The first American railroad companies had to face a real challenge - link the two coasts of one of the largest countries in the world and overcome the rough conditions on the way. Ticket to Ride, a board game later transferred into computer version, takes a vague stab at that theme, but with simplified rules so several people of different age would be able to play it. The rules are very simple - on the map of United States (or in other versions Europe, Asia, etc) the major cities are connected with lines of different colours that represent the railroads. At the beginning each player is given a task of linking two of those cities, which is one of the ways to succeed in the game, because there are different activities that will give player the points, f.e. the length of the railroads that he have build. The players take turn to draw the cards that represent the train cars in one of the colours (or joker card that can be used on any colour). Once player has enough cards in same colour to link two cities he builds his railway between them. Since the players do not know what bigger goals their competitors have and what cards do they have it is all about the strategy and planning.
While Ticket to Ride is a train-themed game the trains themselves are used only as a medium to between players and the board - the concept of the game is so universal that in some versions whole world is a map and ships are used to connect between the railways. Overall a simple game that quickly gained a lot of recognition and can be fun for whole family due to many ways player can win.
