The 60s. The Cold War at its peak. The secret services of the world powers sabotage, assassinate, blackmail and intrigue. Only the actions should not come out. Stealth is everything.
Spy Business is a tactical, deductive card game for two spies aged 8 and up. You take the lead of two rival intelligence agencies and try to find out as much information about each other's actions as possible.
At the same time, you are careful to keep your own actions secret. The more explosive an action is, the higher its value and the more important it is that it doesn't come to light.
You may now take turns revealing four cards at a time. Then add up the points of the revealed cards. Every enemy secret goes to your account, no matter who revealed it. The points of the double agent go to the person who uncovered it. However, no points are awarded for the dead end. When you have deducted the minus points from the overlapped cards, whoever has the most points left over wins.
