Slot Glossary
35 terms covering Pirates' Plenty: The Sunken Treasure's Treasure Reel unlock (5→6), Wild Ships with multipliers, Wild Monkey upgrades, Ocean Spins with progressive chests, and the path to 4,359x.
Autoplay
Spin the reels automatically for a set number of rounds. Useful for grinding map symbols toward the 50-symbol Treasure Reel unlock on Pirates' Plenty: The Sunken Treasure, or chasing the ~1-in-260 scatter trigger that opens Ocean Spins. Optional stop conditions include stop on Treasure Reel unlock, stop on Ocean Spins, or stop on Wild Monkey landing.
Base Game
Standard play before Ocean Spins triggers on Pirates' Plenty: The Sunken Treasure. Pre-unlock, the base game runs 20 paylines on a 5×3 grid. Post-unlock (after collecting 50 maps), the grid expands to 6×3 with 20 still active and Wild Ships sailing onto reel six. High volatility throughout.
Bonus Buy
Pirates' Plenty: The Sunken Treasure doesn't offer a traditional bonus buy. The path to Ocean Spins runs exclusively through natural 3-scatter triggers (~1 in 260 base spins) or via 100x bet purchase where supported. RTP holds at 95.70% regardless of trigger path.
Bronze Chest
Pirates' Plenty: The Sunken Treasure's first-tier Ocean Spins chest. Turns card royal symbols (10, J, Q, K, A) into wilds for the duration of the free spins round. Unlocked first by collecting keys during Ocean Spins. The chest tier system progresses: Bronze first, then Silver, then Gold.
Cascading Reels (Tumble)
Pirates' Plenty: The Sunken Treasure doesn't use cascading reels. Wins resolve once per spin via the 20 paylines on the 5×3 (or 6×3 expanded) grid. The replay action comes from Ocean Spins retriggers and Treasure Reel unlock progression rather than in-spin cascades.
Cluster Pays
Pirates' Plenty: The Sunken Treasure doesn't use cluster pays. Wins resolve through 20 paylines on the 5×3 (expands to 6×3) grid. Cluster pays would require connected groups of matching symbols anywhere; Pirates' Plenty: The Sunken Treasure keeps the line-win format with Wild Ships and Wild Monkey providing the value-escalation mechanic.
Dead Spin
A spin returning nothing. Pirates' Plenty: The Sunken Treasure's high volatility produces dead spins around 70% of the time at base game. Even dead spins can show map symbol landings — those maps don't pay but feed the Treasure Reel counter, providing background progression toward the 6th-reel unlock.
Feature Trigger Rate
How often Ocean Spins activates on Pirates' Plenty: The Sunken Treasure. Natural trigger from 3+ scatters: ~1 in 260 base spins. Treasure Reel unlock occurs after collecting 50 map symbols (typically 200-400 base spins depending on map drop rates). Both progressions run independently.
Free Spins
Ocean Spins is Pirates' Plenty: The Sunken Treasure's free spins equivalent. 3 scatters trigger 10 free spins with treasure chest keys progressively unlocking Bronze (card-to-wild), Silver (multiplier wilds), then Gold (full reel transformation). Each chest level stacks on top of the previous one within the same round.
Gold Chest
Pirates' Plenty: The Sunken Treasure's top-tier Ocean Spins chest. Transforms entire reels into solid wild columns. Unlocked third in the chest progression — requires both Bronze and Silver chests opened first. The Gold chest provides the highest single-spin payout potential within Ocean Spins.
Hit Frequency
How often Pirates' Plenty: The Sunken Treasure produces any winning combination. Hit rate sits around 30% — about 1 in 3.3 spins pays something. Standard for high-volatility line-based designs. The Wild Monkey appearance dramatically boosts effective win frequency by upgrading low-value spins on the fly.
Map Symbol
Pirates' Plenty: The Sunken Treasure's collection mechanic. Every map that lands on the reels feeds a counter at the top of the screen. Once the counter hits 50, a sixth reel slides open on the right and the grid shifts from 5×3 to 6×3 for the rest of your session. The expansion isn't a timed bonus.
Max Win
The absolute maximum a slot can pay on a single round. Pirates' Plenty: The Sunken Treasure caps at 4,359x. The path runs through Ocean Spins with Gold chests active, stacked Wild Ships on reel six carrying x5 multipliers, and Wild Monkey appearances chaining together for premium-symbol upgrades.
Max Win Cap
Once Pirates' Plenty: The Sunken Treasure hits 4,359x, the round ends immediately. The 4,359x cap is modest by 2026 standards but reachable through the Treasure Reel + Ocean Spins layering. Red Tiger deliberately constrained the peak to fit the steady high-vol session feel.
Megaways
A Big Time Gaming licensed mechanic with up to 117,649 ways to win. Pirates' Plenty: The Sunken Treasure doesn't use Megaways — it uses 20 fixed paylines on a 5×3 (expandable to 6×3) grid. Red Tiger has Megaways-licensed titles in their catalog but Pirates' Plenty: The Sunken Treasure stays with the line format that fits the Treasure Reel mechanic.
Multiplier
A value that multiplies your win. Pirates' Plenty: The Sunken Treasure's Wild Ships carry x2, x3, or x5 multipliers, applied to every winning combination they contribute to. Wild Ships only appear after Treasure Reel unlock and stack across positions on reel six. Silver chest during Ocean Spins adds multiplier wilds across the grid.
