Shark Boss — Feeding Frenzy Multipliers
A boss shark patrols a 5×3 grid with ten paylines. Shark Attack Feature triggers randomly mid-spin, transforming low symbols into high-tier ones. Jaws Wilds substitute everything except scatters. Deep Dive Free Spins is the bonus round, where Feeding Frenzy Multipliers compound across consecutive wins toward the deeper reach.

Shark Attack, Jaws Wilds & Feeding Frenzy
Shark Boss runs on a 5×3 grid with 10 fixed paylines. Below the surface a boss shark patrols the reels, and at any point during base play the Shark Attack Feature can fire — the predator charges across the grid, devours three to eight low-pay symbols, and replaces them with Jaws Wilds. That random conversion is the engine that turns lifeless spins into multi-line wins, and it stacks naturally with the high-volatility math model Play'n GO has tuned to 96.20% RTP.
Three Scatter symbols open Deep Dive Free Spins — ten spins that descend through five depth levels. Each level adds 1x to the global multiplier (depth 1 starts neutral, depth 5 hits 5x), and Shark Attack frequency climbs the deeper you go. Jaws Wilds substitute for every paying symbol except scatters and inherit the active depth multiplier, so two wilds aligned at depth 5 already deliver 5x on that line's payout. Two or more scatters during the round retrigger the dive.
At maximum depth the Feeding Frenzy Multiplier can trigger: the shark goes berserk across all reels, eating most low-tier symbols at once and flooding the grid with wilds and premiums. That is the route to the 5,000x cap. Players who want to skip the wait can use Bonus Buy where it is permitted, paying around 100x stake to enter Deep Dive directly at the same RTP.

Bonus Mechanics Explained
5 mechanics drive the 5,000x max win. Here's exactly how each one works.
Shark Attack Feature
How to Trigger
Random base-game modifier. Can fire on any spin without warning, slightly more often on dead grids where three to eight low-tier symbols are clustered.
What Happens
The boss shark sweeps across the reels and eats between three and eight low-pay symbols, replacing them with Jaws Wilds. The wilds then resolve as part of the spin payout, often turning a no-win grid into multiple connecting lines. The number of symbols converted is RNG-driven, not tied to the bet size.
Multipliers
No multiplier on the feature itself in base play — value comes from the freshly placed wilds substituting on payable lines. Average post-Attack payout sits around 6x-10x stake.
Odds
Roughly one Shark Attack per 30-40 base spins. Trigger rate climbs sharply during Deep Dive Free Spins, especially at depth 4 and 5.
Variants
During Deep Dive the converted Jaws Wilds inherit the active depth multiplier, so the same Attack at depth 5 pays five times as much as the same Attack in base.
Strategy
Treat Shark Attack as the primary base-game source of variance. Bankrolling for 200-300 spins between meaningful Attacks keeps sessions sustainable; chasing them with bigger bets after a long dry stretch is gambler fallacy at high volatility.
| Type | Random base modifier |
| Symbols Eaten | 3-8 low-tier |
| Converts To | Jaws Wilds |
| Base Rate | ~1 per 30-40 spins |
| Boost in FS | Yes, scales with depth |
Deep Dive Free Spins
How to Trigger
Land three Scatter symbols anywhere on reels 1, 3 and 5. Two scatters on a base spin land an empty teaser.
What Happens
Awards 10 free spins that descend through five depth levels. Spin one starts at depth 1 (neutral), and each progress trigger pushes the dive one level deeper. The depth level acts as the global multiplier on every line win and on any wild placed by Shark Attack. Two or more scatters during the round retrigger the dive and reset the depth pace.
Multipliers
Depth 1 = 1x, Depth 2 = 2x, Depth 3 = 3x, Depth 4 = 4x, Depth 5 = 5x. Multipliers apply to base line payouts AND to any active Jaws Wild on that line.
Odds
Natural trigger: roughly 1 in 200 base spins. Retrigger probability inside the round: ~15%. Reaching depth 5 within a single round: ~25% of free-spin entries.
Variants
Bonus Buy entry skips the trigger wait but starts you at depth 1 like a natural drop — the dive still has to be earned.
