During the game, players must fill up the Diamond meter – located at the top of the screen. Once six diamonds are collected, the Diamond Link feature is activated. Within this mode, players are awarded with three Free Spin, with every additional diamond symbol that lands resetting the counter back to three. If the player is able to fill the entire reel set with Diamonds, then they win the Grand Jackpot. 

Furthermore, if the Scatter symbol – the diamond with a Wild Spin logo – lands on the reels, a Free Spin is awarded with a guaranteed win. During the spin, a random number of Wild symbols are randomly distributed across the reels to help complete winning combinations. 

Moreover, if the Scatter lands with a Sticky Spin logo, all winning symbols are locked in place and the reels spin again. This repeats until the entire reel set is filled with a winning combination. 

Alternatively, another variation is the Colossal Spin logo. Once this lands, a Free Spin is awarded, during which the middle three reels show a giant symbol that covers a 3×3 position, while reels one and five spin again. 


Boro Brumen, head of games product at Greentube, commented: “This beautifully designed game transports players to a mystical, ancient realm and offers the chance to win major prizes.

“Within the attractive packaging is a game of real depth. Diamond Link: Mighty Emperor takes the hugely popular Hold N Spin feature to the next level and we are excited to see how players react to the evolved mechanic and the opportunities it presents.”
