Two players have 9 armies each. These can be sent to four battlefields of about equal importance. The player sending more armies to a battlefield wins it. The player winning more battlefields wins the game.
The computer player, Colonel Blotto, owns the 9 armies depicted by green tanks. Your armies are illustrated by the red tanks. Send the armies to the four battlefields by clicking the corresponding "+" buttons. You can also remove them by clicking the "-" buttons. The computer player will at the same time distribute his armies without showing it. When you have distributed your nine armies, click the "Fight" button.
