Heist: Guard gems while investigating white areas to discover where the thief’s hideout is. Easy: Beat 5 thieves or beat the hideout to win. On later difficulties, you have to find the hideout. Tips: If your attacking a third or clearning an ambush, be mindful of who you call. You don’t want to call someone guarding a gem, a thief can steal it at any time. You also have 60 seconds to respond to a thief’s attack and unlimited time to respond to a hideout attack.
White Circle: Within this circle somewhere lies the hideout. The more you investigate, the smaller the circle gets.
Black Circle: This means the thief is somewhere inside there, make sure to send heroes because the thief could attack at any time.
