Another new social feature became available for players during the event. They could visit their friends' Springfields and leave Valentine's Cards by tapping on their buildings. When they logged into their game, they would be able to tap the character who is unlocked with the building and collect a Heart. Only buildings which unlocked characters upon completion could have Valentine's Cards delivered there, as when the friend logs in, the card appeared on characters which the building unlocks, and not the chosen building.
