Roblox, stylized as RŌBLOX, is a 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 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 company's main source of revenue comes from players buying Robux, the main virtual currency in the game.
Players can customize their virtual characters with hundreds of different hats, head shapes, body shapes, clothing, and gear. Players may create their own articles of clothing, which allows for a more personalized in-game experience. However, selling player-created articles of clothing and collectible items require Builders Club, but non-premium players may still create T-shirts, which are decals attached to the front of a player's torso.
Players can add other people they meet in the game to their friends list. Since 2011, this can be done inside a game. On 4 February 2015, a new update to replace the Friends and Best Friends system, named Friends and Followers, was introduced. This allows more personal game play if wanted. This update also allows 200 Friends and infinite Followers. Players also have the option join community groups. After joining, players can then advertise their group, participate in group relations, and set their primary group. On the website and in game, users who are under 13 years old can only use specific words that are part of a whitelist maintained by the Roblox moderators. In contrast, users who are over 13 years old can use any word except words that are part of a blacklist.
Roblox Studio is the program users use to customize their places. It is a free program that comes with Roblox.
Players use Roblox Studio's built-in building system to construct places with bricks from varying colors and shapes. Players also are able to use user made plugins and tools to build. Players also have the ability to scroll through the ROBLOX Library and find free models and scripts. ROBLOX also created a "Official Model Maker" system where talented model makers are able to create and make their creations visible on the front page of the ROBLOX Library model section.
Players can use the programming language Lua to dynamically change the environment of the game. Also, plugins can be developed with Lua to be used in Roblox Studio. The exact version of Lua that is used in ROBLOX Studio is Lua 5.1.
Roblox was created by founder and co-founder David Baszucki and Erik Cassel in 2004 and officially launched into its beta version, titled Dynablocks in 2004. Soon, Dynablocks was renamed to Roblox in 2005 and the website was officially launched in 2006. It was named after a portmanteau of the words robots and blocks. Roblox is still in the beta stages today. In 2005, people could gain the currency at that time, Roblox Points, by completing single-player mini games developed by Roblox admins. As the game was released publicly in 2006, people came to the game slowly, but eventually the game started growing to its 6 million account base. In early 2006, Roblox had one currency, known as Roblox Points, first used like the Player Points, then as an upgrade to one's avatar, which was subsequently discontinued and replaced with "Robux". In mid-2007, Roblox added more customization to user characters to allow items such as caps to be worn. Roblox badges were first introduced on 22 December 2006. Meshes were added, and so were the abilities of sending friend requests to other players, and sending messages. Other things accomplished in 2006 were searching through players, places, and items, multiplayer places, stats, and inventories.
In 2007, character customization became possible. In late January, the abuse report queue was introduced, with the ability for any user to report content as inappropriate through the "Report Abuse" buttons disseminated throughout the site. In March 2007, Roblox became compliant with COPPA, with the addition of safe chat, a change which made users who indicated to be under the age of 13 at registration only able to communicate by selecting predefined messages from a menu. In August 2007, Roblox added Builders Club, a premium membership, and applied server improvements.
The safe chat feature was removed and was replaced by a system based on a whitelist for users under 13 years old and on a blacklist for other users. This new system allows users under the age of 13 to create content on the website, which they were not able to do previously. Any words that are not pre-approved will be replaced with a series of number signs (#). This has been subject to criticism, because perfectly fine words can be censored
Roblox can be played on many Android devices, as well as the iPad 2, the iPhone 4, the iPod touch 5th generation or any successor to one of those Apple devices. This is done with the Roblox application which can be obtained from the application store. The application allows purchasing items from the catalog that are not available for users not using the mobile application using the currency system of iTunes. The application can be used to view the user's inventory, friends, groups, and messages. It can also be used to purchase upgrades (premium memberships or Robux) with the currency system provided by iTunes and Google Play.
During the alpha period, only selected places such as Crossroads, Paintball!, ROBLOX Snowmobiling, Dodgeball!, etc. could be played from the application. The application is now stable and allows any place to be played. However, many places are not adapted to be played on the mobiles, which can result in games being too slow or some games being impossible to play because of the controls that are not available on mobile.
Roblox is free to play, although members may purchase monthly memberships to enhance their game experience. One membership option, Builders Club, grants players multiple amenities, including a daily virtual currency stipend of 15 Robux per day. Other membership options include Turbo Builders Club and Outrageous Builders Club, with each option getting more expensive than the last. Depending on the tier of Builders Club a player buys, the player can unlock more places to build in, more money to spend, more groups to join, and the ability to create and sell clothing. Recently, ROBLOX has given non-upgraded users a severe disadvantage which has been subject to criticism. In August of 2015, ROBLOX discontinues 6 month and lifetime Builders Club, Turbo Builders Club, and Outrageous Builders Club.
