Passes, formerly and most-commonly known as game passes, are items that users can buy directly from an experience's page, and if the developer of the experience prompts a visitor to buy one. Passes are used similarly to the early-era VIP t-shirts in that they are used to grant special features and items in the experience they are marketed for. Plus, because they are linked to the experience's page itself, the risks of scamming are minimized which is why passes have long since replaced VIP t-shirts.
Passes were added in September 2012. Shortly after its release, a blog post was made to give users information on them.
Unlike VIP t-shirts, passes allow users (even those without Premium) to offer exclusive in-experience features without requiring the user who purchased it to wear a specific t-shirt. In addition, as an anti-fraud measure, revenue generated from passes is temporarily withheld from the creator. Making a pass initially, cost a 100 Robux fee. This fee has since been removed, and making a game pass is now free.
