This is a wiki for the free (with optional in-game purchases) multiplayer online flash game Idle Online Universe.


The role of the Wiki is to answer any questions players may have encountered in IOU, while giving all additional information that may be searched for. Users are encouraged to add missing information and fix mistakes in order to present the best source of information for other players.


Breaking of any policy can lead to a short term suppression; continuing to break policies may lead to a permanent ban. Users may be warned depending on the severity of the violation.


Large pictures that may include any form of artwork is recommended to either be watermarked, or agreed/accepted by the owner (Ray).

Free Content

All text written by users is available under the free content license within Wikia's Terms of Use. This means any information on the wiki can be copied and reused by anybody, under the terms of copyright laws. Credit to the authors must be given, usually in the form of a link to the original wiki page.


When in doubt about how to format something in an article, refer to Wikipedia's Manual of Style. Avoid squishing text in between images on both sides of the article.

Because this wiki uses a lot of tables, here are some recommendations to keep them readable in source mode: put the entire row on one line using double pipes when doing so would not take up multiple lines in the editor or hurt readability; use a single space as padding around cell values; keep inline styling to a minimum (site-wide styles can be added when necessary).


Images should be given a short but descriptive name and should always be categorized. Please make sure you are using "Best" quality in the game settings if taking screenshots to upload. Whenever possible, please reupload images that were updated in the game over the existing wiki image instead of as a new image. Images may be in multiple categories (e.g, Fishing images and Currency images) but should not be placed in redundant categories (e.g, an image of a fish should be placed only in Fish images, which is a subcategory of Fishing images). See Help:Categories for how to add categories and Category:Images for an overview of image categories on this wiki.
