We recently added further detail to our UGC guidelines in our Terms of Use to help set clear expectations for what users are paying for when it comes to virtual items. Under our Terms of Use, developers must indicate the actual numerical odds (such as a 30% chance) of what users may receive when they are buying a random virtual item in-game using Robux or other currency. We’ve provided more detail and examples below to help make these guidelines clear.

Please note that you are required to disclose those odds whether the user pays directly for a virtual item or indirectly. Here is an example of a user paying indirectly: Your game allows a user to receive a virtual coin in exchange for Robux; the user then goes to a different place in the game and throws the coin into a fountain, and receives a random virtual item. In this example, developers must disclose the odds of receiving each type of random item before the user throws the virtual coin into the fountain.

In-Game examples or included probability:

If your game includes mechanics where a virtual reward is provided in exchange for completing an action that does not involve the payment of Robux or other currency, then you do not need to state the odds of receiving that reward. For example, if you successfully battle against a monster and get a virtual reward for your efforts then you do not need to state the odds of receiving the reward.

Please ensure your games adhere to these guidelines by August 8, 2019. If you do not comply within that time period, you run the risk of your game being moderated (for more information on the Roblox moderation system, see: https://en.help.roblox.com/hc/en-us/articles/360020870412-Understanding-Moderation-Messages).
