Cast your line out for the chance to reel in a colossal catch up to 4,000x in Bigger Bass Bonanza. The much-loved angling adventure has returned with 12 paylines and 4x5 reels, which enables more fish to be collected during Free Spins and a better chance of activating this exciting bonus. Free Spins not only includes a 10x multiplier, but also a Dynamite Spin and new Hook feature that bring fish to the surface for the fisherman to catch.

There is another great addition to this epic underwater slot. When 5 fish symbols land on a payline they will pay out the sum of their cash values without the need of the fisherman to collect them.

So, if you’re ready to go fishing for wins then play Bigger Bass Bonanza now or try out another one of our online slots and games, including fintastic Grosvenor Originals and Megaways games.

Free Spins

3 or more scatters that land in the base game will start the free spins feature with 10 spins. Any additional scatter adds an extra 5 spins, to increase the chance of landing that big fish. Free spins start with the fisherman collecting any fish cash values in view and multiplies these values by x1. Every 4th fisherman that lands unlocks the next stage, increasing the multiplier value of the fisherman and awarding an extra 10 free spins to the player, once the current number of free spins have been exhausted. The upper stages of the free spins, increases the fisherman multiplying value by x2, x3 and finally x10. The aim of the game is to reach the top x10 level. At the top level, a 50x fish now becomes a 500x fish when collected by a fisherman. You can also activate the dynamite spin. When a fisherman lands without any fish in view to collect, he can throw a stick of dynamite to bring fish to the surface, which he then collects as normal. There is also a new hook feature similar to the dynamite spin, when a fisherman lands with no fish in view, on a random chance a hook is dropped below the screen to try and lift up fish that have escaped landing on the reels.
