Mystery Symbols, Re-Spins and three Free Spin Features!

Large stacks of Mystery Symbols on each reel change to a single symbol every spin. Matching full stacks lock and award re-spins; additional stacks retrigger the feature with all Mystery Symbols matching the locked stacks. Free Spin symbol stacks award 5, 10 or 15 free spins with Re-Spins where Mystery Stacks always match.
