To change the player slots of a Core Keeper server on PlayNHost, click Edit slots on the Active players card on the server's Overview page, choose a number and click Update. The server restarts so the game uses the new limit, and everyone on it is disconnected.
How do I change the slots?
- Open your server in the panel. You land on Overview.
- On the Active players card, click Edit slots. You can also click the pencil on the Slots row of the server card on the same page. If you see neither, your role lacks the Rename server permission.
- In the Edit Player Slots window, choose the number. The window says how many players your plan allows.
- Click Update. The server restarts with the new limit.

The restart disconnects everyone on the server. Do it when nobody is playing.
