Big Bass Bonanza by Pragmatic Play (developed with Reel Kingdom) is a simple fishing slot that became so popular it spawned a long series of sequels. The idea is easy to follow: fish symbols carry cash values, and in free spins a fisherman wild reels them in. In this Big Bass Bonanza slot review: the reel set-up, how the fisherman collects fish values, the RTP and how to try it in demo.
Reels, paylines and the fish money symbols
- 5 reels, 3 rows, 10 fixed paylines.
- Classic fishing symbols: tackle box, rod, dragonfly, float and the big bass itself, plus card ranks for the low wins.
- Fish money symbols that show a cash value based on your stake.
- A scatter that triggers free spins.
In the base game, fish money symbols simply pay as regular symbols on a line. They only show their full value in the bonus.
Big Bass Bonanza free spins
Three, four or five scatters award 10, 15 or 20 free spins. During free spins, the fisherman appears as a wild. Every time a fisherman lands, he collects the cash value of every fish money symbol on the screen at the same time. One fisherman and a screen full of fish is the result everyone hopes for.
Retriggers and multipliers
Each fisherman you land is counted. Every fourth fisherman retriggers the feature with 10 more free spins and raises the multiplier applied to fish collections. According to the provider, the multiplier steps up to 2x, then 3x, and finally 10x. Reaching the later levels is rare but changes the round completely.
Big Bass Bonanza RTP and volatility
According to Pragmatic Play, the standard RTP is around 96.7%, with high volatility. As with all Pragmatic games, a casino may run a lower setting; check the info screen in the game.
Demo and free play
The Big Bass Bonanza demo is a good way to see how rarely free spins arrive and how much a round depends on fishermen and fish landing together. Many free spins rounds end with modest wins. Demo mode needs no deposit and is available at most casinos.

Big Bass Bonanza at BetKing, Bet9ja and other Nigerian sites
Pragmatic Play is one of the most widely carried studios in Nigeria, so Big Bass Bonanza is in the lobby of most operators in the table below; search for it after logging in to confirm. BetKing, Bet9ja and SportyBet hold national licences and run their slots in the same app and naira wallet as the sportsbook. MSport and Betway are licensed in Lagos State, and 1xBet is licensed there through Beaufortbet Nigeria Limited.
On free spins: Betway's welcome package has included a small number of casino free spins alongside its sports match (100% first deposit match up to N250,000 in free bets + 10 free spins + 10 Aviator free flights), but those spins are tied to a first deposit and to whichever games the promotion names, so they are not a no deposit offer on this slot. Check the promotion page before assuming any spins can be used on Big Bass Bonanza.
