Irish Gauge - one of three titles in Winsome Games 2014 Essen Set - is played on a map of Ireland and is similar in style to many of the stock-based cube track games released by Winsome Games since 2007.

Each player's turn can trade with one of the five companies up for auction, build a track (represented by cubes) in one of these five companies, upgrade a village to a city, or ask for a dividend. The dividends are paid to shareholders of certain railways based on the number of cities/towns they are connected to and how many shares of this company have been issued. The upgrade and dividend promotions also affect the playing time and the likelihood of further dividends for each company. The game ends when a certain condition is met at the end of a player's turn and the player with the highest sum of money and stock value at the end of that turn wins the game.

Irish Gauge is the first title in Capstone Games' Iron Rail series.
