Double Symbols
During Free Spins, the first reel will include Double Symbols. Double Symbols count towards 2 ways of any win using their respective symbol.
Reel Set
The slot features a 6x4 reel set, where the 6th column is made up of 4 individual spinning reels, which can contribute to winning combinations. If all 4 reel positions in the 6th column show an O symbol, there is a chance for all the O symbols in this column to transform into vault symbols.
Vault Feature
When all 4 O symbols in the 6th column transform into vault symbols, the Vault Feature will be triggered. Choose a Vault to reveal a base number of Free Spins to play with. Vaults contain 4, 8, 12 or 16 Free Spins as an award. Extra Free Spins can be awarded. 1 Free Spin will be added to the current number of Free Spins for every 0 symbol which landed on the first 5 reels. The Free Spins Feature will begin once the total number of Free Spins has been calculated.
Free Spins
Free Spins are played automatically, using the initiating stake and using the base game payouts. Free Spins can only be triggered through the Vault Feature. Free Spins are played using the same award card as the base game. The Vault Feature can be retriggered during Free Spins, suing the same method as the original trigger. The Vault Feature is awarded and played immediately. Additional Free Spins awarded from the Vault Feature are added to the current total of Free Spins remaining. The Free Spins Feature will continue with the new total of Free Spins. Wild symbols do not appear on reel 1, or on any reels in the 6th column during Free Spins.
