To set up play, lay out 25 word cards in a 5×5 grid. Place a key card in the holder so that each player sees one side of the card. Each player sees a 5×5 grid on the card, with nine of the squares colored green (representing your agents) and three squares colored black (representing assassins). Three of the nine squares on each side are also green on the other side, one assassin is black on both sides, one is green on the other side and the other is an innocent bystander on the other side.
