Sparkling Stones and Shining Gems
7Rings Gaming is the provider behind this new slot. The Heart of Gems slot machine is an excellent example of the studio’s visual design skills.
Gems-themed slots might not sound like the most exciting, but 7Rings Gaming have put a lot of focus on the visuals here, and they’ve successfully made them engaging and easy on the eye. Brightly colored stones serve as symbols in the Heart of Gems online slot spin across the 5x4 grid, while floating stones in the backdrop hint at something magical bubbling under the surface.
Unlock Bonus Reels
The Heart of Gems slot machine RTP is set at 96.04%. You can place bets as low as 0.20 coins or as high as 100 coins.
Piles of gems can land with values of 2x, 5x or 10x. These are collected by scatters and paid out as instant wins.
Wilds can substitute for any symbol except scatters. When part of a win, wilds will replace the highest-value symbol.
Landing three scatters will trigger the bonus game as you play the Heart of Gems slot online. During this feature, every position on the grid acts as an independent reel, creating a total of 20.
The grid is split into four zones, and each position can land a Pile of Gems or the Mini (20x), Middle (50x), Max (150x) jackpots. Filling a zone with symbols will increase the round's overall multiplier by 1x.
