Two computer players 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.
In this simulation, the player A (with green tanks) plays optimally whereas player B (with red tanks) distributes the armies randomly.
