Ocean's Treasure
Deep sea adventure slot — underwater treasures, expanding wild octopus and sunken free spin rounds await brave explorers. Dive into the abyss and claim the ocean's hidden riches.
About Ocean's Treasure
Ocean's Treasure is NetEnt's richly crafted deep-sea adventure slot, played across 5 reels and 20 fixed paylines. The game transports players to a luminous underwater world filled with bioluminescent coral, ancient shipwrecks, and the creatures that guard sunken riches. NetEnt's signature visual polish is on full display — the underwater environment glows with colour and life, and the ambient sound design creates an immersive deep-sea atmosphere that rewards extended play sessions.
The centrepiece mechanic is the Expanding Wild Octopus: when the octopus wild symbol lands on the middle reels during the base game, it expands to cover the entire reel, transforming it into a column of wilds that boost multiple paylines simultaneously. During the Sunken Depths Free Spins, the octopus wild becomes stickier and wider — capable of covering two adjacent reels and persisting for multiple spins to create extraordinary win chains. NetEnt's characteristically lower volatility approach means Ocean's Treasure offers frequent base game hits, making it accessible for all session lengths, with the free spin feature providing the notable prize ceiling at 500x.
How to Play Ocean's Treasure
- Set Your Bet: Launch Ocean's Treasure on 777in and select your coin value and bet level using the controls at the bottom of the screen. The minimum total bet is ₹10 across 20 paylines. NetEnt's interface makes it easy to toggle between preset bet levels, so you can quickly find your preferred stake.
- Know Your Symbols: The octopus is the expanding wild. The treasure chest is the scatter symbol. Premium symbols include the deep-sea diver (highest value), the mermaid, the anglerfish, and the seahorse. Lower-value card rank symbols (10, J, Q, K, A) styled as ancient coins complete the reel set.
- Trigger the Expanding Wild: When the octopus wild lands on reel 2, 3, or 4 during the base game, it expands vertically to fill the entire reel. This creates a full column of wilds, boosting any paylines that run through that reel and often triggering multiple simultaneous winning combinations.
- Trigger Sunken Depths Free Spins: Land 3 or more treasure chest scatter symbols anywhere on the 5 reels simultaneously to enter the Sunken Depths Free Spins round. You receive 10 free spins. Scatters during free spins retrigger the feature and add 5 additional spins each time.
- Maximise the Sticky Expanding Wilds: During free spins, the octopus wild expands to cover up to 2 adjacent reels and remains sticky for 1 additional spin after landing. Plan your expectations around these sticky wilds — consecutive free spins with a double reel-wide wild in place represent the highest payout window in Ocean's Treasure.
Strategy Tips
Ocean's Treasure is a medium-volatility title from NetEnt, meaning it balances base game frequency with meaningful bonus feature payouts. Its 500x maximum win is more conservative than modern high-volatility slots, but the trade-off is a smoother, more consistent gameplay experience that is forgiving on bankrolls and well-suited to longer sessions.
Lean Into the Expanding Wild Frequency
The Expanding Wild Octopus triggers directly from the base game without needing a scatter — it simply needs to land on reels 2, 3, or 4. This means base game expanding wild events are a regular occurrence. Identify spin sequences where the octopus appears frequently and consider extending your session during these runs, as expanding wilds often cluster in runs.
Aim for the Retrigger
The real value in Ocean's Treasure is achieved by retriggering the free spins. Starting a retrigger with sticky expanding wilds already active on the reels from the previous free spin creates a compounding effect where high-value base-game symbols land across already wild-covered reels. A double retrigger with two sticky wilds in place is the game's prime payout scenario.
Budget for a Consistent Session
Unlike high-volatility slots that demand deep bankrolls for rare but massive hits, Ocean's Treasure rewards steady, moderate-stakes play. A 60–80 spin bankroll at your chosen bet level is usually sufficient to experience both expanding wild events and at least one free spin trigger. This makes it ideal for players who prefer predictable session structures over high-risk gambling.

FAQ
Ocean's Treasure by NetEnt has a certified Return to Player (RTP) of 96.07%. This is a solid, above-average RTP for a NetEnt slot and means the game returns ₹96.07 per ₹100 wagered over a large statistical sample.

The Octopus Wild symbol can land on reels 2, 3, or 4 during the base game. When it lands, it expands vertically to fill its entire reel with wild symbols, substituting for all regular paying symbols across every payline that intersects that reel. During the Sunken Depths Free Spins, the octopus wild evolves — it can expand to cover up to 2 adjacent reels simultaneously and becomes sticky, remaining in place for 1 additional free spin after it first appears.
The maximum win in Ocean's Treasure is 500x your total bet per round. This is achieved during the Sunken Depths Free Spins feature when two adjacent reel-wide octopus wilds are active simultaneously, covering the majority of the 20 paylines with wild symbols and allowing the highest-value deep-sea diver symbols to complete across all remaining positions. At the minimum bet of ₹10, the maximum payout is ₹5,000.
