How to play Big Bass Bonanza - Slot description

You trigger the free spins round when you get 3 to 5 scatters anywhere on the playing field, for which you get 10, 15 or 20 freespins respectively. So far, everything looks pretty standard, but there are a few factors here that both complicate the gameplay.

Firstly, the wild fisherman can only help you during the bonus round. He can appear on all the reels, and he will be part of any winning combination of regular symbols. "Fish symbols appearing on the game grid can have different values and you will win fish prizes when the wild fish is shown on the field on the same spin. If more than one fisherman comes to your rescue, the value of the 'fish' symbols is multiplied by the number of wild symbols that appear.

But that's not all! Each wild present on the playing field will be added to the counter above the reels, and each 4th wild on the grid activates additional freespins and increases the progressive multiplier. You can only do this three times, but you'll get 10 new Freespins each time. The multiplier increases to 2x for the first bonus restart, then to 3x and finally to 10x when you get a total of 12 wilds.


The game reels are located right at the bottom of a small lake, where the main character of the game came to fish. It is on them that symbols with a variety of images will rotate, from which players can create prize combinations and receive the appropriate multipliers bet. This whole gameplay will be accompanied by a built-in melody, sound effects and various animations from winning combinations.
