Description

This is the BIGGEST roller coaster group in all of roblox! (RCB for short) For those who love building roller coasters and for the roller coaster lovers! Get people to join and you will get ranked up to RCB Inviter rank. If you want to become a roller coaster builder then pm our RCB Coaster/Waterslide Tester. He will test your ride and determine if your ride is fully functional. If you want to spend your own robux/tix for RCB ads then pm me and I will put you as a RCB Advertiser. This group reached the top of the ladder in just one year. The second biggest coaster group took about 2 years to reach the top. So thanks to all people who helped us get to the top. This group was orignally founded by me but I didn't have BC so a nice man named belkin45g made it for me. He is now permanently banned and nobody knows why. After belkin45g, a person named bourlo took over. Bourlo ended up selling it to manone999 who later gave me RCB when I finally got BC. Ever since then RCB has been going great

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
