Option 2; Medium Volatility: 8 free spins with a minimum of 8 guaranteed wilds
Option 3; High Volatility: 4 free spins with a minimum of 10 guaranteed wilds
Option 4; Random: 12, 8 or 4 free spins with a minimum of 6, 8 or 10 guaranteed wilds is chosen at random
However many wilds are selected or awarded, this will be the minimum number of wilds in view for every free spin.
Additional wilds can also land randomly on every free spin.
Each guaranteed wild is assigned a random position on the reels for each free spin.
During free spins, multiplier symbols are collected by the player.
Collecting a specific amount of multiplier symbols progressively moves the player through a series of multiplier levels.
Each multiplier level has a multiplier range assigned to it.
When the free spins bonus is over, a multiplier from that specific range is awarded.
The multiplier value is applied to the total won amount during the free spins round.
Anything won in the base game spin that triggered free spins is not subject to this multiplier but is added to the final win amount after the multiplier has been applied.
The specific amount of multiplier symbols that need to be collected to progress through the levels is dependent on which free spins option is chosen;
if 6 wilds are awarded, the option 1 criteria is used
if 8 wilds are awarded, the option 2 criteria is used
if 10 wilds are awarded, the option 3 criteria is used
The multiplier range for each level is the same regardless of which option is selected;
Level 0: 1x the players bet
Level 1: between 2x and 5x the players bet
Level 2: between 5x and 8x the players bet
Level 3: between 8x and 11x the players bet
Level 4: between 11x and 14x the players bet
Level 5: between 15x and 18x the players bet
Level 6: between 18x and 21x the players bet
Level 7: between 21x and 24x the players bet
Level 8: either 24x, 26x, 28x or 30x the players bet
Level 9: either 30x, 35x, 40x or 100x the players bet

After level 12 is completed, multiplier symbols may still land on the free spins reels but they will not be collected.

There is no cap on the amount of times free spins can be retriggered.
Free spins rounds total bets are the same as the total bet placed before triggering the bonus.
Free spins will end if the maximum sum of wins value is reached.
