Reel Expansion Feature
The initial reel window is three symbol positions high.
Reels will expand to six symbol positions high should a Key scatter symbol appear on them.
The Key symbol disappears once the reels have expanded, and all empty reel spaces are filled with symbols that fall in from above, in sequence.
Reel symbols that fall from above contain all symbols, excluding Key symbols.
The reels can display more than one Key symbol, but only one Key symbol may land on each reel on a given spin.
When no more Key symbols are shown on the reels, symbols will stop falling into empty reel spaces.
Wins are evaluated once, after the reel expansion and all symbols have fallen. The reel window remains six symbol positions high on the upcoming spin.
The reel height decreases one position on each subsequent spin, until it returns to three symbol positions high.
If a Key symbol lands on the spins that follow, that reel expands to six symbol positions high and it causes the sequence to reset.
Reel heights in the base game are saved separately for each bet level and remain between play sessions.
Mystery Symbol Feature
The reels may contain Mystery symbols on any spin, and they have the ability to transform into any symbol with the exception of Key, Bonus, or Wild symbols.
Mystery symbols that appear on all reels will all transform into the same symbol.
After the transformation of all symbols, wins will be evaluated.
MultiWay Xtra Feature
With the MultiWay Xtra feature, there are 243 to 7,776 ways to win on every spin, based on the Reel Expansion feature.
MultiWay Xtra wins pay for matching symbols in any position in adjacent columns, and this begins with the leftmost column. The award will be multiplied if there is more than one matching symbol in the same column.
With the exception of the Key, Mystery and Bonus symbols, the Wild symbol can be used as a substitute for all symbols.
You will only be paid for the highest paying MultiWay Xtra win for each symbol on each spin.
Free Spins Bonus
To trigger the Free Spins Bonus, a minimum of three Bonus Scatter symbols must land in any position on the reels.
Number of Bonus Symbols
Free Spins Awarded
When at least two Bonus Scatter symbols are displayed anywhere on the reels, the Free Spins Bonus is re-triggered.
Number of Bonus Symbols
Extra Free Spins Awarded
You can re-trigger this feature on a number of occasions, up to a maximum of 200 free spins per bonus.
The Free Spins Bonus starts with a three symbol position-high reel window initially. During the Free Spins Bonus, the Reel Expansion feature works identically to way it operates in the base game.
The Free Spins Bonus begins with an accumulating multiplier value of 1x. For every Key symbol that is displayed in the active reel window, a 1x multiplier value is awarded that adds to the accumulating multiplier.
Throughout the Free Spins Bonus, reel symbols that fall from above may contain all symbols, and Mystery symbols could potentially transform into Key symbols.
More than one Key symbol may land on the reels, and more than one Key symbol may hit on each reel in the Free Spins Bonus, and they will each award a 1x multiplier.
All symbols continue to descend until no Key symbols are present on the reels.
Wins are evaluated after each free spin, following any reel expansions, falling symbols, Mystery symbol transformations, or multiplier increases. The accumulating multiplier value is used to multiply all wins.
Reels used in the Free Spins Bonus are not the same as those active in the base game.
Your free spins are played with the same coin value that was used in the spin that triggered the feature.
When no free spins remain, or after 200 free spins have been played, the bonus will conclude.
