Great Blue™

In Playtech's Great Blue™, players engage with a video slot featuring a 5-reel by 3-row layout and 25 adjustable paylines. The game immerses you in an underwater realm filled with symbols representing various marine creatures, including whales, sharks, turtles, seahorses, starfish, and seashells, all set against a vibrant aquatic background. The Orca whale serves as the Wild symbol, capable of appearing stacked and substituting for all standard symbols except the Scatter, while also doubling any wins it contributes to. The Scatter symbol is represented by an Oyster with a pearl, and landing three or more of these anywhere on the reels activates the Sea Shells Bonus. This bonus grants 8 free spins accompanied by a 2× multiplier, followed by a pick-me game where players select two out of five seashells to uncover potential upgrades, including extra free spins up to a total of 33 or multipliers reaching up to 15×. During the free spins, players have the chance to retrigger the bonus by landing additional scatters, which can add 15 more spins while maintaining the same multiplier. Additionally, after any winning spin, a Gamble feature allows players to risk their winnings for a chance to double them through a card-colour-picking game. Achieving the maximum win in Great Blue™ involves landing five Wilds on a payline, which can yield up to 10,000× the line bet.
