Clash of Gems: A Sparkling Slot Adventure from Merkur


Step into a world of radiant riches with Clash of Gems, a visually striking online slot from the renowned German provider, Merkur. This game transports players to a fantastical realm where precious stones are not just symbols of wealth but the very source of magical power. While the official RTP for this title is not publicly listed, it features a medium volatility model, making it an attractive choice for players who enjoy a balanced mix of frequent smaller wins and the potential for more substantial payouts. With 20 fixed paylines and a betting range that accommodates both cautious newcomers and high rollers (from €0.10 to €100 per spin), Clash of Gems offers a versatile and engaging slot experience. In this comprehensive review, we'll explore every facet of the game, from its enchanting gemstone theme to its special features, providing you with all the information you need to enjoy the Clash of Gems demo right here on Slottomat.

Theme, Visuals, and Sound Design


Clash of Gems presents a unique fantasy aesthetic that blends classic slot symbolism with a touch of arcane mystery. The reels are set against a backdrop of ancient stone, perhaps deep within a forgotten temple or a mystical cavern. The symbols are the true stars, featuring a dazzling array of gemstones—rubies, sapphires, emeralds, and topaz—each meticulously designed to sparkle and catch the light. Complementing these are more traditional slot icons like the BAR symbol and the number 7, all reimagined with a crystalline, jewel-encrusted finish. The soundtrack is an epic, orchestral score that builds tension with each spin, complete with satisfying sonic effects for wins and special feature triggers. The overall production quality is high, creating an immersive atmosphere that feels both familiar and fresh.

Game Symbols and Payouts


The paytable in Clash of Gems is divided into low-paying and high-paying symbols, all consistent with the gemstone theme. The lower-value symbols are the classic playing card icons (10, J, Q, K, A), but they are crafted from polished metal and adorned with small gems. The higher-value symbols are the gemstones themselves and the special 7 and BAR symbols. Landing a combination of five matching high-value gems can yield a significant return on your bet. As with many Merkur slots, the game also features special symbols that are key to unlocking its most exciting features, which we will explore in the next section. The 20 fixed paylines ensure that winning combinations can be formed in numerous ways across the 5x3 grid, keeping the action consistent and engaging.

Special Features and Bonus Rounds


While Clash of Gems may not have a complex array of bonus rounds like some modern video slots, it focuses on delivering impactful features that can dramatically alter the course of a spin. The two primary features to watch for are:



  • Wild Symbol: The game's logo acts as the Wild symbol. It can substitute for any regular paying symbol to help complete winning combinations across the 20 paylines. This can often turn a near-miss into a satisfying win.

  • Clash of Gems Feature (Respin Feature): This is the centerpiece of the game. When two full stacks of the same high-paying gemstone symbol land on reels 2 and 4 simultaneously, the Clash of Gems is triggered. The two stacks "clash," causing the gemstones to shatter and transform into Wild symbols. These Wild-covered reels then lock in place, and you are awarded a free respin with the remaining reels spinning again. This feature can create a screen full of Wilds, leading to massive win potential, especially if additional matching symbols or Wilds land on the respin.


This respin mechanic is a classic and effective bonus, offering a clear moment of heightened anticipation. For players who enjoy features with a higher risk and reward profile, you can learn more about such mechanics in our High Volatility Slots Guide.
