Each player selects one of four Guilds to infiltrate, Thieves, Assassins, Alchemists or Fools. The guild selected will determine which 5 of the spells you seek and a special power which will help in your search and hinder your opponents. Players compete to the be the first to return their 5 assigned Great Spells to the Unseen University. To do so they will need to charm or bribe volunteers to help them, as well as make use of spells, curses, magic items and other odds and sods. While running around the streets of Ankh Morpork they must also beware of other players, as Saboteurs, Great Dragons, the Luggage (of course) and many varied other things can wreak havoc on even the best-laid plans.
On their turn a player will move, may take actions such as buying scrolls, equipment, bribing or charming a volunteer, collecting money, going to the hospital to be cured and many more, and then resolve any special effects. At times players will want to co-operate with one another, and at other times they will be doing their utmost to foil, trip, harangue or otherwise confabulate each others' plans.
The player who manages to successfully return their assigned Great Spells to the Unseen University will be regarded a hero of Ankh Morpork!
