Reel Kingdom / Pragmatic Play · 2021Bigger Bass Bonanza — what every player should know
Overview
Bigger Bass Bonanza is Pragmatic Play's fishing adventure on a 5×4 grid with 10 fixed paylines. Land three or more scatter symbols to unlock free spins where multipliers stack and chase that 4,000x ceiling.
How it plays
Bet between £0.10 and £250. The scatter pays mechanic means matching symbols anywhere on the grid count — you don't need traditional payline alignment. High volatility means long dry spells between wins, but the payout potential justifies the wait for bonus hunters.
The bonus round
Three scatters trigger free spins. During the bonus, multipliers accumulate on each win, building towards bigger payouts. This is where the 4,000x max win lives — one strong free-spin sequence can make the whole session. Land more scatters mid-bonus to extend your run.
Who it's for
High-volatility hunters with a £20+ session bankroll who can sit through 100+ spins dry for one bonus that pays the session. Suits anglers who love theme-play and don't mind chasing.
Avoid if
You chase small wins or play short 20-spin sessions. Bigger Bass Bonanza will exhaust your bank before the first bonus arrives.

Frequently asked questions
What's the RTP and how does it compare?
95.67% RTP sits mid-range for high-volatility slots. You'll lose 4–5p per £1 wagered long-term, but bonus wins can offset months of play.
Can I hit 4,000x without landing free spins?
No. The 4,000x max win requires the multiplier stack in the free-spin round. Base-game wins top out much lower.
