How to Play

Start playing Clash of Gems in several steps:

  1. Load the game on your device
  2. Adjust the game volume
  3. Learn rules and other slot info
  4. Set your wager and start spinning the reels

In Clash of Gems, you have 5 reels with 4 rows. To win you need to land 3 symbols on one of 10 fixed paylines. With Wilds, it is easier to gather winning combinations.

Clash of Gems RTP and Volatility

7.7 
Clash of Gems features high volatility and an RTP of 96%.
The more you risk the higher rewards you can get. That is common in gambling. And the same is volatility. In Clash of Gems, it is high, meaning that prizes can be huge. However, the chance to miss is also high. Meanwhile, RTP is a theoretical possibility of winning bet value back during a spin. And the Return to Player of Clash of Gems is 96%. Together with volatility, these parameters deliver balanced gameplay to players.

Theme

7.9 

Clash of Gems has a simple theme, which brings you to a valley of crystals and gems. It focuses your attention not on the background and arts around but specifically on symbols. Each one has a different and excellent design. Ambient music and sounds complete the overall theme.

Symbols in Clash of Gems require additional attention. The low-value category consists of card suits, which provide 0.4x, 1x and 2x multipliers. The mid value consists of Red, Blue and Yellows gems with 1x, 4x and 8x. And this slot has one high-value symbol Seven with 5x 10x and 20x. Special symbols in Clash of Gems can greatly change your reward.

  • Wild: drops anywhere on the reels and substitutes missing symbols. It may also trigger Expanding Wild feature.
  • Gempot (scatter): rewards you with jackpots depending on the number of symbols on reels. And it is scattered, so you don’t need to have it on a payline.
