# Random Controller

*Part of the **Logic Controllers** category. Also documented in context in the [full Component Reference](/user-manual/component-reference/#random-controller).*

![Random Controller](/images/screenshots/logic-controller/random-controller.png)

The Random Logic Controller acts similarly to the Interleave Controller, except that
instead of going in order through its sub-controllers and samplers, it picks one
at random at each pass.

> **Note**
> Interactions between multiple controllers can yield complex behavior.
> This is particularly true of the Random Controller.  Experiment before you assume
> what results any given interaction will give
