The object of the game is to visit as many of the principal cities of the world in as short a time as possible, starting from London; to purchase a souvenir of each place visited and return home to London when an agreed number of souvenirs have been purchased. Travel is made by Air, Sea, Rail and Road. Tickets are purchased at any of the appropriate ticket offices, or at Thomas Cook & Son, and money may be changed at a Bureau de Change, the Bank or at Thomas Cook & Son. Travelers run all the risks of international travel; having unexpected luck en route or encounter complications with customs and local regulations. Players must also change currency frequently throughout the game.
