RTP means you're getting less value over time. This is a consideration that applies to many games.


Online casino bonuses play a vital role in slots.

While the wild symbol is present in the game, it appears only during bonus rounds, not regular gameplay. To activate the free spins bonus round, you need to land at least 3 scatter symbols, depicting the fish trying to return to water. Landing more scatter symbols awards a larger number of free spins, up to a maximum of 20 for 5 scatter symbols.

During the bonus round, you may encounter miniature greenfish with monetary values, which the wild fisherman collects to enhance your winnings. Multiple wilds in a round can result in a multiplier effect. Additionally, the fisherman awards credits in a meter above the reels with each appearance. After the 4 appearance, the feature retriggers, granting additional spins and a multiplier.

To achieve the maximum multiplier of x10, you need 10 wild symbols on the reels.

The maximum number of free spins you can accumulate is 50. During the free spins round, the top reward is x2100, which ends the free spins regardless of remaining rounds. However, the substantial reward compensates for the lack of additional spins.

Free spins activate with 3 or more scatter symbols, granting 10, 15, or 20 spins based on the triggering scatters. In this round, each wild collects values from money symbols on the screen. Every 4th wild collected retriggers the feature, adding 10 spins and increasing the money symbol multiplier from x2 to x3, then x10. After 3 retriggers, the feature no longer retriggers.

Additionally, Fish Money symbols may appear randomly when only one wild remains on the screen at the round's end.


Big Bass Bonanza is a relatively straightforward slot machine, as it only features 10 pay lines for the entirety of the main game plus the bonus round. Even though you only need 2 of a kind of higher premium symbols to win, you will typically require three in a row in order to do so, as this is the industry standard. Although full lines appear to be uncommon, they are typically more likely with the fish itself and pay exceptionally well.

Big Bass Bonanza is a straightforward slot machine with 10 paylines throughout the main game and bonus round. While 2 of a kind of premium symbols can win, 3 in a row are typically needed, aligning with industry standards. Full lines are rare but more likely with the fish symbol, offering high payouts.

Highest payout

There is a theoretical maximum multiplier of 2100x, however, this has been hit several times in practice, making it less "theoretical" than other slots with much larger multipliers. Payouts can be as much as 2,100 times your initial wager on a single spin. This will occur during the bonus rounds where a multiplier of up to 10 times will be in play. If the 2100x multiplier is reached during the free spins bonus, the game ends immediately.

Maximum bet

The most you can win while playing Big Bass Bonanza is 2100 times your total wager. When playing at the highest level possible, the highest possible total winnings are €525,000.

Minimum bet

The least wager that can be placed is €10.

IrishLuck's Expert Verdict

While Big Bass Bonanza may not boast any standout features, it incorporates numerous elements into its framework.

The visuals are adequate but not captivating, with familiar components for genre veterans. Nonetheless, it offers an enjoyable experience that entices players to return for more, especially in pursuit of free spins. Perhaps a significant win might even inspire you to try fishing after playing this game!
