Attacks, which are represented by Hammers on the Spinner, are a way for players to earn coins while also adding challenge to their friends’ quests to finish their villages.
When you land an Attack on the Spinner, the game will automatically transport you to a village of a random player or friend, and there you will have the option to either attack that player or choose someone else from your Friends or Revenge lists which are displayed at the top of the screen.
Without a shield, an Attack from another player reverts the item back one level. This also removes a Star from the total number the attacked player has acquired. If the player being attacked is protected by a Shield or the Rhino, the oncoming Attack will be deflected and will not damage the Village.
