You and the computer player, Colonel Blotto, have some 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 round.
After each round, if the winner has not 9 tanks yet he wins one tank. In any case, the loser loses one tank. The game continues until one player has only 4 tanks left.
Send your red 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 green armies without showing it. When you have distributed your nine armies, click the "Fight" button.
