If the game creator has enabled VIP Servers on their game, you can use Robux to purchase a Private Server that you can enjoy with a handful of your friends without anyone else interrupting.
How much do private servers cost?
Private Server prices are set by the game's developer. This will be charged when you initially make the purchase and will be charged again every month to keep it active. The monthly renewal fee will be taken out of your Robux balance automatically, so you don't need to worry about forgetting to renew every month.
How do I create one?
When viewing a game's details page, click on the Servers tab. If this VIP feature has been turned on, you will see a section entitled VIP Servers. This is where you can find any private servers that you have created or are a part of. If you see any, you can go ahead and play right away! If you would like to create a new one, this can be done by clicking the blue Create VIP Server button.
When you have chosen to create a new server, you should see a box that looks like the below picture. You will give your new server a custom name and go over the subscription agreement. Once you have read over all of the information on the box and chosen the perfect name, you can finish the process up by clicking Buy Now.
After completing your purchase, you will can choose to view your server configuration screen or not.
On the server configuration screen, you can rename the server and invite specific users to participate by entering their usernames into the appropriate box and clicking Add. You can invite up to 50 individual users, or you can allow everyone in your friends list to join by checking the Friends Allowed box.
This page also includes a feature to generate a link that you can use to directly access your specific server. To do so, click the blue Generate button. Once you have configured everything as you desire, you can click Save to start using it!
Once everything has been set up, your new purchase should now appear in the Private Servers section of the game details page. To play, simply click on the Join button. If you would like to make any further edits, click on the menu button (looks like three dots) in the upper right corner of the server's box and select Configure.
How do I cancel my server from renewing or make it temporarily inactive?
If you would like to prevent your server from renewing at the end of the month, this can be done at any time before its renewal date. To do so, configure your purchase by clicking the Menu button (looks like three dots) to the far right of its entry in the Private Servers section of the game's details page and then clink Configure.
To cancel your monthly charge, click the green Active icon next to Subscription Status. You will need to click Cancel Payments on the confirmation window for the subscription to be cancelled. You will still get to use your server for the remainder of the month that you have already paid for, but it will expire at the end of this time.
To temporarily make the server inactive for a period of time, click the green Active icon next to VIP Server Status. You will need to click Disable on the confirmation window for the server to be deactivated. You can click it again to reactivate it at any time. However, it is important to keep in mind that your renewal time will not be extended for this period of inactivity and will still renew or expire on the originally scheduled date.
What happens if I don't have enough Robux on the renewal date?
If this happens, then the server will expire and will no longer be able to be used, but it can be repurchased at any time.
How can I enable VIP/Private Servers on my own games?
If you are a developer and would like to add this feature to your game, you can do so in your game's configuration page. More information on this page as well on instructions on how to find it can be found in this help article.
Once you are in your game's configuration screen, navigate to the Access tab. There you can check the box that says Allow VIP Servers, set a price for your server, and click the Save button. For every server purchased, Builders Club users will receive 70% of the price set while Non-Builders Club members will receive 10%.
It is also important to keep in mind that Private Servers are only supported on a individual place basis. If your game/universe uses multiple places and you want to allow VIP servers, it is recommended to allow VIP Servers on the game's lobby/starting place.
