Tickets, commonly referred to as "tix", are one of the two currencies used in ROBLOX, alongside Robux. Tickets are earned by players by visiting the site daily and having other users visit their place. Tickets can be spent on catalog items and on advertisements. Tickets and Robux are the building blocks of the ROBLOX economy.
All users earn 10 each day they log in; however, a BC member will also earn Robux. In the past, when the ambassador program was still running, you earned2 per link each day. Some users were making a lot of money through this by having lots of running links.
Each time a player enters a server of your place, you earn 1. However, if you have BC, you can make your place BC only, giving you 10 per visit instead. This could easily allow you to gain thousands of tickets if you create a popular place if you have BC.
RoblEX, commonly known as the Currency Exchange, is a feature which allows you to trade your tickets for Robux and vice versa. This, in turn, creates the ROBLOX economy as the price of tickets and Robux change through supply and demand. You can earn a substantial amount of money by buying a large amount of Robux for a lower price, then exchanging them later for a larger sum of tickets.
You can buy certain items using your tickets through the ROBLOX catalog, including hats, faces, and player-created content. You can also sell your own content, such as T-shirts, to earn revenue.
