How do we rate slot machines?
We evaluate slot machines based on multiple criteria, from which we make our final verdict.
Mermaidβs Diamond is a fascinating online slot machine from the developer PlayΒ΄n GO, which focuses on an underwater world full of mysteries and treasures. This slot is popular for its high-quality graphics, innovative game mechanics and exciting bonus features. The game uses a unique reel format that allows for 720 ways to win. Combinations are counted from left to right. The reels are diamond-shaped with a 3-4-5-4-3 configuration.
Who is the manufacturer of the slot machine?
Every slot machine must be manufactured by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific manufacturers, so they narrow down their selection by preferred software manufacturers. In the Czech Republic, the most popular machines are from local software manufacturers such as Kajot or Synot.
What are the Cylinders or Reels on a slot machine?
Reels are the basic element of most slot machines and are columns of symbols that spin and stop on the screen gradually during the game. They are therefore the basic element on which symbols spin and on which winning combinations are formed. The most popular numbers of reels are 3 and 5.
What are paylines and how do they work?
Paylines on slot machines are imaginary lines that run through the reels of the machine and determine which combinations of symbols on these lines are considered winning. As the reels spin, players try to achieve winning combinations of symbols on these lines. Combinations must always start from the left. Each payline has its own payout value, and the winnings are determined by the paytable for each symbol on the particular machine. Modern slot machines can have hundreds of paylines, and players often have the option to choose how many of these lines they bet on.
What is RTP
The RTP of slot machines is a rule of thumb for how much money a slot machine will return to players. Let's say you put 100 crowns in it, the RTP determines how much of that money you should get back. The average value is 92 to 97%.
The game takes you to a mysterious underwater world where sirens and sea creatures await you. The graphics are stunning β the background depicts the depths of the sea, while the reels are surrounded by pearl shells, corals and seaweed. The sound of the game perfectly complements the atmosphere thanks to the gentle sounds of waves and a magical musical background. Classic card values ββin the style of shells are among the low symbols. Precious stones are among the higher ones. The WILD symbol appears to complete winning combinations and thanks to it you can also enjoy a very interesting bonus game. In the case of Scatter symbols, their function remains the same β triggering Free Spins and one great bonus feature. During the free spins, you can collect more Scatter symbols, which will add more and more free spins to you.

The game features special WILD symbols that substitute for all other symbols except the Bonus Scatter symbols, creating the best possible winning combinations depending on the paytable.
Trident Wild Spin Feature
The Trident Wild Spins feature can be activated randomly during any feature game of the base game. During this feature, a random number of special WILD symbols will appear on reels 1-2 in the feature game.
The game features Scatter bonus symbols. If 5 Scatter symbols appear anywhere on the reels, the bonus spins will be activated within 1 regular game. When the Free Spins feature is activated, 5 chests will appear, from which the bettor will select 1 and the number of Free Spins awarded (10, 15 or 25) will be displayed. Your selection does not affect the payout percentage or the outcome of the game. During the Free Spins feature, all displayed Diamond symbols are added to the counter. If 5 Diamond symbols are collected, the Trident Wild Spins feature will be activated after the reels have stopped spinning for 1 bonus free spin.
In Bonus Spin mode, you can get additional bonus spins by landing Scatter symbols. If you land 3 Scatter symbols, you will be awarded 3 more bonus free spins, if you land 4 Scatter symbols, you will be awarded 4 more bonus free spins and if you land 5 Scatter symbols, you will be awarded 5 more bonus free spins.
Divine Intervention Feature
The Divine Intervention feature is purely random. It can be triggered during the base game after a non-winning spin. However, you need to land 4 Scatter symbols anywhere on the reels. If this feature is triggered, a fifth Scatter symbol will be added and the Free Spins feature will be activated.
