Each player has three 'agents' who must "spy" at a location indicated by one of the cards in their three-card hand (cards are replaced once played).
Points are scored according to a clock on the game board... one o'clock only scores 1 point, 12 o'clock scores 12 points. The hour hand advances one hour for each agent moved during a turn.
If your score is between 13 and 63, agents may "rendezvous", (when more than one agent is at a location when it scores, it will double or triple the points scored).
The first player to 100 points is the winner.
