iPhone Giveaway of the Day - The Spy - mobile game

Identify the spy!
One or more players are spies and the others will have to find them. Every player who isn't a spy will be given the same word - the spies won't know that word.
Then, every player has to say a word (the spies too) and each and every player will have to find out, who is a spy (doesn't know the word) and who is a normal player.
When the spy finds out the word before the players can identify the spy, they win. Otherwise the players win.
