How the Game Plays

Ocean Stacks is a visually polished underwater adventure set against a serene deep-sea backdrop filled with corals and aquatic life. The game utilizes a standard five-reel grid with 20 fixed paylines where winning combinations are formed by landing matching symbols from left to right. The symbols include various shells and sea creatures, with standard Wilds appearing to substitute for regular pay symbols to complete wins. A core part of the experience is the Super-Stacked symbol mechanic, which allows high-value icons to cover entire reels, increasing the potential for full-screen payouts.

Free Spins Explained

The bonus round is triggered by landing three Scatter symbols anywhere on the reels, awarding 10 free spins. Before the round begins, a unique interactive element allows the player to influence the bonus. By selecting shells in a picking game, the player determines which specific symbols will act as Wilds and which will become Super-Stacked for the duration of the feature. This customization allows for different volatility levels within the free spins session.

Treasure Chest Feature Explained

Adding variety to the base game and bonus rounds is the Treasure Chest symbol, which only appears on the fifth reel. When this symbol lands, it opens to reveal an immediate prize. This can manifest as either an instant cash payout based on the current bet or an entry into the free spins feature if the required Scatters haven't already landed.
