Visiting friends becomes available upon completing the special quest "Visiting de Albert". You will be able to visit as many allies per day as you like. To visit your friend, open the Allies menu (icon in the bottom menu with a picture of two people), tap on your friend’s avatar, and you will be transported to the player's village. To help your friend, select the buildings th have resource icons above them. You may keep some of these resources. Please, remember that the number of activities you can perform while visiting each friend is limited. The amount of actions left is shown on the icon in the top-left corner of the screen (under the experience and happiness indicators). To return home, simply tap on the icon with a picture of a house in the bottom left corner of the screen.
