Idle Online Universe Wiki


The Settings menu is a page to modify the player's experience of the game. Settings can be accessed by clicking on the 'gear' icon in the top right. Settings are divided into several pages. Hover over an option in the game to see an explanation.

Old Icon


These options affect playing in a Party.


Join Settings[]

Allowing open join allows players to join you in a party, unless the party you are in is full or this option is set to OFF. You have to enter a join password, otherwise disabling this option won't affect anything. You can also set this specifically for members of your Guild.

Creating a password will force somebody attempting to join to enter in the correct password before being able to join the party. It is recommended to have a password if you are either farming with a permanent party or do not want others to join in.


These options affect various visual effects; turning some off can improve performance.



You can cap the number of frames per second the game processes.


AFK Mode.png

Turning on AFK Mode allows the game to display a very simple screen when you haven't interacted with it in a specified period of time. This can drastically reduce the system resources used by the game. You can then click the X button to return to the game at any time. Here you can set how many minutes the game waits to activate AFK Mode, and how many frames the game processes per second while AFK.

Floating Text[]

Here you can turn on or off various numbers that pop out and disappear while playing the game.

For "show when focused", if this is set off, then damage numbers will always be shown. If it is set on, then damage numbers will only be shown when the game has browser focus.
