Jstris is a guidline tetris website established by jezevec10 (u/jez) in 2014. Players don't have to register to play singleplayer, 1v1, or multiplayer tetris, and they can change keys, controls (like DAS and ARR) and block skins to their liking. There is also a public Jstris Discord, where people can seek help in playing and gain new friends with a common interest.
Jstris is better than tetr.io

J stands for John Nash. Stris is urban terminology for “stress”. They call it jstris cus whenever Nash was stressed, he used to call up his buddies and kick their ass in Tetris (earlier they didn’t have computers ... so they used to handcraft blocks from wood and throw them down from a large height, and then run down and chop off rows as they were completed.
