The level to which a game provides new challenges, learning opportunities, or experiences when played again.
This pattern is a still a stub.
Many games are designed to be played many times. In order for these to be interesting, the game must offer new challenges to players or give players new experiences that are perceived as entertaining enough to merit continued playing. The degree to which a game provides these incentives determines its level of Replayability.

Example: Chess and Go have so many possible outcomes that players have very little chance of ever playing two games that are exactly the same. This means that every game session will have new challenges in which players can test their skills.
Example: The multiplayer first-person shooters Team Fortress Classic and Return to Castle Wolfenstein and the Battlefield series allow players to choose a character class to play. This gives them special abilities, which means that beyond the normal differences in gameplay due to varieties in players and levels, players also have different possibilities of what to do and have different roles in their teams.

Using the pattern
Replayability can be achieved in several different ways: by letting the challenges players met differ between game instances, by allowing the challenges be solved in several different ways, or by letting players compare results between different game instance through Trans-Game Information. Besides these strategies, Save-Load Cycles and Reversability provide local Replayability within games and allow players to do Experimenting, but they have little effect, or negative effect, on Replayability of the game as a whole.
Games that provide a huge potential game state space seldom offer players exactly the same challenges and thereby provide one form of Replayability. Another is to use Randomness. All but the most trivial uses of Randomness make gameplay challenges different, but this can become more explicit when it is used to create different Ephemeral Goals, Quests, Levels, or Game Worlds for every game instance (as for example is done in NetHack and Minecraft). A slightly more limited version is to use Asymmetric Starting Conditions or Asymmetric Goals (as for example Memoir '44 or team versus team matches in the Left 4 Dead series), but this can be use together with other solutions to multiply the variety of challenged encountered. Dedicated Game Facilitators that are aware of players who have played the game before can change the setup of the particular game instances to provide new challenges. This can for example be achieved through Reconfigurable Game World, although games with Player Constructed Worlds can allow the players to reconfigure their Game Worlds without the presence of Dedicated Game Facilitators (Settlers of Catan provides an example of this).
While differing the challenges in the ways mentioned above given Varied Gameplay, this can also be achieved through letting players have different ways of trying to meet the challenges. Asymmetric Abilities is an easy way support this but letting players complete the game or parts of the game in different ways can be done through providing them with Selectable Sets of Goals. Optional Goals and Sidequests can provide some varieties as well since players can try to either try and complete different set of them, or all or none of them, compared to earlier game instances. Easter Eggs can offer the same type of options for players, as long as they are aware of them (e.g. through linking Achievements to them). Functional Roles in Multiplayer Games lets players try to solve different types of subchallenges to the overall challenges and therefore can provide Replayability as long as players are willing to change roles between game instances or game sessions.
Replayability is often acquired by supporting players with Trans-Game Information to measure their level of successes with previous game instances, which can be their own or other players. For games that require player skill, Replayability becomes automatic as players strive to achieve, test, and show Game Mastery. Similarly, games where players can make use of Strategic Knowledge have a certain level of Replayability, as players can develop this knowledge between game session to improve their gameplay.
Scores and High Score Lists can be used as a measure of Game Mastery in both Single-Player and Multiplayer Games, and allow the players to have a measure of their Game Mastery. Speed Runs, formalized to be measured by the game system (as Portal's or Cogs time challenges do) or improvised by players, can perform the same function. Tournaments, with the exception of Polyathlons, also allow for a similar type of Replayability as a game is typically played several times to create the outcome of the Tournaments. Near Miss Indicators can show players how close they were to succeeding, encouraging them to try again and possibility also increasing their chances of succeeding by the information the provide.

Achievements can explicitly encouraged Replayability present through other patterns, for example to make players make use of different Abilities or choosing different goals from Selectable Set of Goals; Testing Achievements are in particular worth mentioning here since they can encourage players to first test different ways of playing before committing to them.
Unwinnable Games do not in themselves provide Replayability but they are often designed to function as such, so this type of game may be considered if Replayability is a high level design goal.
Games that are challenging or provide experiences based upon the lack of knowledge of players, i. e., Imperfect Information, are difficult to combine with Replayability. This is due to the Trans-Game Information players acquire when they successfully perform Memorizing of what happens in the game, i. e., when they can apply specific facts learned in one game instance in another game instance. This information can affect Replayability in many ways: Surprises in Narrative Structures will no longer be Surprises, Tension will be less effective when players experience the same situations, Puzzle Solving will become trivial if it is not changed between game instances, Unknown Goals will be known in later game instances, and Exploration will be pointless since the environment is already known to the player. An exception to this is presented by Conceal goals in Multiplayer Games, as the challenges in these are to find new hiding places.

Replayability in a game offers players enjoyment of a game beyond a single game session, and often does this through offering Varied Gameplay between game sessions. When this is due to player being able to contemplate different ways of playing, this leads to Stimulated Planning.
Although developing Strategic Knowledge can be part of why a game has Replayability, having complete Strategic Knowledge can work against the pattern instead. Examples of how can happen is fully understanding Algorithmic Agents without Open Destiny or being able to Memorize all choices that are supposed to require Puzzle Solving.
