Gameplay

This Playtech developed slot features 5 reels, 3 rows and 25 selectable paylines. It follows a fun and colourful underwater nature theme, with sea life symbols and special scatters and wilds. It includes a gamble feature which lets you bet on each win, and the 3 or more scatters will trigger a bonus round with automatic free spins or multipliers upon entry, as well as additional bonus picks where you can add more spins or multipliers to your round. Further free spins can be triggered infinitely during existing free spins. Wilds provide rewarding payouts, as well as double payouts for all wins.

Conclusion – A Simple but Rewarding Slot Experience

The theme adds a splash of bright colours to your screen and the animated symbols keep the spins interesting. The graphics are a little outdated and at times slow, but what Great Blue lacks in visuals, it makes up for in payout frequency. The sound effects are rather basic, but unintrusive – the bubbly sound effects will take you underwater, and the steel drum spin music is upbeat and reminiscent of an old arcade game. The number of spins is adjustable for auto play. Tell us what you think about this slot in the comments!
