ROBUX (singular ROBUK, plural ROBUX) or ROBUCK, stylized as R$, is the sole currency on ROBLOX. Introduced on May 14, 2007, ROBUX is known as ROBLOX's primary currency by the community and staff; all ROBLOX-created items within the catalog are sold in ROBUX.
Before ROBUX, ROBLOX points existed, which you would get for playing mini games, which came before user-created games.
Through premium membership
ROBLOXians who purchase a premium membership receive a daily ROBUX allowance. Users in a Builders Club membership earn 15 ROBUX, while those in Turbo Builders Club or Outrageous Builders Club earn 35 and 60 ROBUX respectively. Players also receive a 100 ROBUX bonus for the first-time purchase of a premium membership.A loyalty program was introduced as an incentive for users to continue purchasing Builders Club. With this program, players could earn up to 300% of their principal income, or up to 45, 105, or 180 ROBUX. A later update to the loyalty program reduced the amount a person can earn to up to 20% of their principal income (3, 7, or 12 ROBUX) and completely removed any loyalty bonuses for new Builders Club members. The program was discontinued in 2014.
ROBLOX released the ability to purchase ROBUX through their website on September 26, 2008. The guest feature was released on the same day.  The ability to purchase ROBUX through the ROBLOX Mobile App was released on December 11, 2012. ROBUX can also be purchased through a ROBLOX Card. ROBLOX Cards can be purchased at many 7-Eleven, GameStop, Walmart, Toys R Us, f.y.e, Target, Best Buy, CVS/Pharmacy, Future Shop, and Sainsbury's stores in the USA, Canada and England. Users with an active premium membership will receive an additional ROBUX bonus if they purchase ROBUX. Users who do not own a credit card can use Rixty, which allows them to purchase gift cards and use CoinStar machines to change the spare change into ROBUX. At the moment, Rixty does not work outside of the US.
With the November 2008 release of the RoblEX currency exchange, ROBLOXians are given the ability to exchange Tickets into ROBUX and vise-versa. The RoblEX's exchange rate is based off user demand and typically hovers around 1 for about 20 for market orders. However, on April 14, 2016, the currency exchange was shut down following the removal of tickets, the secondary currency.
- Main article: DevEx
The Developer's Exchange (DevEx) was released on October 1, 2013. This feature allows developers who meet specific qualifications to exchange ROBUX into real-life currency (USD) on a monthly basis. In order to qualify for DevEx, users must be currently enrolled in Outrageous Builders Club, have earned over 100,000, have a valid PayPal account, and be a verified account. Currently, developers earn $200 per 100,000 exchanged through DevEx.
The value of ROBUX has increased since its initial release. With 3,297, a ROBLOX Blog article declared Miked as one of the wealthiest ROBLOX players. Today, many users have upwards of 40,000 in their accounts without being considered by the community as wealthy.
Current theories about the dramatic shift in ROBUX value are embedded in the idea of supply and demand. Supply and demand are typically inversely related, and the balance of both establish the equilibrium price.
- As more users log into ROBLOX, ticket supply increases. This increase in supply creates a surplus of tickets, which therefore lowers the value of them. As a result, the ticket to ROBUK ratio increases (more tickets are required to "purchase" one ROBUX through the currency exchange).
- By selling most of their items in the catalog for ROBUX and incentivizing users to exchange ROBUX for real-life currency through the Developer's Exchange, the demand for ROBUX has increased. This increase in demand compared to a minimal increase in the supply of ROBUX creates a shortage of ROBUX. As a result, the ticket to ROBUX ratio increases.
According to the Developer's Exchange, 400 is equal to $1, while a 2013 blog post announced that one ROBUX equal to one penny.
- For 100, users in a premium membership can create groups. For the same amount of money, a player can upload a piece of audio into a game.
- For 1,000, users can change their name.
- Users can upload thumbnails for their places. An image thumbnail requires 20, while a video thumbnail requires 500.
- Players can purchase items in the catalog for varying amounts of ROBUX.
- Many users have created tutorial videos about how to get free ROBUX without being hacked or terminated. However this is not possible, as the ROBLOX administrators have stated there is no way to get free ROBUX. Some users have also created ROBUX generators which would grant players free ROBUX.
