Underwater Pirate Adventure by Push Gaming - Where Ghostly Crews Guard 25,000x Treasure
Sea of Spirits introduces an innovative layered frames system never seen before. Bronze frames appear during base game spins, randomly overlaying any reel position. During free spins, the game escalates with Silver and Gold frames - each tier unlocking different multiplier potentials and symbol splitting mechanics. Bronze reveals standard prizes, Silver splits symbols into two positions, while Gold frames explode into three positions with multipliers from x25 to x10,000.
Three distinct activators transform your frames: Wild Activator converts all frames into Wild symbols for massive combination wins. Symbol Sync Activator populates every frame with identical high-paying symbols - imagine six positions suddenly displaying the Pirate Captain symbol. Coin Activator triggers the Coin Reveal Feature where frames spin through instant prizes, multipliers up to x10, and collector symbols that aggregate all visible prizes.
Push Bet modes available: Bonus Boost (96.23%) raises trigger chance 2.5x | Mega Bonus Boost (96.41%) multiplies Super Bonus triggers by 55x
Triggered by landing three green Bonus symbols anywhere on reels during base game or Coin Reveal. First spin guarantees minimum 3 Bronze frames that remain sticky throughout all 5 spins. Frames never nudge during bonus rounds. Ways expand from base 4,096 up to 2,985,984 potential win combinations as frames populate the grid.
Land two Bonus symbols plus one multicolored Super Bonus symbol to unlock 8 spins with mixed-tier frames. Initial spin adds 3+ frames across Bronze, Silver, and Gold tiers. Silver frames split paying symbols into doubled positions. Gold frames triple symbol positions while restricting instant prizes to x25 minimum values. After first spin, only Bronze frames appear.
When Coin Activator hits, every frame on screen spins independently through prize options: instant prizes from x1 to x10,000, multipliers x2/x3/x5/x10 that multiply all visible prizes before removal, Collector symbols that absorb all instant prize values then trigger respins. During base game, Bonus and Super Bonus symbols can appear in Coin Reveal for immediate feature triggers.
Random activation at bonus start - screen glows intense cyan announcing Overpowered status. Dramatically increases appearance rates of high-value instant prizes, gold frames, and multiplier symbols. Push Gaming does not disclose exact percentages but player reports indicate 3-5x higher frequency of x1000+ instant prizes during Overpowered rounds.

Increases your base bet by exactly 50% - if playing 1.00 bet, Bonus Boost costs 1.50 total. In return: Bonus Feature trigger probability multiplies by 2.5x, Super Bonus trigger doubles at 2x. RTP adjusts to 96.23%. Math analysis: standard base game triggers Bonus approximately every 185 spins; Bonus Boost reduces this to roughly every 74 spins. Best for players seeking frequent 5-spin bonuses over maximum volatility.
Quadruples base bet plus 100% - transforms 1.00 bet into 5.00 total wager. Bonus Feature trigger chance increases 9.5x while Super Bonus probability explodes to 55x normal rate. RTP rises to 96.41%, highest in the game. Super Bonus becomes dramatically more common than regular Bonus under Mega mode. Estimated Super Bonus trigger drops from approximately 1 in 950 spins to 1 in 17 spins. High-risk, high-reward option targeting 8-spin Super Bonus sessions with mixed-tier frames.

Cost: 500x base bet | RTP: 96.34% | Launches 8 Super Bonus Spins with mixed Bronze/Silver/Gold frames appearing on opening spin. Higher RTP than regular Bonus purchase compensates for 5x cost increase. Silver and Gold frames provide symbol splitting and premium instant prize floors.
Cost: 500x base bet | RTP: 96.35% | Activates immediate 24-position Coin Reveal Feature - maximum possible frame coverage. Every position spins through instant prizes, multipliers, and collectors. No base game required. Highest single-feature RTP in the buy menu. Upgrader symbols included exclusive to this purchase mode.
