What is Roblox? Roblox is an online virtual playground and workshop, where kids of all ages can safely interact, create, have fun, and learn. It’s unique in that practically everything on Roblox is designed and constructed by members of the community. Roblox is designed for 8 to 18-year-olds, but it is open to people of all ages. By participating and by building cool stuff, Roblox members can earn specialty badges as well as Roblox currency called robux/premium currency. They can use robux/premium currency to shop at the online catalog to purchase avatar clothing and accessories
