Players lay out track tiles in a 9 x 9 grid. They then run their trains over the tracks, consuming any vacant track tiles they pass over as well as their starting point. Some repositioning of tracks and trains is allowed however, when all the players are unable to move, the player with the most track tiles collected wins the game.Corner tiles, edge tiles, and internal tiles can easily be differentiated for grid setup. Each has different point values assigned for movement. - BoardGameGeek
