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.
With only twenty days between the end of the Christmas 2012 Event and the start of the Valentine's Day Event, it was one of the shortest gaps in-between two major updates. At the end of the Christmas Event, however, the snow which covered the player's Springfield at the start of it did not disappear, and instead vanished at the release of the Valentine's Day Event. In the gap between the two events, there was much speculation as to when the snow would disappear.
