Wizards vs. Vikings! You’re on the wizard’s side in this war. You have to protect your castle by tapping on groups of wizards of the same color. The more the group, the higher your power! Before the day starts, you may also build some defensive constructions, that will slow down vikings, or cause some damage to them. Between waves you’ll be able to repair damaged buildings. If your wall is ruined – you’ll fail. After a long day of grueling attacks, you can buy some upgrades, that will help you to survive the next day. Think carefully but act quickly!
