Main Theme and Storyline

The slot's anime theme turns the simple slot into a game with appealing graphics and animations. The grid is located in the sky in front of the castles, and the princess on the left side dances during each winning combination. The slot is vibrant due to its bright colours, visual effects and cheerful sounds, which play when you win or activate bonus features.

Gems Sky Slots features & Bonus games

As for a relatively classic slot, Gems Sky offers quite a lot of bonus options, such as Walking Wilds during Free Spins, the Accumulated Feature and others. We tried out all of them to explain their mechanics below.
  1. Random Wilds

    The feature is triggered randomly, spreading two or more Wilds, the cat symbols, across the grid. It’s beneficial since Wilds serve as symbols that can help form a winning combination.

    Gems Sky slot Random Wilds At any spin, the slot can randomly bring 2+ Wilds to the gaming field, providing for more winning combinations

  2. Free Spins

    Upon landing three or more Scatters, symbols with a princess, players receive 10 Free Spins.

  3. Random Walking Wild

    During FS rounds, Wilds appear, disappear, and move to any position on the reels. Thus, each spin gets additional potential for getting a winning combination.

  4. Wheel of Fortune & Jackpots

    The presence of the wheel symbols triggers the Wheel of Fortune feature. Then, players spin the wheel, which can bring Mini, Minor, Major, or Grand jackpots, paying up to 1,000 times.

  5. Hold and Ring

    This feature is triggered when you land five bonus symbols in the form of coins with stars. During the Hold and Ring mode, winnings are equal to the sum of multipliers specified on these symbols.

  6. Accumulated Feature

    Bonus symbols accumulate, and when this feature is active, they randomly replace symbols, increasing your winning potential.

RTP, Bet Sizes and Volatility

  • The 95.20% RTP is slightly below the market average.
  • The minimum bet of €0.20 is not the smallest, but it will still be suitable for new players, while the €100 maximum cap is ideal for those with large bankrolls.
  • Players should consider high volatility and be prepared for a long session with infrequent yet potentially significant wins.
The slot has a relatively small 1,000x max win
Yet, this amount is more achievable compared to larger ones, mainly due to bonus features available during the main game or as separate options.

Our Final Thoughts on the Game

We were amazed by the slot’s vibrant theme and the loads of animated elements that appeared during winning combinations. The settings are pretty simple, and we believe that the RTP and winning potential could be higher. Nevertheless, it was nice to experience Random Wilds in the main game. Plus, other bonus features are diverse, from Free Spins to Wheel of Fortune with four jackpot levels.
