Our Great Blue Slot Review

Great Blue is a solid mid-tier ocean-themed slot that delivers reliable entertainment with a respectable 96.03% RTP and generous 10,000x max win potential, making it appealing to bonus hunters who enjoy free spin modes with multiplier escalation. The pick-and-click clam feature during free spins adds strategic depth, though the standard 5×3, 25-line layout and modest betting range (£0.01-£1.25) mean it won't excite high rollers seeking volatility. It's best suited for casual players and balanced play enthusiasts who prioritize accessible gameplay and decent win multipliers over cutting-edge mechanics.
