How to Play

DiamondZ works simply, but better take a look below and check out exactly how.

The slot has 5x3 reels with 20 paylines. You can find all possible winning lines under the goblet sign. The min bet is €0.12 and the max is €80.

  1. Check your balance and set the bet size in the cells under the playing field
  2. The amount of your wins in each spin will display nearby. All amounts are displayed in euros
  3. The block of yellow buttons: 1st – to immediately place the maximum bet; in the center – to make a spin; the last yellow one allows you to choose the number of autospins or stop them
  4. Round buttons on the sides give you info about the game, and the far-right will help you adjust the sound

DiamondZ RTP and Volatility

8.7 

Volatility varies from medium to high with an official RTP of 96.15%.

In the base game, you can expect medium to high volatility with an average RTP of 96.15%. Such an indicator is not the highest for a slot. But you always have the option to catch the bonus round or gamble feature to increase your chances of winning bigger.

Theme

8 

No doubt, DiamondZ is a bright slot. Cool mix of classic fruit game and trendy diamond theme. You will appreciate the soft dynamics of the dark blue background, clear interface, crystal sounds, and tender theme melody. And of course, what makes this game - juicy fruits and bright diamonds with nice 3D rendering.

A set of fruits and a lucky 7s are the main game symbols. All diamond signs act as bonus elements. For example, 3 diamonds set in gold are a special DiamondZ symbol. And the jester acts as a Wild symbol that you can catch on reels 2, 3, 4, and 5. It will replace any fruit symbol to increase the chances of a winning combination. But at the same time, it won't help with the replacement of Scatter and Diamondz.

The diamonds that appear on the reels have their meaning. To be exact – from 0.25x to 10x of the total bet. But the main advantage of Scatter is the ability to launch free spins.

Bonus Rounds & Free Spins

8 

Free Spins

Did you get 5 or more Scatter symbols on the reels? Place and combination are not important here, the main thing is availability. The spins will be played at the same bet as for the base game. Free spins can be re-triggered. Max up to 50 spins at a time. This feature can be retriggered up to 50 free spins at a time!

Diamondz symbols need to be hunted down. You will meet these shiny pebbles only in the bonus game. Each symbol is equal to a Scatter combination that triggered the bonus game.

Gamble Feature

Another bonus is a mini-game. An invitation to the bonus game may appear after each winning combination.

Test your intuition and guess the color of the card suit. If you guess the color, you will double your win.

In the bonus game, it is possible to play for half the amount per round, and the second can be credited to the balance.
