A grid of tiles are placed face-down with four stations in the corners. Players in turn take a face-down tile into their hand and choose to play it or a reserve track tile face-up in the position just vacated. The tile can be rotated in any direction they choose. Each player holds a secret hand of routes from station to station. When their routes have been completed, they are the winner. A light tile placement game for fans of Ticket to Ride and Tsuro. Simple enough for children 5 and up. Similar in mechanics to Indigo.
