ROtris is a GUI-based game by Stravant (previously xLEGOx). It is a Roblox version of Tetris. An exact copy was created by Roblox for an event with the same name as the game, with prizes called "Tetraminoes", which are now no longer obtainable. The official game is now broken and closed to visitors, but many people have made "fixed" versions. From September 2012, it became uncopylocked, but later became copy locked and closed permanently.
ROtris was created on November 26, 2008. During the next following weeks, it has quickly gained 144K+ player visits and 6,646 favorites before closing down. It was last updated the following month on December 16, 2008.
