Roblox is meant for all ages, but 10 to 18 is what I would say is the best. (besides counting those famous Roblox developers, those are ages 18 to 26.) Roblox alone is a really good game, which others can express their minds on creating and building, with unlimited imagination. Roblox has no swear words, but sadly, some other players think otherwise to that. Other adult reviews are making reviews about other players being older and try to get past the filter system saying profanity, or even hacking the chat system. This has NOTHING to do with Roblox, but I would say ROBLOX needs to actually be more strict with them instead of not reading report reviews most of the time.If a parent is reading this, PLEASE tell you child the following: 1. do NOT give any private information, including the least concern, which is age. 2. do NOT fall for the "free robux" scams, as this will take any robux on your account, or even take your account itself. (if this happens, contact Roblox immediately. even put a parent's email after or before you get scammed, just for proof that it is your parent contacting Roblox if happens in the future.) 3. leave games quickly if something looks odd in the game such as deleted parts, different images, etc. this means the game got hacked by a hacker, or maybe the hacker is still even in the game. 4. make good decisions, do not play role playing games with strangers. those strangers may be hackers or may be above 18 years of age. play with only their good, loyal friends. 5. strangers online come together to make friends with others. they can play games with them, or become friends with them, but just know if they seem fishy, avoid them. ROBLOX does ban players that don't follow the terms of services, so don't worry about that. If one sees another doing something inappropriate or whatnot, you can even report them, but this is optional. As always, STAY SAFE! -2012 Roblox Player, EpicThunder231.
