Big Bass Boom review

The Big Bass series of games developed by Pragmatic Play has already become legendary, and the company continues to develop it. At the end of 2024, the Big Bass Boom slot machine was launched, which I’d like to talk about today. It retains the basic mechanics and fishing theme, while also benefiting from some interesting modifications.

The game is characterized by high volatility and a 97.97% return to player (RTP), which largely explains its growing appeal to experienced players. You can expect big wins, even if they aren’t the most frequent. Attractive bonuses will allow you to win more often. The maximum payout reaches 5,000 bets! I’ll tell you more in my review.

Gameplay and symbols

The fishing theme of Big Bass Boom will seem familiar. The developer has released many similar slot machines, with only minor design tweaks. This time, you’ll head to a mountain lake to catch a real monster of a fish. During the game, you can watch bubbles rise from the bottom, as well as the lake’s inhabitants swimming in the background. The graphics are high-quality and packed with captivating visual effects. The mobile version is well-adapted and will impress you with the same graphical quality as the PC version.

Fans will be delighted: the winning mechanics remain unchanged and are comparable to the original. On the 5×3 grid, you’ll find 10 fixed paylines where you can land winning combinations of symbols. To win, you need to place 3 to 5 identical symbols on a payline.

Before each game and at the start of each new round, you can place a bet between $0.10 and $250. This wide range of bets will satisfy beginners, experienced players, and high rollers alike. Please note that payouts are only processed in one direction: from left to right.

The symbols also retain some characteristics from the original. In addition, the game board features fish with their values, as well as special Wild and Scatter symbols. I’ll tell you more about these features a little later.

Features and bonuses

If you’ve already played slots from this series, the Big Bass Boom slot machine and its bonuses will seem familiar. But let’s explore all its features.

Wild

The fisherman appears during free spins. This symbol appears on all reels. It can substitute for any other symbol, except the Scatter, to form more winning combinations.

Free tours

By collecting 3, 4, or 5 Scatter symbols on the board, you trigger a round of 10, 15, or 20 free spins, respectively. If, during the base game, you only collected 2 Scatter symbols on the board, you have a chance to activate a random feature and draw another Scatter symbol from the bottom to trigger the free spins.

Before the start of the bonus round, 0 to 5 modifiers will be selected:

  • More Fish – in the bonus game, there are more fish with names;
  • More Fishermen – There will be more fishermen in the free tours;
  • Dynamite – increase the chances of activating the dynamite function;
  • Hook – the hook works more often and catches bigger fish;
  • Bazooka – increase the activation frequency of the explosion function;
  • Start from level 2 – You start the bonus round with an increased multiplier and additional turns;
  • +2 Spins – You get 2 extra free spins.

By collecting fisherman symbols that act as Wilds, you’ll increase the bonus round level. There are 4 levels in total, and for each level, you need to collect 4 fishermen. With each new level, you get more free spins and the bonus multiplier increases from x2 to x10.

Fish Collector

In both the base and bonus games, you’ll see fish with values ​​on the game board. The value is random and ranges from 1x to 500x your total bet. The fisherman can only catch fish during free spins. For this to happen, both the fish and the fisherman must appear on the board simultaneously. You’ll receive the total value of all the fish you’ve caught.

Conclusion

Big Bass Boom is a game that will appeal to all fans of Pragmatic Play’s eponymous slot series. It features familiar mechanics, multi-level free spins, high stakes, and numerous random features. You can expect big wins and a great time. However, it’s important to note the high volatility. Activating the bonus round with large wins isn’t easy, and the frequency of winning combinations is quite low.
