Game rules

The names may be similar, but don’t be fooled! The Big Bass Bonanza game is a fishing-themed game, unlike the better-known Bonanza slot, which is all about mining. Land three or more Big Bass Scatters to trigger the bonus rounds, where the Wild fisherman appears to help you discover free spins and up to 10x multipliers to boost your prize payouts.

Big Bass Bonanza symbols

Most online slots games tend to use playing card icons to represent lower-value symbols, and Big Bass Bonanza is no exception. Higher-value icons take the form of fish symbols, each with a prize amount attached, although these don’t come into play until the bonus rounds. You’ll also spin up dragonflies, fishing tackle boxes, reels and floats. The fisherman is Wild, but he only appears during the bonus games, which are triggered by landing Big Bass Scatter symbols.

Min/Max wagers & lines

Payline costs start from just £0.01 each, with all 10 paylines fixed for every spin. You can play from 1 – 10 coins on each payline too, giving a wagering range from £0.10 to £250 per game. That means there’s something for every type of player, although the higher-than-average volatility suggests that low-stakes players should stick to playing Big Bass Bonanza free play games, at least in the first instance, while they get accustomed to gameplay.

Pay table & bonus rounds

Playing card symbols pay up to 10x your payline bet for landing five of a kind across a payline. But it’s the fishing-themed symbols that deliver the highest returns, so these are the icons you’ll be wanting to see lining up on the reels. Match up three or more of the fish symbols to win up to 20x your stake, with five tackle boxes, or five dragonflies on a payline paying 50x your bet. This increases to 100x your wager for matching fishing reels, with the biggest payouts reserved for the float symbol. This doesn’t just pay out up to 200x your payline stake for five of a kind, but it also starts paying out cash prizes for matching just two examples from left to right on the reels.

Big Bass Scatters award up to 20 free spins when you land three or more, anywhere on the reels. This is where the best prize-winning potential can be found, as the fisherman Wild is now added into the game. In addition to helping to form winning combinations, he also adds the value of any fish with monetary prizes attached, helping to boost your prize payout.

And there’s still more to discover! Wilds are collected throughout the bonus round, with 10 more free spins and a 2x multiplier awarded once you’ve achieved four. Collect four more to win 10 more spins and a 3x multiplier, increasing to 10 more spins and a 10x multiplier once you have 12 Wilds in total.

Animation, graphics, and soundtrack of Big Bass Bonanza

Big Bass Bonanza is a fun game with engaging graphics, but this isn’t a slot for people who want flashy animations. Despite the underwater theme there are no moving waves or swimming fish, which would have added some nice extra touches to gameplay. There’s an accompanying soundtrack to add some extra atmosphere, but this game is definitely more about the features than the artistry.

Big Bass Bonanza RTP and volatility

The Big Bass Bonanza slot RTP comes in at a pleasing 96.71%, which is comfortably above the average for an online slot and compares favourably with the Buffalo Blitz slot RTP which is 95.96%. This suggests that there are some big cash prizes on offer, but don’t rely on the Big Bass Bonanza RTP ratio alone as a factor for playing the game. This slot offers risky gameplay, with a volatility rating of 4/5, which puts it very much on the high side.

Unless you’re a high-risk slots fan we strongly recommend playing the Big Bass Bonanza demo to start with, before moving onto paid-for games in which you can wager your own cash. It won’t guarantee you a successful outcome, but at least you’ll have a good idea of how the game’s mechanics play out over time.

Mobile availability

Pragmatic Play are well aware that slots fans these days like to be able to access their favourite games on mobile devices. So you can play Big Bass Bonanza across any of your connected devices with no loss of game quality, whether you play on PC or on your smartphone or tablet.

Big Bass Bonanza verdict

Fishing fans won’t need any encouragement to try their luck at this slot. There are some good winning opportunities once you land the free spins bonus round, but you’ll need to make sure you have a bankroll robust enough to take you that far in the game. We recommend trying out the Big Bass Bonanza demo to get a feel for the game before risking your own cash, as the volatility can be cruel on your bankroll if it’s not particularly robust.
