Have you ever wondered what the most rare badge on Roblox is? Or which is harder to get: the Bloxxer Badge or the Bricksmith? I was wondering the same thing myself on Friday and I found some interesting numbers out of our database. I put together this table (data from February 16th):
What does this show? Well first, the Count column tells us how many accounts have earned a particular badge. For example, we can see that, as of Friday, there are 103 Bloxxers on Roblox, but only 25 Bricksmiths. This means it is roughly 4 times harder to get a Bricksmith badge than a Bloxxer. Even more interesting is that almost no one has earned the Inviter badge – it is the rarest badge on Roblox. There are more Admin badges out there than Inviters!
Since Roblox now has more than 15,000 users, and only a fraction of those have been playing since we have added badges, in order to get a feel for the distribution of different badges amongest active players, I also computed the prevalence of each badge. This figure it relative to the number of players who have earned any badge. For example, of all the people who have any badge, 9 in 10 of them have a Combat Initiation Badge – by far the easiest badge to get.
