Yume Wiki is a collaborative effort by the members of the Yume Nikki Online Project, an open-source site that allows users to play Yume Nikki and some of its fangames online, powered by EasyRPG. YNOproject enhances the game experience with live chat, map information, exploration parties, achievements, expeditions, and guided tours.
Among other purposes, this wiki helps provide important map information for players as they explore the dream worlds. Much of its content was originally forked from wikis hosted on Fandom.
Discussion about the project and the wiki can generally be found on the YNOproject Discord server. Anyone is welcome to play, chat, and contribute!
