In Leprechaun’s Castle, the players are noble family members in Ireland. These Lords and Ladies will score points by being the first to reach castles that contain Leprechauns before their close competitors. They will build and travel on roads between castles while collecting gold coins, pots of gold, and shamrocks. By carefully choosing from the available actions, players will draw road tiles and attempt to explore castles without getting caught by an Evil Leprechaun. Players will use their special abilities and plan their turns to locate the most shamrocks. These brave souls may escape the clutches of the Evil Leprechaun but not even the luck of the Irish can save them from a Banshee!
The game system allows players to choose from the available six actions, but players may not take more than four. The available actions are: place a road, travel to a castle, exchange one road, destroy one road, draw an Exploration card, or spend a pot of gold.
