81 is your lucky number? Then today must be your lucky day!

Diamond Mystery – 81 Boosting Jokers, a four-reel slot by Greentube, has exactly 81 win lines. That means there’s ample room for winning combinations – three or more matching game symbols side by side. However, should the various fruits, the Bell and the 7 not line up correctly for you, they’ll at least offer you a chance at the Diamond Mystery feature. In this special extra, four different jackpots are waiting to be won – all you need are three identical gemstones. And the Joker Lady can give your luck a helping hand as the game’s Wild symbol.
