Each player only knows his agent ant tries to keep his identity secret. The active player rolls the die and moves a minimum of one agent. If he moves a agent to the safe, a scoring takes place. Each agent receives information in the form of scoring points according to the number of the building next to him, in the ruins he loses points. After the scoring the safe is moved. If an agent reaches the start/finish again, the game ends and the player owning this agent wins the game.

Top Secret variant: You can receive a new top secret card instead of moving. After dice rolling, top secret cards can be played and resolved, if so desired.

Secret Dossier variant: You win, if you gather as many informations on agents as you can and can unmask them. Can be combined with Top Secret variant.
