There are one 2 bonuses in this video slot game called Diamond Cave and Hold’n Spin Bonus.
The Hold’n Spin Bonus is initiated when two, three, or four scattered Diamond symbols from left to right. The initiating reels are locked and the remaining reels re-spin. The reels will re-spin three times unless a Diamond symbol appears after a re-spin. A Diamond symbol on one or more of the remaining reels locks the reel and resets the spin counter to three. If all five reels are locked the Diamond Cave Feature is initiated. The feature ends when the Diamond Cave Feature is initiated or when no re-spins remain.
The Diamond Cave Feature Bonus is initiated by five scattered Diamond symbols. The screen changes where two sets of five icons are placed. One set of icons contains free spins, and the other set of icons contains multipliers. The slot player will select one icon from each set and the number of free spins and the multiplier may be kept, or either or both may be replaced by one additional selection from the remaining sets of four icons. The highest possible number of free spins and multiplier, if chosen, is automatically awarded to the slot player. Free spins are paid from a bonus paytable and are played automatically at the same number of lines and bet per line as the initiating game. All pays, except for the top award, are multiplied by the selected multiplier. Five scattered Diamond symbols re-initiate the Diamond Cave Feature. If the bonus is re-initiated the remaining free spins are completed, the two sets of five icons reappear, and a new number of free spins and multiplier are selected and automatically played. The Hold ‘n Spin Feature is active during the Diamond Cave Feature. The bonus ends when there are no free spins remaining and free spins have not been retriggered or 300 free spins have been played. Average pay calculation is based on optimal strategy.
