Land 3 solar tree symbols on the middle reels to win 7 free spins. You get a re-spin for each losing spin. If you land diamonds, they remain locked in the diamond meter for the duration of the free spins.
Diamond Link Feature
The Diamond Link gives you the chance to trigger one of the jackpots. For the purpose, you need to collect diamonds and fill up the diamond meter, placed above the reels. Once you collect 6 diamonds in one spin, you may win a Mini, Minor, Major or Grand jackpot.
You are given 3 spins to start with. Every time you land a diamond symbol, the number of spins is reset to 3. To win the Grand jackpot you need to uncover 15 diamonds. If you do not succeed in uncovering any of the jackpots, you get a consolation cash prize.
