 [[Encouraged Return Visits]] assumed that there is a game to return to and that it is possible to join and leave it often, so a requirement for this design choice is that the game in consideration already supports [[Drop-In/Drop-Out]] gameplay, and typically this is done through a [[Persistent Game Worlds|Persistent Game World]]. Partly because they often have such [[Game Worlds]] and partly because they want to have a certain number of players at all times, the pattern is commonly used in [[Massively Single-Player Online Games]] and [[Massively Multiplayer Online Games]]
-There are several different ways of encouraging players to return to games. The simplest is to give [[Rewards]] to players for returning at certain intervals, e.g. giving one reward every. This can be modulated by using [[Higher-Level Closures as Gameplay Progresses]] - that is increasing the [[Rewards]] for consecutive visit, which for example [[FarmVille]], [[Ravenwood Fair]], and [[Zombie Lane]] does. [[Delayed Effects]] or [[Development Time]] are probably the easiest, simply making the period before the effect takes place long enough forces players to leave the game for real world reasons but they still need to return to see the effect. Planting and harvesting crops in [[FarmVille]] is an example how this can be used in games. [[Budgeted Action Points]] combined with [[Regenerating Resources]] is another basic solution, used for example in [[CityVille]], [[Ravenwood Fair]], and [[Zombie Lane]], that can easily be combined with [[Extended Actions]]. These may be [[Interruptible Actions]] but this adds a [[Risk/Reward]] component to departing the game - in fact, [[Encouraged Return Visits]] can be seen as a way of making [[Continuous Goals]] have more [[Challenging Gameplay]] when the actions can be interrupted. [[Investments]] is a more specific way of achieving actions with [[Delayed Effects]] while [[Collecting]] is an activity that can support [[Encouraged Return Visits]] because the [[Resources]] are not always available and appear at [[Spawn Points]] or other types of [[Resource Generators]]. Making players [[Always Vulnerable]] to attacks from [[Enemies]] and other players, as for example is done in [[Eve Online]] and [[Travian]], also encourages players to return often to notice if such attacks are occurring or are being prepared. [[Asynchronous Collaborative Actions]] ties [[Encouraged Return Visits]] to [[Cooperation]] with the possibility of [[Guilting]].

 Having [[Events Timed to the Real World]] is another option for [[Encouraged Return Visits]] since players need to wait for the real world event to happen before they can perform certain actions and complete certain goals in the game world. While [[Events Timed to the Real World]] give rise to specific [[Ephemeral Events]], these in general can used also to create [[Encouraged Return Visits]] as long as players can become aware of them, e.g. through [[Extra-Game Broadcasting]]. These events are a form of [[Extra-Game Input]] when they are added to the gameplay during ongoing games, e.g. as the soccer-inspired missions were added to [[Mafia Wars]]. [[Extra-Game Broadcasting]] can also be used to remind players of their own actions that need doing and thereby strength how they provide [[Encouraged Return Visits]], but [[Extra-Game Broadcasting]] of other players' actions can in itself encourage players to return to the game by simply reminding them of its existance.

 [[Persistent Game Worlds]] add two other options. First, if they have [[Evolving Rule Sets]] due to designers often adding or modifying parts of the game, players will need to return regularly to keep up with the changes in the game or be disadvantaged. Second, if actions and events have long enough [[Delayed Effects]] it may not be possible to notice these effects during one play session. Third, if they support [[Altruistic Actions]] or other reasons for [[Delayed Reciprocity]], players may both want to return to see if others have return the favors they have given, or feel that they might now owe other players to help them. The two latter can also be used in games with [[Drop-In/Drop-Out]] gameplay as long as game instances last long enough to make return visits meaningful to consider.

-Games where ''players'' need to visit specific real world places, i.e. those with [[Player-Location Proximity]], are likely to create [[Encouraged Return Visits]] since they are unlikely to be possible to complete if the gaming area is big enough.

+''Game structures making players want to return to certain places or activities in the game over several game sessions.''
 Some games are created so they cannot be finished in one play session. This of course risks that players never return even if they are playing with or against other players. To make the players of these games return they can be designed to have [[Encouraged Return Visits]], i.e. as part of their gameplay players do plan when they should play again.

 Persistent game worlds such as [[World of Warcraft]] can have certain quests and items only available at times matching certain dates in the real world (e.g. ''New Year's Eve'', ''Oktoberfest'', and the ''Day of the Dead''), encouraging players to at least play then. [[Mafia Wars]] did a similar thing in having a special challenge mission related to the world championship in [[Soccer]] 2010.
