You can win the jackpot payout of 10,000x your stake when you match 5 killer whale icons on the same payline – this means up to 5,000 coins can be yours when you play at Max Bet.


Set your coin level between $0.01 and $0.02 per bet, and activate between 1 and 25 lines; the minimum possible bet on Great Blue is $0.01 per spin, and the maximum is $0.50.

Your game uses icons linked to the sea and card values 9 to Ace, so expect starfish, sharks, killer whales, seahorses, oysters, turtles, and fish in action on the reels.

Your biggest non-jackpot wins are 750x your stake for matching 5 turtles or sharks on a payline, followed by 500x your stake for matching 5 oysters.

Wild: the killer whale is wild and it multiplies all wins it completes x2, as well as awarding its own payouts, including the jackpot. The wild on Great Blue can substitute all icons but the scatter.

Scatter: the oyster can land anywhere, not just the same active paylines, to improve your game. Land at least 3 to trigger free spins (up to 33) and multipliers (max x15) – free spins can be retriggered. The scatter also pays out a win when you land at least 2 oysters on the same payline.
