Cast your line into 147,456 ways to win with cascading tumbles, Hold & Spin respins with guaranteed 20x minimum wins, and unlimited Free Spins retriggers with climbing multipliers up to x10 and beyond.
This isn't just another fishing slot. Reel Kingdom and Pragmatic Play have engineered a genuine hybrid mechanic that layers Big Time Gaming's Megaways engine with dual bonus modes, cascading tumbles, and a Fisherman collection system that rewards patience with explosive multipliers.
Each spin delivers 2 to 6 symbols per reel across 6 vertical reels, plus 3 independent horizontal top rows that lock and unlock randomly. The result? Up to 147,456 ways to win that recalculate every single spin.
Variable paylines every spinLand 3+ Coin Money symbols to trigger respins. Each new coin resets your 3 respins. Diamond Money symbols can hit with values up to 2,000x. Guaranteed minimum 20x win—if you don't hit it, you get 3 more respins automatically.
Minimum 20x guaranteed3 to 6 Scatters award 10 to 25 free spins. Fisherman symbols collect all Fish Money values on screen. Every 4th Fisherman retriggers +10 spins with a multiplier: x2, x3, x10, then +x10 each retrigger with no limit.
Unlimited retriggersAfter every spin, winning symbol combinations explode off the grid. Remaining symbols cascade down, and new ones tumble from above to fill the gaps. This continues until no new wins form. The reel heights stay locked from the initial spin—so if reel 3 had 6 symbols at the start, it keeps 6 throughout all tumbles in that sequence. This creates chain reaction potential where a single $2 spin can trigger 5, 8, even 12 consecutive tumbles.
Above reels 2, 3, 4, and 5 sit three horizontal rows that spin independently from right to left. The topmost row contains only Wild symbols or blanks. The two rows beneath can show any paying symbol. Each row randomly locks (red indicator) or unlocks (green indicator) before every spin. Only unlocked positions count toward Megaways and winning combinations. When all three unlock with Wilds, you're looking at 6+ symbol reels with Wild substitutions across the center—this is where 1,000x+ base game hits happen.
The moment 3 or more Coin Money symbols land anywhere on reels 1-6 (they don't appear in the top rows), the Hold & Spin feature activates. Here's the exact sequence:
This minimum guarantee is critical. It means even a "dead" Hold & Spin round where only your 3 trigger coins stick will loop until you hit at least 20x. In testing, the average Hold & Spin pays between 40x and 120x, but filling the grid with high-value coins can push wins beyond 1,000x. You can also buy direct access to this feature for 120x your bet.
Landing 3, 4, 5, or 6 Scatter symbols awards 10, 15, 20, or 25 free spins respectively. During this mode, Fish Money symbols appear on all reels (except the top row). These display values from 2x to 5,000x. Fisherman symbols also land on any reel. When a Fisherman hits, he instantly collects every Fish Money value visible on that spin. Both the Fisherman and Fish Money symbols then disappear, triggering a tumble.
The game tracks your Fisherman count. Every 4th Fisherman collected retriggers the feature with +10 spins and activates a multiplier for all future Fish Money collections:
Retriggered spins play after the current batch ends, and the multiplier applies only to those retriggered spins—not retroactively. This structure incentivizes long Free Spins sessions. A single 5,000x Fish Money value collected at x10 multiplier delivers 50,000x (capped at the 20,000x max win rule). Occasionally, if only Fishermen land with zero Fish Money symbols visible, a dynamite animation can randomly spawn Fish Money positions before the tumble resolves.
Mystery symbols (silver glowing orbs) can appear randomly in the base game. When they do, all instances on screen transform into the same matching paying symbol before wins evaluate. During Free Spins, if a spin lands only Fishermen and no Fish Money, Mystery symbols may trigger and convert into other symbols to create paying combinations.
Two instant-buy options bypass base game grinding:
At max bet ($250), buying Free Spins costs $25,000 CAD. At minimum bet ($0.20), it's $20. The Buy Feature maintains the same RTP as organic triggers, making it a time-saver rather than a value play.
The instant your total win in a single round (base spin + all tumbles, or bonus round total) reaches 20,000x your bet, the round immediately ends. You're paid the 20,000x cap, and any remaining free spins, respins, or tumbles forfeit. On a $2 bet, that's a $40,000 CAD payout. This cap applies identically across base game, Free Spins, and Hold & Spin modes.
Big Bass Hold & Spinner Megaways is classified as high volatility (5/5). This means extended losing streaks are mathematically expected, balanced by the potential for large wins in short bursts. The 96.70% RTP is a long-term theoretical return—short sessions can deviate significantly. Set deposit limits, take breaks, and never chase losses.
