The slot’s relaxing riverside theme is brilliantly brought to life on the screen. The base game has a simple set up with an underwater background showing rocks and plant vegetation and rising bubbles, most probably produced by the fish. A catchy tune plays along; however, if you want a real fishing experience you can switch the theme music off and listen to the sounds of the birds chirping and the passing ripples of the water. In the free spins feature, the background remains but the background music becomes a lot more energetic as there are a few more bites to take advantage of, adding to the enjoyment of the gameplay.
The game’s symbols are very appropriate to the theme. There are five higher value theme related symbols including a float, fishing rod, dragonfly, fishing box and fish. The lower value symbols are represented by the royals, A, K, Q, J and 10. The scatter symbol found in the base game is a jumping fish that is trying to catch the bait. Wild symbols are only present in the free spins bonus feature and this is represented by a fisherman proudly showing off his catch of the day.
The main bonus feature of Big Bass Bonanza is free spins.
Free spins can be activated by three or more scatter symbols landing on the reels of the base game. The number of scatter symbols landed will determine the number of free spins given. Three scatter symbols will give you 10 free spins, four provides 15 free spins and five gives 20 free spins.
During the free spins, standard base game wins will continue to apply. However, the wild card fisherman becomes active. When the wild lands during a free spin it will collect all the fish money symbols that have landed on the reels. The fish will have random money values visible within their symbol and each value will be collected.
A re-trigger feature also applies to the free spin bonus to include a multiplier effect on winnings. When the wild symbol lands four times during the free spins you will be granted an extra 10 free spins and x2 multiplier. This is recurring for a second retrigger with 10 free spins and x3 multiplier and a third re-trigger of 10 free spins that offers a whopping 10x multiplier. There is no forth re-trigger available and the free spin bonus feature will automatically end if the winnings meet 2100x the bet.
One more additional feature to the free spin comes on the last spin. If you land a wild there is a chance that fish with money symbols may suddenly appear after the spin has ended to provide some final additional winnings.
