There are two scatter icons, a bonus symbol and a wild in this slot. The wild is the golden coin, and it is a standard wild icon, replacing itself for all other icons in the slot, with the exception of the two scatters and bonus icon.
The leprechaun is the first scatter, and when three or more appear anywhere on the reels, the player will trigger the Road to Riches bonus. Here the player must dash down a yellow brick road; with the further they get landing them more money.
The wishing well bonus is triggered by the second scatter (a wishing well). Landing three or more of these icons triggers a pick-and-win bonus round. Finally, a third bonus round is triggered by the pot of gold bonus icon. This symbol loads a spinning wheel, which offers the player a pot of bronze, silver or gold (coins) plus a bonus multiplier.
