Roblox, stylized as RŌBLOX, is an massively multiplayer online game created and marketed toward children and teenagers aged 8-18. In the game, players are able to create their own virtual world, in which they or other online members may enter and socialize within the blocks of varying shapes, sizes, and colors. Games on Roblox can be scripted using a sandboxed edition of Lua 5.1, to affect events that occur in-game and create different scenarios. The game has been known to be quite educational as children will learn computer programming, stocks, ratios, the advertising world and marketing throughout their choices of what they would like the do on Roblox. The company's main source of revenue comes from the "Builder's Club" virtual benefits, in which users who have created an account may purchase either Builders Club, Turbo Builder's Club, or Outrageous Builder's Club, otherwise known by users as BC, TBC, and OBC, respectively.
