Great Blue Slot Demo Review

Humanity always felt the need for escapism. Games of chance offer a certain level of escape, as you may think about lots of things when making your stakes, but while you’re looking at the spinning reels of the slot machine, you can think only about whether you’re going to win or lose. With online slots, escapism can go even further, aside from providing the sheer gambling joy that allows you to escape from your daily chores, they offer a suitable theme. 

There are slots that offer you to go deep in the jungles and slots that allow you to hit the jackpots in the open space. But the most typical and most enjoyable theme for escapism is the sea. And that’s what the Great Blue slot game is about. Released by Playtech in 2013, these best free slots no download with five reels, three rows, twenty-five pay lines, and the return to player ratio of 96.03% allows the players to win 20,000 times their initial stake while enjoying the deep blue sea. 

How to Play This Slot

Playing the Great Blue slots is extremely easy with its simple control panel. On the left, you have two tables with knots below. The first one displays the number of active lines, which you can change with the knots. The second one displays your per line bet. Your stakes start from a minimum of $0.1, but you can bet a maximum of $2. Next, you have two tables placed one under another. The upper table displays your win, while the lower one showcases your total bet. Depending on your per line bet, your total stake ranges between $0.25 and $50. 

Next, you have the `Auto Spin` button, in case you prefer playing without doing anything. Here you can choose between 10, 25, 50, and 99 spins. When you choose the number of spins, a small `Stop` button, just in case you are happy with your wins in this mode and want to stop to collect them. And the final button is `Spin`. So, playing the game is quite simple. You just make your wagers and press `Spin` or `Auto Spin`. And basic gameplay can bring you more than $100 in payouts on minimal wagers. 

Symbols and Soundtrack

The Great Blue slot doesn’t have a particular soundtrack. Only a simple melody plays while the reels are spinning. It kinda resembles the `Under the Sea` song from `The Little Mermaid` score. There are also musical reactions to winning combinations, which are typical for one-armed bandits in the brick-and-mortar casinos. The soundtrack doesn’t distract you from the game, and there’s no point in switching to silent mode. 

Symbols remain faithful to the Great Blue slot online theme, as most of them are different sea creatures. But, like in most slots, the traditional set of card icons is inescapable. Here they are, the lower-paying characters, bringing you between 5 and 150 in-game coins. The high-paying characters include a Butterfly Fish, a Starfish, a Seahorse, a Turtle, and a Shark. The winning combinations of those symbols can bring you between 40 and 1500 in-game coins. 

Bonus Options

Of course, there are special symbols in the Great Blue game. The Orca is the Wild symbol, and aside from the fact that landing between two and five of them can bring you from 10 to 10,000 in-game coins, it replaces all the symbols except the Scatter. Whenever the Wild substitutes a symbol for finishing your winning combination, your wins double. Thus, let’s say landing four Sharks and the Orca will bring you 3000 coins instead of 1500. But that’s not the end of bonus features. 

The Scatter comes in the form of the Sea Shell, and that’s the icon responsible for the free spins and multipliers. Landing three Scatters on the reel will grant you eight free spins and a 2x multiplier. But landing more than three will take you to the mini-game, where you have to pick one of the Shells on the screen. One of them contains 33 free spins with a 15x multiplier. You can retrigger the mini-game during the free spins by landing more Scatters. 

To figure out how the bonus features work, you can play for free. The Great Blue Slot demo offers the same features as the game for real money, so you can check all the options of the game in the demo mode. But mind that it gets quite addictive. Once you’ve tried the Great Blue free slot, you will get an unbearable desire to play it for money until you get the maximum payout of 20,000 times your original bet. 

Pros and Cons of the Slot

At first glance, the design of the slot feels a bit dated. Considering the graphics, you are more likely to believe that the game was released in 2003 rather than ten years later. While it looks primitive, and you may get little to no interest in trying out the Great Blue slot free play, the game attracts with the payouts. Do the math, and you can figure out that you can win $1 million on the maximum bet. Still, it’s important to take into consideration all the pros and cons of the game before playing it.

  • Impressive maximum payout
  • High return to player ratio
