Roblox is a multiplayer online game that was played on Surviving Mondays.
Roblox allows players to buy, sell, and create virtual items. Clothes can be bought by anyone but only players with a Builders Club membership can sell them. Only Roblox administrators can sell accessories, body parts, gear, and packages under the official Roblox user account. Items with a limited status can only be sold on the catalog or traded with Builders Club.
Robux is the virtual currency in Roblox that allows players to buy various items. Players can obtain Robux through real life purchases, another player buying their items, or from earning daily Robux with a membership.
