Features of the Great Blue slot

The game takes place on a screen a 5 vertical rollers e 3 horizontal lines. The payment lines are 25 and can be changed according to the needs of the individual player (starting from a minimum of 1 active line). By choosing a fewer number of active lines, of course, the basic bet will be less.

The episode range therefore varies from a minimum of 0,01 $ to a maximum of 50 $null From the rather limited choice we understand how this game was designed for cautious players.

Although the range may not satisfy the most courageous users, it is noted that The payments table offers higher amounts to the average, therefore potentially the win could reach more than interesting levels.

Great Blue Slot: Payout and combinations

The Payout offer and the winning combinations are two of the most characterizing features of the videos. The choice of the player is often based on these data, being fundamental to understand how much one can actually win ..

In the case of GBS all these elements are verifiable By accessing the game regulations, which shows itself to the user in two different versions. L'icon with the gear, located at the top right of the screen, offers more technical information, while the complete review of images is entrusted to the "info”, Placed at the bottom left of the main screen.

Payment table and lines

The table of the regulation, accessible in a graphic version from the key Information or with more technical explanations from the icon gear Any possible winning combination is explicit within the game, also offering a detailed explanation of the bonus games provided for by the same.

The graphic table is divided into three sections:

  • Paytable;
  • Paylines;
  • Sea Shell Bonus.

The first explicit the minimum and maximum winning winner with the individual symbols, the second shows an image of all the available payment lines and the third explains the functioning of the bonus activated by the Scatter.


Videoslot is characterized by Marine -themed symbols, accompanied by others that indicate the letters of the real poker and offer minor winnings. In particular:

  • Shark Paga Da 2x a 750x;
  • Turtle Paga Da 2x a 750x;
  • Seahorse paga da 15x a 250x;
  • Starfish paga da 15x a 250x;
  • Clownfish pays from 20x to 400x.

For minor symbols, however, we find the following values:

  • A e K pagano da 10x a 300x;
  • Q, J e 10 pagano da 5x a 100x;
  • 9 Paga and 2x in 100x.

All these values they are doubled If the combination on the winning line is made with the presence of a Wild symbol.

Great Blue Slot game bonus

Remaining faithful to the mechanics of simple and traditional spin, GBS does not have extra features that upset standard games. However, we noticed that the Jolly symbol and the Scatter can optimize winnings in an excellent way that can be made with basic bets or if the free laps are activated. In detail:

  • l’orca It is the Jolly of Videslot and replaces all the other figures, helping in the formation of combinations on a winning line. Pay from a minimum of 10x to a maximum of 10,000x the initial bet. According to the information already obtained on the Payout, therefore, the most profitable card is far;
  • l’oyster with pearl Instead, it is the scatter that activates the special free laps function. Before that, however, the player is asked to choose 2 between 5 closed oysters. These reveal the free spin multiplier and the number of the same. The pearl is also a paying icon and returns from 2x to 500x.


La videoslot Does not include a jackpot, whether this fixed or progressive. This lack could certainly make the nose turn up, since those who play are often used to its presence in slots with the most basic dynamics, but thehigh level of the Payout It compensates it effectively.

Many Videslot, among other things, do not foresee that the Jolly and the shots offer prizes, which instead also happens with a certain generosity in GBS. The choice of the Playtech not to add even a jackpot, we agreed, can therefore be easily forgiven.

Great Blue Slot Free Spin

I spins free They are certainly the most loved by those who play videooslots. Not to aim for your money for each single spin, in fact, it is a not indifferent advantage and allows you to win decidedly higher prizes than those provided for by the standard match.

In GBS the free spins (or free laps) are activated when they land on the grid 3 or more shots icons, represented by oneOyster open and containing a precious pearlnull After choosing, with a small mini game, Multiplier e number of free matches, the same begin as soon as the "spin" key is activated.

The extra mode can be potentially reactivated to infinity, since the appearance of 3 other shots icons are added to the free turns already in progress 10 games.

Theme and graphics

Il Marine theme It dominates the scene, showing itself in the dark blue background, with bubbles that liven up the screen and characterizing all the icons of the videoslot. There graphics reminiscent of 3D, rounded and colorful, but offers a right mix with it stile cartoon, which makes the gaming experience carefree and lively.

The sound elements, in turn, are fitting and the classic jingle of the rollers is made lighter and recalls the bubble sound, the same that date back from the background. The music is actually made with one xylophone, but we thought that this element was perfect for the proposed theme and really remember the atmosphere of a holiday on a Caribbean beach.

RTP and volatility

The regulations on online casino software impose stringent requirements of RTP, i.e. the potential return to the player, and volatility, which indicates the frequency of payments.

In the Games Playtech, always in possession of an ADM license, it can be sure that these requests set in the laws are respected. The minimum RTP, in fact, asks for a percentage of 90% and the slot Great Blue offers an excellent 96.03%.

When at the volatility is high, that is, payments are less frequent, but offer higher amounts. An excellent compromise, therefore, also considering the remarkable return to the player.

Come Vincere a Great Blue Slot?
