The Dice extension adds the ability to automatically substitute random dice when an edit is saved, and logs the dice being rolled to a special page.

When an edit is saved, requests for dice rolls in the form @@xdy cause dice to be "rolled" and logged, and are substituted with a tag that displays the result.

Roll results are intended to be tamper-proof, and easily verifiable. The extension provides a special page where dice roll logs can be examined.


Provides a magic keyword that is substituted when a page is saved with the appropriate <dice> tag to display the result of a roll. The dice tag can be moved around, but remains attached to a log entry and will resist modification of the result.

Dice roll keywords are "standard" roll specifications prefixed with @@; specific accepted formats are as below:

Formula Description Example
@@[x]dy roll x (default 1) y-sided dice @@3d6 to roll 3 6-sided dice
@@[x]dybn roll x (default 1) y-sided dice, keeping the best n @@3d6b2 to roll 3 6-sided dice, keeping the best 2


  1. From your $IP/extensions/ directory, check out the Dice extension with
    git clone https://www.uberbox.org/git/Dice.git
  2. Add the following line to the bottom of LocalSettings.php (though not after trailing ?>, if it is present):
  3. This extension adds a table to the database to hold the results of dice rolls, so you need to run the update script (instructions).
  4. Installation can now be verified through Special:Version of your wiki.

User rights[edit]

rolldice: user can roll dice by saving a page with the magic keyword, and can use the Special:Dice special page to check their roll history. checkrolls: user can use Special:Dice to check the history of rolls of users other than themselves.

E.g., if you want everyone to be able to roll dice and check rolls:

$wgGroupPermissions['*']['rolldice']    = true;
$wgGroupPermissions['*']['checkrolls']    = true;
