How many guest accounts were in Roblox ever?

There is no publicly known exact total count of how many guest “accounts” existed in Roblox over the years. Roblox never released a number like “X million guests total,” and the guest system was designed so that each guest session was essentially a temporary, non-registered account, not a permanent entry in the user database like normal accounts.

Why the number is unknown

  • Guests were sessions, not classic accounts
    When you played as a Guest, you got a temporary ID (like “Guest 12345”) that was generated for that session. These were not full user accounts with long- term data, and they weren’t tracked in the same way as registered accounts.
  • No official total was announced
    Roblox’s official announcements about removing guests in 2017 mention the feature’s history and reasons for removal, but never a cumulative total of how many guests had ever played.
  • Scale of Roblox makes a single number impractical
    With billions of registered accounts now and tens (possibly hundreds) of millions of play sessions over more than a decade, the guest system likely saw hundreds of millions , maybe even over a billion , guest sessions in total, but that is speculation based on scale, not an official figure.

What we know for sure

  • Guests were introduced: September 26, 2008.
  • Guests were removed on PC: October 2, 2017.
  • Limited mobile/exploit access continued: Some players could still play as guests on mobile or via exploits until most of those were patched by November 24, 2018.
  • Guest appearance was tied to the “Roblox” account: Originally, if the official Roblox account changed its avatar, all guests would reflect that change, so special accounts (DefaultGuest, BillyBloxxer, BettyBloxxer) were created to define a fixed guest look.

Reasonable estimate (not official)

Because Roblox never published a total, any number is an estimate:

  • If we assume:

    • Millions of daily visits over ~9 years of active guest support (2008–2017),

    • And a significant portion of those visits were by unregistered users playing as guests, Then a very rough ballpark could be:

    • Hundreds of millions to possibly over a billion guest sessions in total.

But this is not a confirmed number ; it’s just a logical guess based on Roblox’s massive size.

Short answer:
Roblox never published how many guest accounts (or guest sessions) there were ever. The exact number is unknown, though over the system’s 2008–2017 lifetime it likely ran into hundreds of millions, possibly more than a billion , guest plays overall.
