# Run a sim

Updated Oct 2026

## Set up the sim

A sim runs on a character from your list. If yours isn't there, [add it first](https://www.noxxic.com/docs/add-a-character).

1. Open your character's page and choose **New sim**.
2. Pick the sim you want from the list.
3. Under **Choose a mode**, pick the fight to sim.
4. Under **Choose a rotation**, pick the rotation you play with.
5. To sim another spec of your class, pick it under **Choose a spec**, where the sim offers it.
6. Where the page asks you to **Paste your SimC addon string**, [export your character](https://www.noxxic.com/docs/simc-addon) and paste it.
7. Choose **Start sim**.

[Sim modes](https://www.noxxic.com/docs/sim-modes) explains which fight to pick, and [Rotation styles](https://www.noxxic.com/wow/info/sim-with-one-button-assisted-highlight) what each rotation plays. A sim with a crown beside it is part of [Premium](https://www.noxxic.com/premium).

## Start on your rotation

The setup page and **Create guide** start on Standard. To start them on the rotation you play with:

1. Choose your name at the foot of the sidebar, or **Account** at the foot of the page on a phone.
2. Under **General**, set **Rotation**.

A rotation you pick on the setup page still wins for that sim. A sim you start from a ranking or a class guide plays that page's rotation.

## While it runs

The page shows each part of the sim and how far it has to go. Choose **Cancel** to stop it.

You can close the page. The sim carries on, and its report opens there when it finishes. It's also listed under **Sims** on your character's page. [Read a sim report](https://www.noxxic.com/docs/read-a-sim-report) explains what it shows.
