Clacks: A Discworld Board Gameis based on the "Clacks" semaphore messaging system — the fastest (non-magical) messaging system on the Discworld — featured in Sir Terry Pratchett's novelGoing Postal.
Using a semaphore system of shuttered lamps on top of high towers, the Grand Trunk Semaphore Company has revolutionized long-distance communications on the Discworld. Their network of towers covers most of the Unnamed Continent, but now the old postal service is fighting back. Driven by the determination of newly "volunteered" Post Master Moist Von Lipwig, the Ankh-Morpork Post Office has challenged the Clacks operators to a race from Ankh-Morpork to Genua.
Play against your friends and claim the title of Fastest Clacks Operator on the line, or play together as a team to win the race across the Discworld and prove that Clacks is here to stay. In more detail,Clacks: A Discworld Board Gamecontains rules for a player vs. player game, a co-operative race game against the Post Office, and a children's introductory game.
