What Symbol Triggers Great Blue Slot Bonus Free Spins?

Great Blue players merely have to land 3 or more scatter symbols to trigger the free spins feature.

This means getting free spins won’t be as difficult as spotting the prized Great Blue.

Landing 3 scatter symbols during the free spins feature awards Great Blue players with 15 additional free spins.

This bonus feature also awards players with a 2x multiplier, 8 additional free spins, and as much as 500 coins when 5 of a kind land on the reels.

Paylines and Stakes

Great Blue Slot machine has 25 paylines and 5 reels.

To begin the adventure of looking for the great blue, players must first place a bet worth anything between 0.01 to 5 coins per spin.

After placing the bets at Great Blue, players will be plunged into an ocean adventure that will reveal some wild wins along with symbol payouts and a 10,000 coin jackpot up for grabs.

Players who can land 2 to 5 wilds will be awarded amounts varying from 10 to 10,000 coins. This may be as rare as a whale sighting, so it’s best to also keep an eye out for the high and low paying symbols.

The blue whale, turtle, yellowfish, seahorse, and starfish represent the higher-paying symbols, with the blue whale acting as the most valuable one.

He can pay players anything from 2 to 750 coins when 2 to 5 of him lands on the slot reels, whereas the other sea creatures can fetch players a minimum of 2 coins when 2 of a kind lands, and a maximum of 750 coins when 5 of a kind lands.

Card symbols, on the other hand, represent the lower-paying symbols. The A, K, Q, J, 10, and 9 can bring players amounts as much as 150 coins, and as little as 2 coins.