Ocean Spins
Pirates' Plenty: The Sunken Treasure's flagship free spins round. 3 scatters trigger 10 free spins with treasure chest keys. Each key opens progressive chests: Bronze converts card suits to wilds, Silver introduces multiplier wilds, Gold transforms entire reels. Each chest level stacks on top of the previous one.
Paylines
Predefined lines across the reels where matching symbols form a win. Pirates' Plenty: The Sunken Treasure runs on 20 paylines on a 5×3 grid (expandable to 6×3 via Treasure Reel unlock). Lines pay left-to-right starting from reel 1. All 20 lines remain active across both grid sizes.
Paytable
The reference chart showing each symbol's payout for matching combinations. Access through the game's info menu. Pirates' Plenty: The Sunken Treasure's premium symbols (pirate captain, ship, treasure) pay the most. Mid-tier symbols include pirate imagery (skull, parrot, anchor). Card royals (10, J, Q, K, A) fill the bottom across the 20-line layout.
RNG (Random Number Generator)
The cryptographic algorithm determining every spin outcome. Red Tiger uses GLI-certified RNGs — independently audited for fairness. Each spin in Pirates' Plenty: The Sunken Treasure is independent of the last; previous map symbol counts or scatter landings have zero influence on future spins.
RTP (Return to Player)
The theoretical percentage of wagered money a slot returns over millions of spins. Pirates' Plenty: The Sunken Treasure runs at 95.70% — slightly below the 96% industry standard. Red Tiger publishes this figure openly. Some operators run different configurations, so verify in the game info screen before spinning.
Scatter
A special symbol that triggers features regardless of payline position. Pirates' Plenty: The Sunken Treasure's scatter symbol triggers Ocean Spins when 3+ land anywhere on the reels. Scatters don't count toward the Treasure Reel map collection — that's a separate map symbol with its own counter.
Session Variance
The gap between actual results and theoretical RTP. Pirates' Plenty: The Sunken Treasure has 95.70% RTP, but a 200-spin session can return 30% to 250% of your wager. High volatility means session swings are significant. The Treasure Reel unlock progression provides a secondary variance source beyond standard bonus triggers.
Silver Chest
Pirates' Plenty: The Sunken Treasure's second-tier Ocean Spins chest. Sprinkles multiplier wilds across the grid for the duration of the free spins round. Unlocked after Bronze in the chest progression. Multiplier wilds stack with Wild Ships on reel 6 (post-Treasure Reel unlock) for compound multiplier effects.
Sticky Wild
A wild symbol that stays in place across multiple spins. Pirates' Plenty: The Sunken Treasure doesn't use traditional sticky wilds — but the Treasure Reel unlock provides the most persistent change in the slot: once unlocked, the 6th reel and Wild Ships remain active for the rest of your session.
Treasure Reel
Pirates' Plenty: The Sunken Treasure's headline mechanic from 2019 — a slot that literally grows while you play it. Collect 50 map symbols to unlock a hidden 6th reel. Once unlocked, it stays active for the rest of your session, expanding the grid from 5×3 to 6×3 permanently. Wild Ships only appear after this unlock.
Volatility (Variance)
How a slot's payouts are distributed. Pirates' Plenty: The Sunken Treasure is rated High — meaning longer dry stretches between wins, with payouts concentrated in Ocean Spins and Wild Monkey appearances. Released 2019 — Red Tiger's variance design philosophy concentrates value in the bonus mechanics.
Ways to Win
An alternative to fixed paylines. Pirates' Plenty: The Sunken Treasure uses 20 fixed paylines, not ways-to-win. Red Tiger has ways-based titles in their catalog but Pirates' Plenty: The Sunken Treasure stays with the classic line layout that complements the expanding-grid mechanic.
Wild
A symbol that substitutes for any regular symbol to complete winning combinations. Pirates' Plenty: The Sunken Treasure's wild design includes standard wilds (substitute), Wild Ships (stacked + multipliers, post-Treasure Reel only), Wild Monkey (random appearance, removes low-value cards), and chest-unlocked wilds (Bronze converts cards, Silver adds multipliers, Gold transforms reels).
Wild Monkey
Pirates' Plenty: The Sunken Treasure's value-upgrade mechanic. Randomly appears during base play, swings across the board, and substitutes broadly — covering several positions in one move. Removes all low-paying card symbols (10, J, Q, K, A) and replaces them with higher-value pirate symbols. Dramatically increases average win value.
Wild Ships
Pirates' Plenty: The Sunken Treasure's multiplier wild mechanic. Only appear after Treasure Reel unlock — stacked Wild Ships sail in over reel six column with x2, x3, or x5 multipliers stamped on each one. They drag their multipliers into every payline they touch.
Win Distribution
How total payouts are spread across different win sizes. High-volatility slots like Pirates' Plenty: The Sunken Treasure concentrate value in features — Ocean Spins contributes ~35% of total RTP, Wild Monkey appearances ~20%, Wild Ships post-unlock ~25%, base-game payline wins ~20%. The Treasure Reel mechanic shifts RTP distribution after the unlock.

Pirates' Plenty: The Sunken Treasure's grid format. Starts at 5×3 = 15 cells. Once 50 map symbols collect, expands to 6×3 = 18 cells permanently.
