Dive beneath the waves with Lord of the Ocean, Green Tube's underwater twist on the classic book-style slot format. This mythological adventure takes players into Neptune's realm, featuring the signature free spins bonus with expanding symbols and an impressive 10,044x stake maximum win. The game delivers underwater treasures across 5 reels, 3 rows, and up to 10 paylines, with betting options ranging from 2p to £20 per spin on all devices and platforms.
Green Tube (Novomatic) has crafted an aquatic adventure that brings the beloved book slot formula to the ocean depths. Lord of the Ocean maintains the core mechanics that made the series famous while introducing a captivating underwater theme centered around ancient mythology.
This medium to high volatility slot operates on a 5x3 grid with up to 10 adjustable paylines, though we strongly recommend activating all lines for optimal winning potential. Players can enjoy flexible betting from 2p to £20 per spin, making it accessible across different bankroll sizes.
The slot includes a classic gamble feature allowing you to risk winnings up to 5 times in a double-or-nothing card color prediction game. The main attraction remains the free spins bonus with its chosen expanding symbol mechanic, offering unlimited retriggers and the potential for massive wins up to 10,044x your total stake.
The game transports players to Neptune's underwater kingdom, featuring symbols inspired by Greek and Roman mythology. All wins require 3-5 matching symbols on active paylines, with the following payout structure:
• King Neptune (Lord of the Ocean) - Premium symbol paying 5,000x for 5 on a payline
• Scatter/Wild Symbol - Dual-function symbol awarding 2,000x for 5 anywhere on reels
• Mermaid Queen - High-value symbol delivering 2,000x for 5 on a payline
• Treasure Chest - Mid-tier symbol worth 750x for 5 on a payline
• Warrior Statue with Spear - Another mid-tier paying 750x for 5 symbols
• Card Suit Symbols - Lower-paying icons offering 100x to 150x for 5 on a payline
The scatter symbol serves double duty as both wild and bonus trigger, substituting for regular symbols while also activating the main feature.
Lord of the Ocean keeps the base game relatively straightforward while focusing on its powerful special features:
Wild/Scatter Symbol: This dual-purpose icon substitutes for all regular symbols and awards direct payouts up to 2,000x your stake when 5 appear anywhere on the reels.
Gamble Feature: After any winning spin, players can choose to risk their winnings in a classic double-or-nothing card game. Simply predict whether the next card will be red or black - guess correctly to double your win, guess wrong to lose everything. You can gamble up to 5 consecutive times, potentially multiplying modest wins into significant payouts.
The gamble feature adds an extra layer of excitement for risk-taking players, though conservative players can always collect their wins immediately.
The free spins bonus serves as the slot's centerpiece, triggered by landing 3 or more scatter symbols anywhere on the reels during a single spin.
Triggering Rewards:
• 3 scatters = 20x stake + 10 free spins
• 4 scatters = 200x stake + 10 free spins
• 5 scatters = 2,000x stake + 10 free spins
Special Expanding Symbol: Before the free spins begin, the game randomly selects one regular symbol to become the expanding symbol. During free spins, this chosen symbol expands to fill entire reels wherever it lands, creating additional winning opportunities.
Unlimited Retriggers: Landing 3+ scatter symbols during free spins awards another 10 spins with no maximum limit on retriggers. This creates the potential for extended bonus rounds and accumulating massive wins.
The combination of expanding symbols and unlimited retriggers makes this feature the primary source of the game's 10,044x maximum win potential.
While Lord of the Ocean doesn't offer progressive jackpots, it compensates with substantial fixed win potential. The slot's maximum payout reaches 10,044x your total stake, following the tradition established by other book-style games in the series.
With the maximum bet of £20 per spin, lucky players could potentially win up to £200,880 from a single spin. This impressive ceiling typically occurs during the free spins feature when expanding symbols align perfectly across multiple reels.
The high volatility nature means big wins may be infrequent, but the potential rewards justify the patience required for this underwater treasure hunt.
Lord of the Ocean delivers exactly what fans of book-style slots expect - reliable mechanics, exciting bonus features, and significant win potential wrapped in an appealing underwater theme. While it doesn't revolutionize the formula, it executes the classic design exceptionally well.
The medium-high volatility suits players who enjoy the anticipation of big wins, while the 10,044x maximum payout provides genuine excitement. The unlimited retrigger potential in free spins adds extra thrills to each bonus round.
