How to Play

Gemtastic has simple functionality, so you can quickly figure out what's what. But we still decided to leave here for you a small guide on the slot:

  1. In the "Pays" section, you will find detailed information about payouts and symbols
  2. Click on the bet amount to select it from the list
  3. Then, you need to choose your starting bet
  4. Press the spin button to start the game
  5. The "Turboplay" button will greatly speed up the gameplay

Gemtastic is a slot machine with 6 reels, 5 rows, and 30 fixed paylines. You can choose to bet from a minimum of €0.20 to a maximum of €10. With this information, we can move on to important aspects of the game, such as RTP and volatility, as well as talk about payouts and bonuses.

Gemtastic RTP and Volatility

8 
The slot has an RTP of 95.07% and high volatility.
Experienced players already know very well what these indicators mean. If you see them for the first time, this information is necessary. The RTP of this slot has an average of 95.07%; this percentage shows how much money you can get back from your total bet. Volatility shows your winnings and how often you will receive them. High volatility is, in most cases, a long wait for winnings, but when you get them, you will be very pleasantly surprised. After all, the winnings may be even more than you expected.

Theme

8.1 

The reel is located in a cave almost completely covered with various precious stones. They are literally everywhere, from the cave to the reel itself. Next to the reel is a multiplier indicator, which shows its value with the help of lava. So it has provoked the appearance of such an incredible amount of gems. Of course, the provider ensured that the graphics were of the highest quality and that the gameplay was smooth.

As mentioned earlier, the symbols on the reel are gems. The difference between cheap and expensive symbols is only their size and color. The low-paying symbols are small gems - blue, blue, purple, orange, and yellow. And large gems are expensive symbols - purple, red, green, and amber. The latter is the most expensive.

Symbols of 2x2 or 3x3 size can appear on the reel. The slot has only one special symbol - it's Wild.

Mobile Compatibility

After each winning combination, the value of the multiplier increases by one. But in order for the multiplier to increase significantly, each spin must be winning. The maximum multiplier you can get is 15x.Gemtastic Slot - Multiplier

Magic Radiance Feature

Special characters appear under special conditions. Some regular characters seem to glow. When such regular symbols create a winning combination, and all are on a payline, then they do not just disappear from the reel but turn into Wilds.

Cluster Falls Feature

When winning symbols appear on the reel, they disappear and thus make room for new symbols. Thus, in just one spin, you can get several winnings.
