Pragmatic Play via Reel Kingdom | 96.50% RTP | Tested on 16 game screens
This championship-level slot delivers maximum volatility with four lightning bolts. Payouts arrive less frequently but pack heavyweight potential, perfect for players hunting that knockout 5,000x total bet prize during Free Spins rounds.
Every colourful fish carries random cash values from 2x up to 5,000x your total bet. When Wild boxer symbols land during Free Spins, they collect all visible fish money instantly.
Land three, four or five Scatter fish badges to win 15, 20 or 25 free spins. Special reels activate with both blue and red boxer Wilds appearing to collect money symbols.
Blue and red Wilds fill separate collection meters. Every 4th Wild collected retriggers the feature with 10 additional spins and boosts that Wild's collection multiplier to 2x, then 3x, finally 10x at maximum level.
When fish symbols land without Wilds at the end of a free spin, a fishing hook may randomly pull an entire reel upward to drag Wild boxer symbols onto the visible grid to collect those money values.
If Wilds appear but no fish symbols are visible, a Knock Out animation may randomly trigger to replace all non-Wild symbols with fresh symbols, giving another chance to land money fish on that spin.
During Free Spins when Wilds land but no fish appear, the camera spin feature can randomly place additional fish money symbols in empty positions to guarantee collection opportunities.
Big Bass Boxing Bonus Round maintains a consistent 96.50% theoretical RTP across all play modes—standard base game, Ante Bet multiplier, Buy Free Spins (100x bet), and Buy Super Free Spins (300x bet). This unified return rate applies whether you naturally trigger features or purchase them directly.
Skip the base game and instantly trigger Free Spins with guaranteed Scatter symbols landing on the triggering spin.
Enter the premium Free Spins round with dramatically easier retrigger conditions for extended money collection.
Use the plus and minus buttons to select your total bet between $0.10 and $375.00. The left panel displays your current bet and the optional Higher Chance toggle for 15x Ante Bet mode, which increases Scatter frequency.
Press the large circular spin button with the gorilla crown logo to play normally, or click the magenta Buy Free Spins or amber Buy Super Free Spins buttons on the left to purchase immediate bonus entry.
Wins form when three or more matching symbols land on adjacent reels from left to right across any of the 10 active paylines. Premium boxing equipment symbols pay substantially more than card letters and numbers.
Land three, four or five Scatter fish badges anywhere on the reels to win 15, 20 or 25 free spins. Two Scatters may trigger a respin or hook feature to pull in the third Scatter needed.
During Free Spins, blue and red boxer Wilds collect all money values from fish symbols visible on screen. Wilds accumulate in colour-coded meters—every fourth Wild retriggers spins and increases that colour's collection multiplier.
Big Bass Boxing Bonus Round caps total wins at 5,000 times your stake. If your accumulated win during a Free Spins round reaches this maximum, the feature immediately concludes, awards the capped prize, and forfeits all remaining spins. This applies to both natural triggers and purchased bonus rounds.
Before each spin, you can toggle between two bet multiplier modes. The standard 10x multiplier provides normal base game behaviour with regular Scatter frequency. Switching to 15x multiplier increases your total bet by 50% but significantly boosts the likelihood of naturally triggering Free Spins by adding more Scatter symbols to the reels. Note that Buy Feature buttons become disabled when Ante Bet is active.
Wild Collection Meter Mechanics: Blue and red boxer Wilds that land during Free Spins are tracked separately. When either metre reaches four Wilds, the feature retriggers with 10 additional spins and that Wild type gains a 2x money collection multiplier. Reaching eight Wilds upgrades to 3x, and twelve Wilds unlocks the maximum 10x multiplier. After sixteen Wilds in a single metre, no further retriggers occur from that colour.
Three random features can activate during Free Spins to optimise money collection. The Hook feature pulls an entire reel upward when fish symbols appear without Wilds, potentially revealing hidden Wild symbols above. The Knock Out feature transforms all non-Wild symbols when Wilds land without fish. The Camera Spin places additional fish money symbols in empty positions when Wilds are present but fish are scarce.
All paylines pay left to right on adjacent reels starting from the leftmost position. When multiple winning combinations occur on different paylines in a single spin, all wins accumulate into your total payout. Only the highest win on each individual payline is paid.
