- Main article: History of ROBLOX
In December 2003 to January 2004, Roblox was known as Dynablocks , but the name was changed to Roblox in the same year on January 30, 2004. Roblox alpha testing ended in February 2005 and beta testing began on the same year. In April 2006, Roblox was fully released to everyone with multiplayer games.
Roblox is available on Windows, Mac, iOS, Android, Xbox One and on the Windows Store. People interested in getting more involved with Roblox can make an account, but they can play as a guest. Users choose their own username and password, and can then create their own places. Users also have their own character, which can be customized via catalog purchases, and they can participate in social aspects of Roblox such as the forum, messages and friend requests.
- Main article: Place
Places are the most important thing on Roblox. They are created by users and can be played by other users. Players can create unlimited amount of places, but active places are limited to 200 places regardless of membership.
Before September 27, 2017, the amount of active places a player can have was based on one's Builders Club membership:
- Free users - 1 active place
- Former BC (players whose BC membership has expired) - 5 active places
- BC - 10 active places
- TBC - 25 active places
- OBC - 100 active places
Roblox provides templates for users which don't know how to start.
- Main article: Catalog
Roblox's Catalog is a place where users can buy items to customize their character. Free users are limited to free items released by Roblox and old not updated t-shirts released in 2007–2008 without costing any ROBUX. Roblox doesn't give a daily ROBUX reward to free users, as it did with tickets (Builders Club members get it) and doesn't provide clothing creators a way to sell their clothing for free.
Similar to the catalog, the library is used by users and developers to release models, scripts, audio, decals, meshes and plugins to other Roblox users. All items on the library that are available for purchase are free, and any user may take items to place in their inventory. You can have unlimited items from the library, and some groups place their models on the library to make it easier for them to be used in multiple games.
