Roblox had about 11,253 users in 2006 , based on a year-by-year user milestone list that shows 155 test users and 11,408 contest users for that year.

Quick Scoop

  • 2006 was still early Roblox.
  • The platform was much smaller than it is today.
  • Depending on whether you mean registered users or active players , the number can look different.

A separate source says Roblox had around 1 million registered users during 2006 and about 5 million by the end of that year , but that estimate conflicts with the milestone list above, so the safer answer is to treat 2006 as a very small early-user period.

Short version

If you mean how many people were on Roblox in 2006 , the clearest sourced figure here is 11,253 users joined that year.

TL;DR

Roblox in 2006 was tiny compared with now: roughly 11k new users by one milestone count , with some sources describing it as around 1 million registered users by that year’s general timeline.
