The jackpot win of 10,000x your stake will be yours after you match 5 of the killer whale (orca) icons on a payline – there’s as many as 5,000 coins waiting to be won when you Bet Max.


Your coin level can be set between €0.01 and €0.02 a spin, with between 1 and 25 lines possible per game. Your minimum Great Blue bet per spin is €0.01 and your maximum is €0.50.

You have sea symbols such as starfish, whales, sharks, seahorses, fish, oysters, and turtles, and card values 9 to Ace - and these determine your payouts.

After the jackpot, your biggest possible win is 750x for 5 turtle icons or shark icons on an active payline. You can also win 500x your stake for 5 oysters in a line.

Wild: your wild icon is the orca (or killer whale) and it doubles all wins. The wild also functions as a substitute, excepting the scatter.

Scatter: the oyster triggers your free spins game (up to 33 in total each trigger) and also multipliers (up to 15x) and also pays you a prize for landing 2 (or more) on a payline.
