Once you get three cards that you can cash in, cash them in on the pause screen but do not unpause. Then go back to your RISK cards. They are still there! Keep repeating to have as many armies as you want.
Uniforms
To unlock secret character's uniforms, defeat them to win a game.
Unlocking Characters
To unlock Secret characters, beat the game by killing someone that had contact with that secret character in real history. For Example, Catherine the Great fought Napoleon, so to unlock Napoleon, beat Catherine the Great to win a game. Simon Bolivar kicked Ferdinand out of South America. So beat Ferdinand to win a game unlocks Simon Bolivar.