Strategy
Don't bail out by closing the tab during early depths — most of the value lives at depth 4 and 5 where Feeding Frenzy can fire. Track your remaining spins; if you stall at depth 2 with three spins left, the round's value is mostly already capped.
| Trigger | 3 Scatters reels 1/3/5 |
| Spins | 10 + retriggers |
| Depth Levels | 5 (1x → 5x) |
| Retrigger | ~15% per round |
| Path to 5,000x | Depth 5 + Feeding Frenzy |
Jaws Wilds
How to Trigger
Appear naturally on the reels in base play and Free Spins, plus every symbol converted by a Shark Attack becomes a Jaws Wild.
What Happens
Shark-shaped wild symbols substitute for everything except the Scatter. In base play they pay as themselves on five-of-a-kind. During Deep Dive Free Spins each Jaws Wild inherits the current depth multiplier — depth 3 wild = 3x on that line's payout, and two such wilds on one line stack multiplicatively to 9x.
Multipliers
Base: standard substitution, no extra multi. Free Spins: x1 to x5 inherited from depth. Two wilds on the same line at depth 5 = up to 25x on that payline before symbol values.
Odds
Natural Jaws Wild appearance: ~1 in 8 spins. Wild placement via Shark Attack inflates the effective rate substantially during the dive.
Variants
Inside Feeding Frenzy almost the entire grid converts to wilds, which is how the 5,000x line of payouts becomes mathematically reachable.
Strategy
In free spins, the value of a Jaws Wild scales with depth — landing wild-heavy boards at depth 1 is far less impactful than the same board at depth 5. Patience inside the dive is the play, not aggression.
| Substitutes | All symbols except Scatter |
| Base Rate | ~1 per 8 spins |
| FS Multiplier | Inherits depth (1x-5x) |
| Two-Wild Line Max | Up to 25x |
| Frenzy Coverage | Near full grid |
Feeding Frenzy Multiplier
How to Trigger
Random event during Deep Dive Free Spins, only available once depth 4 or 5 is active. Cannot trigger in base play.
What Happens
The shark goes into a feeding frenzy and devours nearly every low-tier symbol on the grid in a single sequence, leaving a board dominated by Jaws Wilds and high-pay symbols. Because the wilds inherit the active depth multiplier, the resulting payout compounds heavily — this is the mechanic that produces the headline 5,000x figure.
Multipliers
Single-spin payout from a Frenzy at depth 5 commonly lands in the 500x-2,000x range; the rare full-coverage outcome with all premium connections approaches the 5,000x cap.
Odds
Around 8% chance per spin at depth 4, climbing to ~15% per spin at depth 5. Probability of a Frenzy in any given Deep Dive entry: ~20%.
Variants
Some operator builds expose the depth-5 Frenzy chance only after a retrigger. The 96.20% RTP build is the standard release version — always confirm the version in the game info panel.
Strategy
Recognise that Feeding Frenzy is the headline outcome, not the expected outcome. Most sessions end without one. Sizing bets so that you can survive 8-12 dives without a Frenzy is the realistic survival math.
| Available At | Depth 4-5 only |
| Per-Spin Odds (Depth 5) | ~15% |
| Common Payout | 500x-2,000x |
| Headline | 5,000x cap |
| Per-Round Chance | ~20% |
Bonus Buy
How to Trigger
Player-purchased entry from the side menu. Cost is around 100x current stake. Availability depends on jurisdiction — UK and several other regulated markets block buy features.
What Happens
Buys direct entry into Deep Dive Free Spins at depth 1, identical to a natural three-Scatter drop. You still have to dive — the buy does not pre-place you at depth 5. Same 10-spin allocation, same retrigger logic, same depth multipliers.
Multipliers
Same depth structure as a natural trigger: 1x → 5x. No bonus multiplier for buying. Average buy outcome sits around 70x-90x stake; long-tail outcomes exceed 1,000x and rare frenzy hits approach the 5,000x cap.
Odds
Cost ~100x, average return ~75x — the math is calibrated against the underlying RTP, so on average the buy slightly trails the cost. Variance is what makes it appealing, not edge.
Variants
Some markets surface a higher-cost super-buy (around 250x) that grants two Deep Dive entries back-to-back. Not a universal release.
Strategy
Useful when you genuinely want Deep Dive content fast and have already accepted the variance. A 500x-1,000x bankroll buffer per buy is the realistic minimum to ride the swings without going dry.
| Cost | ~100x stake |
| Feature | Deep Dive Free Spins |
| Avg Return | ~75x |
| RTP Match | 96.20% |
| Bankroll Buffer | 500x-1,000x per buy |
