Try to take over entire territories: you will earn more armies at each reinforcement that way.
Watch your enemies. If they are building up large forces near your borders, expect an attack soon!
Fortify your borders well. This will provide the best defense against your enemies.
Do not spread your armies too thin. While expansion is the object of the game, you do not want to expand too quickly. Spreading your armies too thin makes it easier for your enemies to steal your cities.
To attack, you must chose which city to attack from the attack page and which city you are attacking. Next you must decide how many armies you are attacking with. You must attack with anywhere between one army and total armies on your city minus one. The number of attacking armies determines how many armies will move into your enemies nation if you defeat it and how many dice you will get to roll. If you atttack with one army, you can roll one die, two armies roll two dice, and three or more armies roll three dice. The more dice you roll, the greater your chance of winning but also, the greater number of armies you can lose and the greater number of armies you must move. The defender will be allowed to roll one die if they have one army of the city and two dice for two or more armies.
To decide a battle, the highest dice are compared in order. If the attacker's die is higher, then the defender loses an army. If the defender's die is higher. the attacker loses an army from the attacking nation. In case of a tie, the defender always wins.
