A Pragmatic Play fishing slot with 5 reels, free spins that trigger on scattered symbols, and a 96.71% RTP. Wins come less often but can be much bigger.

Fish-themed 5-reel grid. Bigger Bass Bonanza is a fishing-themed slot on a 5-reel, 4-row grid where you form wins by landing matching symbols across 12 paylines from left to right. Released in 2021, the game combines base-game spins with a free spins bonus where a fisherman wild collects cash values scattered on the reels. High volatility means wins come less often and can be much bigger when they land.
Who enjoys this game. This slot suits players who can handle longer stretches between wins and prefer the chance of larger payouts. The minimum bet starts at £0.12 and rises to £5, so you can choose stakes that fit your session plan. If you prefer frequent small wins or want to avoid waiting for bonuses to trigger, a lower-volatility slot would feel more comfortable.
Free spins and cash collection. Free spins shape the round most. Land 3, 4 or 5 scatters to start 10, 15 or 20 spins where the fisherman wild only appears. When it lands, it collects every cash value on screen and adds it to your win. Every fourth wild collected retriggles the round with a multiplier that makes those cash values worth twice, three times, or ten times as much, up to three retriggers. The entire bonus is capped at 4000 times your stake.

How does the fisherman collect cash? Three, four or five scatters trigger ten, fifteen or twenty free spins. The fisherman wild appears only here, substitutes all symbols except scatters, and collects money values from all money symbols on screen when it lands. Every fourth collected wild retriggers ten more spins with a multiplier—multiplying collected cash by two, three or ten—up to three times. The round win caps at four thousand times your bet.
Start your session in the base game. The base game runs on a five-by-four grid with twelve fixed paylines, reading left to right on adjacent reels starting from the leftmost reel. Money-valued fish and regular symbols pay according to the paytable. Three matching symbols is the minimum needed to form most wins; the boat symbol pays from two matches.
RTP is the average return you can expect over a huge number of spins. The 96.71% figure shown here applies to the standard game. On any single session, you might see very different results.
You'll know whether to try the demo or go straight to real money play.
You can bet between £0.12 and £5 per spin on Bigger Bass Bonanza at Xtraspin Casino. Your maximum possible win at the highest bet of £5 is £20,000.
Automatic spins are not available for this slot on UK casino sites. You choose when each spin happens, keeping full control of your session throughout.
Bigger Bass Bonanza bonus timing. The Free Spins round triggers when three or more scatters land, but you won't know when that happens. No player can forecast the bonus or plan a session around it arriving at a set time.
Your session is yours alone. Your next spin might return half your stake or triple it. The RTP of 96.71 percent describes long-term results across thousands of sessions, not what your balance will do today.
Maximum win as realistic marker. The maximum win of £20,000 at the highest bet is a ceiling reached in extremely rare circumstances. Most sessions end far below it, and many end with a loss.
These slots vary in RTP between 96.50% and 96.52%, with four capping wins at 4000x bet and one reaching 25000x.
You'll know what bets work, why the RTP matters, how volatile the game runs, when bonuses trigger, what the maximum win is, and how this slot differs from others in its series.
Your budget comes first. Decide how much you can afford to spend before you open the game. Once that limit is reached, your session ends, regardless of whether you're ahead or behind.
Decide when to leave. Agree with yourself on a stopping point before you begin. A win can feel like reason to carry on, but it's the moment to step back and check whether you want to keep playing.
Can limits really help? Use your account's deposit and loss limits to control how much money is available for play. These tools work automatically and can't be overridden mid-session.
Your right to pause or step back. If the game stops feeling like entertainment, take a break. You can use session time reminders, reality checks or self-exclusion through your account or organisations like GamCare and GAMSTOP.
