Diamond Link Mighty Sevens is a five-reel video slot with 25 paylines that comes with progressive jackpots, free spins, and a Win Spins feature.
The Diamond Link progress meter triggers the Diamond Link feature when full, which requires landing 6 blue diamonds in a single spin. This awards 3 free spins and also converts all diamonds onscreen into pink paying diamonds. With each new pink diamond that lands during free spins, the feature resets, allowing free spins to continue. Pink diamond values, including jackpots, pay out at the end of the feature. Landing pink diamonds in all 15 spots on the reels will award the Linked Grand Jackpot, which serves as the game's max win.
Landing 3 Gold Scatter symbols will award a base amount of 7 Win Spins, which function as re-triggerable re-spins which will continue until the player has obtained 7 winning spins. Landing Royal Blue Diamonds during this feature will lock them on the Diamond Link progress meter until the end of Win Spins or the next Diamond Link feature.
