Rules and Gameplay

Lucky Ocean is a captivating slot game developed by Onlyplay, setting players on an underwater adventure with a unique gameplay mechanism. Unlike traditional slots, Lucky Ocean utilizes a lottery/scratchcard approach across its 4×7 layout, creating an engaging experience. Players start with a default stake of 10 coins, which can be adjusted from 1 to 50 coins based on budget and preference. The absence of an Autoplay feature means each spin requires manual action. The goal is to navigate through seven rows of air bubbles, making correct selections to avoid the hedgehog fish and achieve a maximum payout.

Bonus Features

Although Lucky Ocean takes an unconventional approach to slot gaming, it does not include a wide range of traditional bonus features. However, its unique gameplay itself serves as an exciting feature:

  • Lottery Mechanic: Instead of free spins or wilds, players engage in a turn-based game, selecting bubbles in hopes of avoiding the hedgehog fish.
  • Risk and Reward: After each successful selection, players can choose to continue for greater rewards or collect their current winnings.

This straightforward yet thrilling mechanic ensures every round is filled with suspense and decision-making.


The symbol system in Lucky Ocean is simplistic, focusing on two primary symbols to drive the game’s narrative and winnings:

  • Pearl Symbol: Occupying three out of four bubbles in each row, the pearl symbol signifies a win, allowing players to either collect their winnings or gamble for more.
  • Hedgehog Fish Symbol: Representing the game’s element of risk, the hedgehog fish symbol ends the game immediately if selected, adding a layer of suspense with every choice.

This minimalistic approach to symbols complements the game’s unique gameplay, focusing players on the excitement of the chase rather than complex symbol combinations.


Lucky Ocean deviates from traditional slot games by not featuring conventional paylines. Instead, the game operates on a lottery/scratchcard basis where the outcome is determined by the player’s selections rather than aligning symbols across pre-defined paylines. This innovative approach offers a fresh take on slot mechanics, focusing on player choice and strategy.

Game Jackpot

The Lucky Ocean slot features an intriguing jackpot system as part of its lottery-style gameplay, although it does not offer a progressive jackpot commonly found in other slot games. The RTP (Return to Player) is set at 96.2%, and the game’s variance is described as adjusted, striking a balance between frequent smaller wins and the occasional larger payout.

How To Play

  • Start by setting your bet size using the “+” and “-” buttons to adjust your wager according to your preference.
  • Once your bet is set, press the spin button to begin the game. The reels will start spinning and then come to a stop, revealing the symbols.
  • In Lucky Ocean, your goal is to uncover pearls while avoiding the hedgehog fish across seven rows of air bubbles. Each row contains four bubbles, three of which hide pearls, and one conceals a hedgehog fish.
  • If you select a bubble containing a pearl, you can choose to continue to the next row or collect your winnings. Progressing increases your potential payout but also risks losing to the hedgehog fish.
  • The game ends if you decide to collect your winnings or if you uncover a hedgehog fish, concluding your current play session.