Cost: 150x base bet | RTP: 96.32% | Spins wooden wheel with three outcomes: 50% chance No Prize (returns to base game), 25% chance 5-spin Bonus Feature, 25% chance 8-spin Super Bonus. Weighted toward no prize but costs only 1.5x standard bonus purchase while offering Super Bonus possibility. Gambler's option.
Grid Configuration: 6 reels by 4 rows with 4,096 ways calculation in base game. Win evaluation requires matching symbols on adjacent reels starting leftmost position - minimum 3 adjacent reels for payout. Ways expand exponentially during bonus features as frames split symbols: Silver frames double symbol positions (2,985,984 maximum ways), Gold frames triple positions.
Frame Behavior: Base game frames nudge downward one position per spin until exiting bottom of reels. Bonus and Super Bonus frames lock in place (sticky) for entire feature duration. Frames cannot stack - only one frame per reel position. Activator symbols create new frames in their landing position if no frame present.
Win Cap Mechanism: Maximum single-round payout capped at 25,000x current base bet amount, not total bet including Push Bet additions. If natural combinations would exceed 25,000x, payout automatically adjusts to cap. This ceiling affects approximately 0.01% of spins based on probability distribution. All RTP calculations include win cap impact.
Upgrader Function: Appears only in bonus features and Coin Reveal during Bonus Buy. When activated outside Coin Reveal, upgrades random quantity of frames one tier level: Bronze to Silver, Silver to Gold. Gold frames cannot upgrade further. During Coin Reveal, Upgrader lands as prize option, upgrades the frame containing it, then disappears allowing new prize spin.
Most underwater slots recycle standard free spins with fixed multipliers. Sea of Spirits architect Push Gaming built a three-dimensional frame ecosystem that evolves mid-game. Bronze frames in base play establish position memory - they nudge downward each spin, creating anticipation as activators can hit while frames remain visible. This nudging mechanic alone generates more strategic depth than typical hold-and-respin systems.
The activator variety prevents feature monotony. Wild Activator suits combination-focused players who maximize payline coverage. Symbol Sync targets those seeking synchronized high-value symbols across maximum positions. Coin Activator appeals to instant-prize enthusiasts who prefer direct multiplier awards over symbol combinations. Having three distinct activation paths means bonus rounds never play identically.
Frame tier progression from Bronze to Silver to Gold creates genuine escalation. Silver's symbol-doubling transforms a single Pirate Captain into two paying positions. Gold's triple-split means one compass symbol occupies three grid spaces, dramatically increasing combination potential while restricting instant prizes to x25 floor - preventing low-value dilution in premium frames. This tiered structure rewards players who reach Super Bonus with qualitatively different mathematics.
Coin Reveal Feature operates as nested game-within-game. Each frame becomes independent slot spinning through 13 possible instant prize values, 4 multiplier options, plus Collector symbol. Multipliers apply to all visible prizes before self-removing, creating sequential multiplication chains. Collector appears, absorbs all instant values, triggers respins for empty positions. This creates emergent gameplay where prize order matters - landing x10 multiplier before x5000 instant prize generates 50,000x position value before base bet multiplication.
Standard play without Push Bet expects Bonus Feature approximately every 185 spins, Super Bonus roughly 1 in 950 spins. Budget minimum 200x base bet for reasonable bonus trigger probability. Frame nudging means activators hitting during frames' 4-spin descent window offer multiple payout opportunities from single frame set.
Bonus Boost mathematically sound for players prioritizing spin quantity over max-win chasing - 50% bet increase for 2.5x trigger frequency nets positive expected entertainment value. Mega Boost better suits short sessions targeting Super Bonus: 55x trigger multiplier means 17-spin average versus 950-spin base rate. Choose based on bankroll depth and session length.
Guaranteed Coin Reveal at 500x base bet with 96.35% RTP offers most consistent returns due to 24-position coverage and Upgrader symbol inclusion. Bonus Chance Wheel at 150x presents gambler's fallacy temptation - 50% no-prize chance means expected loss despite Super Bonus possibility. Direct Super Bonus purchase at 500x justified when specifically seeking 8-spin sessions with mixed frames.
