The Wild symbol, the SUN, matches all symbols except for the Bonus symbol: That way it can complete your winning combos. The Bonus symbol acts as Scatter and triggers free games when it lands at least three times in any position on the reels.
Three Scatter symbols (symbols marked “Bonus”) trigger eight free games, four Scatters trigger twelve and five Scatters trigger 20 free spins. Scatters only appear on reels one, three and five on both reel sets. During free games all Wild symbols of the first reel set expand to the entire reel they land on and are then transferred to the second reel set. For example, if a Wild symbol appears on reel one and two of the first reel set it occupies all reel positions; afterwards all symbols of the first and second reel of the second reel set are turned into Wild symbols also.
The RTP is 96.02%.
