Wild
The big yellow digger is the wild symbol, it can land stacked on all of the reels, and it will substitute for all of the other symbols, except for the scatter symbol, to help and form winning combinations.
Scatter
The scatter symbol is a glowing blue light.
Bonus Features
The Wild Digger feature is triggered when the wild symbol lands stacked and fills an entire reel. If it helps to form a win then the wild will shift to the right for the next spin, if it doesn’t help to form a win then it will remain in place until it does. The feature continues until the wild digger falls of the right end of the reels.
The Hidden Gems Free Spins begin when you land the scatter symbol on reels two, three and four simultaneously. You win eight free spins and they start with the wild digger fully stacked on the first reel. A second wild will also be added to one of the other reels. During the free spins, any wilds that land partially on the reels are nudged up or down to completely fill its reel. As in the base game, when a wild contributes to a win it will shift one reel to the right and it will remain in place if it does not help to form a win. At the end of the round, any wilds left on the reels remain in place when you return to the base game.
Jackpot
The wild symbol offers the top payout of 125x when five land across the reels. The Space Digger logo can payout up to 100x, the three different digger symbols can all payout up to 40x, the red and purple gems can both payout up to 15x, and the blue and orange gems can both payout up to 10x.
