On November 24, 2015, Roblox introduced a new shadows for Humanoids that made players' shadow look realistic.<ref>{{cite web|url=http://blog.roblox.com/2015/11/new-shadows-bring-more-realistic-effects-to-humanoids/|title=New Shadows for Humanoids|author=arsenyk|publisher=Roblox|date=November 24, 2015|accessdate=November 24, 2015}}</ref>
== Gameplay ==
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.

=== Social interaction ===
Players can add other people they meet in the game to their friends list. Since 2011, this can be done inside a game.<ref>

=== World construction ===
[[File:Roblox Studio 2013 Editing Screenshot.jpg|thumb|Editing using Roblox Studio 2013.]]
Players construct games with building bricks or blocks that vary in size, shape, and color using Roblox Studio, a program used for customizing places. Players can use the programming language [[Lua (programming language)|Lua]] to dynamically change the environment of the game.<ref>{{cite news|url=http://kidslike.info/roblox_using_roblox_as_an_educational_programming_language |title=Roblox as an educational program language|publisher=Kids Like|accessdate=24 January 2009|date = 9 December 2008}}</ref> Also, plugins can be developed with Lua to be used in Roblox Studio.<ref>{{cite news|url=http://www.makeuseof.com/tag/roblox-lego-meets-webkinz-equals-fun-games/|title=Roblox - A Cool Lego-Based Free Virtual World for Kids|publisher=makeuseof.com|accessdate=11 October 2009|date = 29 June 2009|last = McDowell|first = Guy}}</ref> Roblox Studio was at February 2013<ref>{{cite news|url=http://blog.roblox.com/2013/02/introducing-roblox-studio-2013/ |title=Introducing ROBLOX Studio 2013|publisher=ROBLOX Blog|accessdate=2 February 2013|date = 2 February 2013}}</ref> replaced with its successor, Roblox Studio 2013. The second version of Studio features a more organized layout, [[static code analysis]], and a new design. Players were initially having problems with the screen shaking, the inability to select parts, and crashes during the first few weeks of the release which was fixed eventually.<ref>{{cite web|last1=Shedletsky|first1=John|title=ROBLOX Studio 2013 Fixes and Improvements Coming Soon|url=http://blog.roblox.com/2013/02/roblox-studio-2013-fixes-and-improvements-coming-soon/|website=http://blog.roblox.com/|publisher=ROBLOX Corportation|accessdate=6 March 2015}}</ref>
=== Economy and currency ===
Roblox includes two [[virtual economy|virtual currencies]]: tickets and Robux. They can be converted from one to the other with the currency exchange.<ref>{{cite news|url=http://blog.roblox.com/2008/11/its-the-economy/|title=It’s the Economy…|accessdate=19 July 2010|date = 21 November 2008|last = Shedletsky|first = John|publisher = Roblox Corporation}}</ref><ref>{{cite news|url=http://www.forbes.com/sites/alexknapp/2012/01/30/roblox-lets-kids-build-their-own-worlds-online/|title=Roblox Lets Kids Build Their Own Worlds Online|publisher=[[Forbes]]|accessdate=23 February 2012|last = Knapp|first = Alex|date = 30 January 2012}}</ref> Tickets are earned for a variety of activities, such as when places are visited, as a daily login bonus, or for item sales including clothing. In-game items can be sold for either a set price in any type of currency, allowing the buyer to choose which currency they pay with. Robux is earned daily by premium members in varying amounts depending on the user's type of membership. Robux can also be earned through sale of virtual goods or can be purchased directly with money.
===DevEx===
The developer exchange, widely known in the game as ''DevEx'', is a feature that exchanges the game currency, ''Robux,'' to real cash. This option is only available to users that hold ''Outrageous Builders Club'' and at least 100,000 Robux. Users of the developer exchange can make from $250 USD (100,000 Robux) to $20,000 USD (eight million Robux) in a month.
===Mobile gameplay===
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.<ref name="ROBLOX Corporation">{{cite web|last1=Haak|first1=Andrew|title=Video: Testing Popular ROBLOX Games on the iPad|url=http://blog.roblox.com/2012/10/video-testing-popular-roblox-games-on-the-ipad/|website=http://blog.roblox.com/|publisher=ROBLOX Corporation|accessdate=6 March 2015}}</ref><ref>{{cite web|last1=Haak|first1=Andrew|title=ROBLOX Arrives on Android|url=http://blog.roblox.com/2014/07/roblox-arrives-on-android/|website=http://blog.roblox.com/|publisher=ROBLOX Corporation|accessdate=6 March 2015}}</ref><ref>{{cite web|last1=Hendrik|first1=Jack|title=ROBLOX Arrives in the Amazon App Store|url=http://blog.roblox.com/2014/10/roblox-arrives-in-the-amazon-app-store/|website=http://blog.roblox.com/|publisher=ROBLOX Corporation|accessdate=6 March 2015}}</ref> 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]].
During the alpha period, only selected places such as Crossroads, Paintball!, ROBLOX Snowmobiling, Dodgeball!, etc. could be played from the application.<ref name="ROBLOX Corporation"/> 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.
=== Holiday traditions ===
During holidays like [[Easter]], [[Halloween]], or [[Christmas]], Roblox will adapt the website to resemble the season. For example, during Halloween, the website theme will be black, orange, and purple, with a [[pumpkin]] representing the "o" in ''Roblox''. During Easter, Roblox sets up a level where players can search the world for "eggs" to collect and earn as hats for their character. On Halloween and Christmas, Roblox creates "gifts" that the players can earn or buy. After the gifts are no longer obtainable, they will open after a set period and give players a specific unique item. Unlike other holiday traditions, the 2015 egg hunt had featured games made by developers, other then a Roblox map done the years before. Many of the recent traditions have been sponsored by movies and TV shows, which has been subject to severe criticism from the game's community.
