The appearance of three or more Diamond symbols triggers the 10 free spins feature. In this mode, you will get additional winnings and collect diamonds. The more you collect, the higher the probability of winning the progressive jackpot. The bonus game will start after the completion of the free spins mode. In the bonus round, you will fight for the jackpot. The display on the three reels must meet one of two combinations of Maxi or Mini. Each of them is responsible for a progressive jackpot.
