Studs

Studs is a square shaped with a 'R' sign on it representing ROBLOX. It first started with a circle shape with the 'R' letter on it, but then it was changed to square studs due to a copyright from the LEGO company. This caused ROBLOX to change the whole thing to square shaped studs instead. They are also a simulation to the LEGO and Blockland's studs. However, Blockland was created after ROBLOX but their stud shape was created before them.

Trivia

 * The ROBLOX studs look like the LEGO studs.
 * The ROBLOX studs also look like the Blockland studs, except that Blockland made their square shaped studs before ROBLOX did.
 * Studs are also used in ROBLOX measuring.
