Save files which consist only of a password.

Many computer games make use of save files. Password Save Files are the ones that are small enough to only need a password instead of actual data files.

Wikipedia and TV Tropes have entries related to Password Save Files named Password[1] and Password Save[2] respectively.


Examples of games using Password Save Files include The Lost Vikings, the first Populous, and the first game in the Prince of Persia series and in the Lemmings series.

Using the pattern

Designing Password Save Files lies primarily in designing how the passwords are generated. This is typically through simply naming them but they can also be generated based on the current game state, something which typically is needed for game states more complicated than those that simply are which Level one has access to.

Providing players with Password Save Files is typically done as they reach Save Points, most often ones between Levels.


Password Save Files are simply a form of Save Files possible when only very small game state (or very small parts of a game state) needs to be saved. Due to this, they do not actually need to have technical support for loading and saving, only for players to be able to input them to the game. Also for this reason, players can even more easily than for other Save Files engage in Game Element Trading with them.
