In Irish Gauge, each player's turn consists of either placing a share of one of five companies up for auction, build track (represented by cubes) in one of these five companies, upgrade a town to a city, or call for dividends. The dividends are paid out to shareholders of certain railroads based on how many cities/towns they connect to and how many shares of this company have been issued.
The upgrade and dividend actions also affect game length 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 this turn wins.
