RTP and Volatility

The default RTP is 96.71%, which is above average for online slots. Pragmatic Play offers operators the option to set lower RTP versions (96.07%, 95.51%, 94.49%), so the actual RTP at your casino may differ. Check the game’s info screen (the “i” button) to confirm which version you are playing.

Volatility is rated medium by Pragmatic Play. In practice, this means you will see regular small-to-medium wins from the base game paylines and occasional larger hits from the money collect mechanic. The free spins round is where the biggest payouts occur, but even these tend to be in the 50-500x range rather than massive 1,000x+ hits.

Hit Rate and Win Frequency

Big Bass Bonanza has a hit rate of approximately 1 in 3.3 spins, meaning roughly 30% of spins produce some kind of win. Most of these are small payline wins from card symbols that return less than your stake.

The money collect feature triggers roughly once every 40-60 spins in the base game. Free spins trigger approximately once every 100-120 spins on average. This is where the game’s biggest wins happen, because fishermen can now land on four reels instead of one.

Free Spins and Bonus Features

Money Collect (Base Game)

Fish symbols land on reels 1-4 carrying random cash values. If the fisherman wild lands on reel 5 during the same spin, he collects all visible fish values. The fisherman also acts as a wild, substituting for regular symbols to complete paylines.

Free Spins

Landing 3 scatter symbols (the tackle box) triggers 10 free spins. Landing 4 scatters awards 15 spins, and 5 scatters gives you the maximum 20 free spins. During the feature, the fisherman can appear on reels 2, 3, 4, and 5 instead of just reel 5. Each fisherman collects all visible fish values. If multiple fishermen land in one spin, each collects independently. Fish symbols in the bonus round can carry values up to 2,000x your bet – far higher than in the base game.

Retrigger Multipliers

During free spins, collecting 4 fisherman wilds triggers a retrigger with an increasing win multiplier. The first retrigger applies a 2x multiplier to all subsequent collections, the second increases it to 3x, and the third pushes it to 10x. This escalating multiplier system is where the game’s biggest wins come from – a 10x multiplied collection of high-value fish can approach the 2,100x cap in a single spin.

Gamble Feature

After any win, you can choose to gamble your winnings on a card colour (2x) or suit (4x) prediction. This is entirely optional and carries the obvious risk of losing your win.

• Set a session budget before you start. With a bet range of €0.10 to €250, it is easy to scale up after a dry spell. Decide your total session spend and stick to it.
• The base game fisherman is reel 5 only. Most spins where fish symbols appear will not result in a collection. Do not chase – this is normal for the game.
• Free spins are where it pays. The free spins round puts fishermen on reels 2 through 5 with escalating multipliers up to 10x.
• Check the RTP version at your casino. Pragmatic Play offers four RTP settings (96.71%, 96.07%, 95.51%, 94.49%). The “i” button in the game shows which version you are playing.
• Use autoplay stop conditions. Set a loss limit and a single win limit to stay in control during longer sessions.
• The gamble feature is high risk. The odds are fair but you lose everything if you guess wrong. Most experienced players skip it or only use it on small wins.
