Great Blue Slot Review

The slot is noted for its high 94.3% RTP and medium volatility. It offers straightforward gameplay, with wild symbols that substitute for all symbols except scatters and pay out up to 10,000x the stake for five in a row. The highlight is the Sea Shells free spins feature, triggered by three or more scatter symbols, where players first receive eight free spins with a 2x multiplier. They then pick two out of five shells to reveal additional free spins or higher multipliers up to 15x. More free spins can be won indefinitely if three more scatters land.

Great Blue slot FAQ

What’s with the dated graphics and sounds?

Great Blue was one of the first online slots created by Playtech in the early 2000s. So while the visuals and audio feel outdated compared to newer games, the slot has an old-school charm and simplicity that keeps players coming back.

Why is there no story or theme progression?

Unlike many modern video slots, Great Blue opts for straightforward spinning action rather than an elaborate backstory or character progression. This allows players to jump right into the main action.

Do the high RTP and volatility lead to consistent payouts?

With a 94.3% RTP and medium volatility, Great Blue provides a healthy mix of small, medium, and large payouts. However, as with any slot, wins and losses can happen in unpredictable streaks rather than a consistent pattern.

What is the relevance of the killer whale symbol?

The friendly killer whale represents the game’s wild symbol. As whales are powerful marine creatures, the wild appropriately doubles any winning combinations it substitutes in.

Why are sharks and turtles special symbols?

Along with their high payouts, the shark and turtle only require two matching symbols for a win (unlike other symbols which require three). This makes them particularly valuable for scoring win
