The symbol depicting the dancing girls is a wild symbol that can appear on the three inner reels (2, 3 and 4). The wild symbol expands to cover the entire reel on which it lands and can substitute for any other ordinary symbol to help form a winning combination along any line.
When a single wild symbol appears on any reel, a free consecutive re-spin is triggered. The expanded wild symbol sticks (remains in place) during the re-spin.
