The Shells bonus round

When this round starts, you automatically get 8 free spins that can double your prize. Next, you're asked to choose two out of five shells. Depending on your choice, you can increase the number of free spins to 33 and the multiplier to 15. The free spins round starts right after this game ends.

Bonus mode with free spins

Free spins are launched automatically, without your involvement. Your winnings for combinations are multiplied by the multiplier you had in the bonus game. If you land three or more Scatters during the round again, you get 15 more spins but with no prize multiplier. When the round ends, you get the winnings transferred to your balance.

The Great Blue Slot Symbols

The Great Blue slot themed to ocean has 13 thematic symbols. To make things easy to understand and convenient to see, consider the bet per line to be 1 credit when thinking of payouts for symbol combinations. The regular symbols of the slot game are cards and inhabitants of the deep sea. All the symbols except for the nines, sea turtles and sharks, can form combos of 3, 4 and 5 symbols. You can get the following payouts in credits for certain regular symbols:

  • Nines pay 2, 5, 25 and 100
  • 10, J, Q - 5, 25 and 100
  • K and A - 10, 50 and 150
  • Seahorse and starfish - 15, 75 and 250
  • Yellow fish - 20, 100 and 400
  • Turtle and shark - 2, 25, 125 and 750

Scatter is a pearl in a shell. By landing 2, 3, 4 or 5 Scatters on the reels in a random order, you get 2, 5, 20 or 500 times the total bet. Furthermore, three or more Scatters trigger the bonus round with free spins and multipliers.   

The Wild symbol is a killer whale. It substitutes for any symbol except for the Scatter. Combinations with the Wild symbol double your prize. Its own combos pay you 10, 50, 2,500 and 10,000 credits for 2, 3 4 and 5 symbols lining up on the screen.

Gambling Round

You can play the doubling game by clicking Gamble whenever you have a winning combo. You are asked to guess the colour of a face-down card. You can pick the colour using the Red and Black buttons. If you guess it right, your winnings are doubled and you can proceed with the gambling round. Otherwise, you lose your winnings.

How to Play the Great Blue Slot

The Great Blue online slot was developed by Playtech with a free demo available to play for fun at Before you spin the reels for the first time, you should adjust the bet per spin using parameters such as bet per line and the number of lines. The total bet is the price of a single spin, namely the number of credits you can adjust and will be deducted from your account every time gameplay starts. You will face the virtual currency denomination while configuring the bet. The two types of currency in the game are credits and coins. Coins are used to set the bet per line and are automatically converted into credits with a special value multiplier, which is set by the player. To set the value of one coin, click the Click to change button in the bottom left corner and choose one of these options - 0.01, 0.02, 0.03, 0.04, 0.05, 0.1 or 0.25. In the future, we will use the coin worth 0.1 credits to describe bet settings and payouts for certain symbol combinations.

The bet per line is an essential setting which you can adjust by clicking the Bet per line button. It varies between 0.1–1 credits. The higher this factor is, the more you pay for a spin and win for a winning combination. The Lines button lets you choose from 1 to 25 paylines. This feature is pretty simple - more lines means higher chances to win. So having the spin cost set to the minimum and having all the paylines active, the total bet is 2.5 credits.

Before you spin the reels, read through the game rules, including the guide on the bonus round and gambling round. You can do so by clicking the Info button in the bottom left corner to open the reference menu. The paytable doesn't recalculate the payouts automatically and displays them as bet per line multipliers.

Starting the Game

The Spin button launches a single reelspin in the game window with the chosen settings of the total bet. One more click stops the spinning process. The Bet Max button sets the maximum betting settings and launches a single spin with them. To activate the auto-play mode, you should set up the number of automatic spins using the + and - buttons, choose from 1–99 spins and click the Auto start button. If you need to interrupt the auto-play, click the Stop button.

The Great Blue video slot features common payouts, a bonus round with free spins and a prize multiplier, ordinary graphics and background music. Discover the secrets of how to play for real money and win in online casinos by reading the NeonSlots real money page.
