Theme, Audio & Symbols

Our Fisherman friend fronts the game as he does with all of the Big Bass games. In this title, he’s grabbed his fishing gear and is relaxing at the side of a lake somewhere bright and sunny. It has a happy ambience with uplifting music and sound effects.

As always, the grid is set under the water, where you see popping bubbles, swaying weeds and fish swishing past on your screen. The weather is gorgeous and you can see sunlight glinting just below the water’s surface. All-in-all it makes for a peaceful slot experience.

During the Hold & Spin feature - which I’ll tell you more about in the Bonus Features section - you flip into a dark nighttime scene. Here, the Fisherman is doing some after-hours fishing, reeling in his catch of the day (or should I say, night). Here you can see glowing fireflies zipping around the screen.

The reels' symbols are bright, which is a contrast against the tranquil shades of blue. The highest-value symbol is the fishing float, and below are all of the values of each symbol:

  • 10 & J symbols: 3 = 0.1, 4 = 0.2, 5 = 0.4 or 6 = 1 x bet
  • Q symbol: 3 = 0.1, 4= 0.2, 5 = 0.4 or 6 = 1 x bet
  • K & A symbols: 3 = 0.2, 4 = 0.4, 5 = 0.6 or 6 = 1.5 x bet
  • Fish symbol: 3 = 0.2, 4 = 0.4, 5 = 0.6 or 6 = 1.5 x bet
  • Tackle Box symbol: 3 = 0.3, 4 = 0.5, 5 = 0.8 or 6 = 2 x bet
  • Dragonfly symbol: 3 = 0.3, 4 = 0.5, 5 = 1 or 6 = 2.5 x bet
  • Fishing Rod symbol: 3 = 1, 4 = 2, 5 = 2.5 or 6 = 5 x bet
  • Fishing Float: 2 = 1,3 =  2, 4 = 10, 5 = 25 or 6 = 50 x bet
  • Fishing Net Wild symbol: Substitutes for all paying symbols.
  • Lamp Mystery symbol: All instances transform to a random paying symbol.
  • Big Bass Scatter symbol: 3+ symbols landing triggers the Free Spins feature.
  • Fisherman symbol: Appears during free spins + collects Fish Money symbols.
  • Coin Money: Appears during Hold & Spin feature.
  • Diamond Money: Appears during Hold & Spin feature.

Big Bass Hold & Spinner Megaways Mobile

Like most modern-day online slot games,  Big Bass Hold & Spinner Megaways plays well whether you play on an iOS or Android device. The game will adapt to whichever device you're using, meaning that you can be assured of a superb experience whether you're using a smartphone, tablet, or desktop.  

Bonus Features

Big Bass Hold & Spinner Megaways is stuffed with features, so let’s take a closer look at them:

Free Spins

Landing 3 or more Scatters on the reels, triggers the Free Spins bonus round. 6 Scatter Symbols = 25 free spins, 5 Scatter Symbols = 20 free spins, 4 Scatter Symbols = 15 free spins and 3 Scatter Symbols = 10 free spins. During the Free Spins round, each Fisherman Symbol collects the values from the Fish Money Symbols, which you’ll see in the bar next to the grid. These are collected at the end of each round. Every fourth Fisherman Symbol collected means extra wins, which includes 10 extra free spins and multipliers added to the Fish Money Symbol collection.

Tumble Feature

After each spin winning combos are paid and all winning symbols disappear, the remaining symbols fall to the bottom of the screen and empty positions are replaced with new symbols coming from above. Tumbling will continue until no more winning combos appear.

Fish Money Symbol

Fish Money symbols have multiplier values attached to them at every spin, these range between 2x and 5,000 x the bet. These values can be won during the Free Spins bonus round. 

Mystery Symbols

Mystery symbols can land randomly, in the base game and these transform into paying symbols. During the Free Spins feature, Mystery symbols can randomly appear after a spin that contains only Fisherman Wilds and no Fish Money symbols. These symbols will then transform into any other random symbols.

Hit & Spin Bonus

During the base game, Coin Money symbols can land on the main reels, excluding the topmost grid. When 3 or more of these symbols land, the Hold & Spin feature is activated.The triggering Coin Money symbols remain in place while all other symbols disappear.  The initial Coin Money symbols added to the prize pool. You are given 3 respins, and any new Coin Money symbols that land will reset the respins counter to 3. Each new Coin Money symbol that lands allows the Fisherman to collect all the prizes on the reels.

Keep your eyes peeled for the Diamond Money symbols, where prizes range from 50 to 2,000 x your bet. If your winnings during the feature are less than 20 times your total bet, you are awarded 3 more respins. This feature will finish once you run out of respins.

Buy Feature

If you’re a non-UK player, you have the option of 2 Buy features. Firstly, you can buy your way into the Free Spins feature for the cost of 100 x the bet. Or, secondly, you can buy your way into the Hold & Spin feature for 120 x bet.

Expert Verdict

Whether you’re a fan of Big Bass games or not, this series seems set to go on and on. These games do have some decent features but can be a bit ‘samey.’ However, this one has a lot to write home about. It’s stuffed with features, and I love a Megaways game - what's not to like with all those paylines? The bigger grid with the smaller topmost grid makes it even bigger and better to enjoy on the screen. 

Big Bass Hold and Spinner Megaways has the highest max win at 20,000 x out of all of the Big Bass games. And it’s at the higher end of the scale for RTP. The following games are the highest with 96:71%: Big Bass Bonanza, Bigger Bass Bonanza, Christmas Big Bass Bonanza, Big Bass Splash and Big Bass Christmas Bash. Big Bass Bonanza Megaways and Big Bass Hold and Spinner Megaways come in at 97.70%. If you’d like to compare Big Bass games we’ve written this popular Big Bass slot series guide.

I enjoyed this game immensely as it’s packed with features and there’s plenty to keep your interest. With a tumble feature, hold and win, free spins and multipliers it really does cater for lots of tastes. With a decent RTP and max win thrown into the mix it’s definitely up there as one of my favourite Big Bass games.
