Help the king save his kingdom and people. Place wizards and knights on the designated spots for an amount of gold to help fend off the enemy waves. Use your two skills to place either bombs or spies throughout the map to help your army along with the fighting. Use skills when they come off cool down and note that they do not have a gold purchase cost, unlike the knights and wizards do. Use the crowns that you collect for beating each level then improve the skill tree tier system that allows you to upgrade your wizard and knight's skills, as well as your bomb and spy's attributes. Have fun!
