What is this list?

Randomizers are hacks, mods and utilities that randomize video games in a way that significantly increase their replayability. Their randomization are applied before or when starting a new game in order to effectively generate many different games to experience based off the originals. They are also designed to prevent unwinnable states or introduce new potential softlocks as much as possible.

This list shows all randomizers known to me, regardless of their fun factor. They are listed by the games they randomize and grouped by game series, along with the randomizer's name in parentheses and additional documentation whenever necessary. I update the list frequently and try to keep it up-to-date to the best of my abilities.

In order to prevent the list from being polluted with randomizers that do not conform to the above definition, the following is not considered sufficient for inclusion:

The following rules are used to determine the game name showed in the list:

If you ever notice a video game randomizer valid for inclusion that is not already listed, please contact me so I can add it! Special thanks to the numerous contributors so far that have made this list what it is today!

You can look for the Randomizer tag on Twitch to easily find channels streaming live randomizer video content. In particular, the RandoMania channel almost exclusively streams such content, including speedrunning tournaments.

You can chat with other randomizer enthusiasts on the Randomizer Central Discord community.

For those interested in creating randomizers, you can listen to the Making a Randomizer panel from Awesome Games Done Quick 2019 explaining the process in detail. ROMHacking.net is also a great resource with plenty of technical information and tools for hacking video games in general.

For those that perfer an original game experience but still want to experience a randomized challenge, Retro Bravery and Hitman Roulette can generate interesting rulesets with randomized goals for many classic video games.

Honorable mention: The Nintendo 64 version of Resident Evil 2 contains an unlockable Randomizer mode. As far as I'm aware, it is the very first item randomizer in a video game.

Dishonorable mention: The Genesis version of Action 52 contains a Randomizer mode, but all it does is pick a game at random. As far as I'm aware, it is the earliest use of the term "Randomizer" in a video game.
