Yggdrasil Gaming has unveiled a new slot to its portfolio of titles, “which promises monstrous cascading wins huge enough to make the very ground beneath your feet shift and shake.”

Gem Rocks features big wins tumbling down reels, with the help of a series of gentle hearted giants, who can turn into symbol clusters.

With each winning spin the symbols will cascade down, while hitting consecutive wins in a row can guarantee gigantic blocks of up to 4×4 symbols to drop to the most profitable positions for the player.

Jonas Strandman, Yggdrasil Gaming Head of Slots, said: “Gem Rocks is custom-made for players who prefer high variance slots and love the thrill of big wins.

“We are sure the exciting win streaks, win-guaranteeing monster clusters and over 9000x bet wins will keep the players coming back to this gem time and time again.”

Yggdrasil details that Gem Rocks has launched on its established HTML client framework iSENSE 2.0+, and will be backed by its collection of in-game promotion tools, Boost, which are designed to boost retention rates for all operators.
