The Classic Tetris World Championship (CTWC) is a video game competition series, hosted by the Socal Gaming Expo. The competition launched in 2010, during the filming of , to determine the world's greatest Tetris player.[1] In its first two years, the competition was held in Los Angeles, California,[2] but was moved to Portland, Oregon, in 2012, and was held there annually through 2023 (with the exceptions of the 2020 and 2021 tournaments, held online due to the COVID-19 pandemic). The 2024 edition has been held in Pasadena, California.[3]
The contestants play the 1989 Nintendo version of Tetris on Nintendo Entertainment System consoles and cathode-ray tube (CRT) video displays. All of the tournaments are streamed online with live-edited screens and heads-up display to improve viewer experience. The tournament was initially dominated by Jonas Neubauer, who reached the finals in the first nine iterations of the tournament and won seven titles.
Following Neubauer's final win in 2017, before his sudden death four years later, the tournament came to be dominated by hypertapping, a style of playing in which the player rapidly taps the controller's D-pad to move pieces. This is in contrast to the delayed auto-shift (DAS) technique, in which the player simply holds down the D-pad to move the piece. Hypertapping was especially prevalent among a recent influx of younger players, a group largely inspired to pick up the game by Joseph "JdMfX_" Saelee, who won back-to-back titles while in high school, including a win against Neubauer in the 2018 final and one against Koji "Koryan" Nishio in the 2019 final. Thirteen-year-old Michael Artiaga dogplayingtetris won the 2020 edition of the tournament, beating his brother Andrew Artiaga "PixelAndy" in the final. Michael defended his title in 2021, defeating Jacob "Huffulufugus" Huff three games to one.
Although Huff fell short, he showed the effectiveness of a brand-new style of play, known as "rolling." Originally introduced by CTWC regular Chris "Cheez" Martinez, the playstyle involves partially depressing the controller's D-pad with one hand, while tapping the back of the controller with the fingers of the other, pushing the controller the rest of the way into the first hand and registering an input. The new strategy has brought in a wave of scoring records, with the world record more than quadrupling, and has seen former DAS players and hypertappers (including the Artiagas) adopt the playing style.[4]
The 2022 tournament, held in Portland for the first time in three years, was dominated by rollers. Eric "EricICX" Tolt defeated Justin Yu "Fractal161" to win the title three games to one. The third game saw both players exceed 2.1 million points, with Tolt winning the game and later the crown.
The 2023 event saw Yu win his first title, coming from 0–2 down to defeat Eve "Sidnev" Commandeur of the Netherlands 3–2 in the final. Commandeur also set the qualifying record with 16 max-outs,[5] which was tied by both Willis Gibson "Blue Scuti" and Noah Dengler in the 2024 event.[6]
In the 2024 tournament, held in Pasadena for the first time, Alex Thach claimed his first title, topping Michael Artiaga (dogplayingtetris) in a decider.
The competition takes place over two days, with the qualifying round on the first day and the main event on the second. Contestants are allowed to bring their own controller, but it must be either an original, unmodified NES Controller or an aftermarket unit that is deemed a faithful enough reproduction of one. The competition winner and second place runner-up are awarded with the Jonas Neubauer Memorial Trophy, a J tetromino shaped trophy named for the late 7-time champion Jonas Neubauer. Prior to Neubauer's death in 2021, the trophies awarded to competition winners were T tetromino shaped.[7]
Qualifying takes place on a fixed number of NES stations. Entrants play "Type A" Tetris, starting on level 9 or higher, and are seeded based on their final score. Once an entrant's game ends for any reason, their score must be recorded by a tournament scorekeeper in order to be valid. Entrants may make as many qualifying attempts as they wish, but must return to the back of the waiting line for each one. Entrants may also pay a fee to rent a station for one hour, which allows unlimited qualifying attempts. In 2022, the lines were discontinued and each player could register for a two-hour time slot in which to make as many qualifying attempts as desired.
The top 32 scorers are seeded into a tournament bracket for the main event. In 2018, 40 players were allowed to qualify, with a "Round Zero" play-off held among the bottom 16 seeds to reduce the field to 32.[8] Forty-eight players qualified in 2016; the top 16 seeds automatically advanced, while the remaining 32 competed in "Round Zero" to fill the other 16 slots. In the event of multiple players maxing out (scoring 999,999 or higher), their second highest score is recorded to determine their seeding. This was especially utilized in 2018, when seven players maxed out, four of whom (Koji "Koryan" Nishio, Tomohiro "Green Tea" Tatejima, Jonas Neubauer and Harry Hong) maxed out twice. Thus, the officials needed their third highest scores just to determine the 1st to 4th seeding.[9]
The Main Event is a single-elimination tournament consisting of five rounds of head-to-head matches, with seeds from opposite ends of the rankings pitted against each other in the first round (i.e. #1 vs. #32, #2 vs. #31, etc.). Originally, competition games were played on unmodified NES Tetris game cartridges. Beginning from the 2016 tournament, the game code was modified to be capable of displaying 7-figure score values (prior to this change, the score would 'max out' at 999,999). Beginning from the 2023 tournament, game code was further modified such that at level 39, the speed of the falling pieces is increased to 2 cells per frame, effectively inhibiting gameplay past level 39.
Both players in a match play "Type A" Tetris, beginning on Level 18, at the same time on separate systems. The player who reaches a higher score wins the round.[10] Matches between players are best-of-three or best-of-five rounds, depending on the event.
In a manner similar to the National Invitation Tournament, a silver tournament for the top 32 players who did not qualify for the Main Event was started in 2020 with its own championship and trophy (not to be confused with the silver trophy for the runner-up in the Main Event). Some news media have incorrectly called the winners of this bracket "world champions".[11]
The inaugural Classic Tetris World Championship was held on August 8, 2010 at the Downtown Independent theater in Los Angeles, California. Los Angeles was chosen because several high-ranking players lived there.[12] Modeled after the 1990 Nintendo World Championships, eight players completed three Tetris challenges to decide the two finalists. Five of the eight seats in the semifinal were reserved for specific distinguished Tetris players: Jonas Neubauer, Harry Hong, Ben Mullen, Jesse Kelkar and Thor Aackerlund.[13] Neubauer won $1,000 after defeating Hong in the final. The tournament was attended by Henk Rogers and a film crew[12] for the 2011 documentary .[13]
The second annual championship was held at the University of Southern California's Bovard Auditorium on October 16, 2011[2] [14] [15] with financial support from Electronic Arts.[16] The main tournament was now a single-elimination tournament, and all matches were best-of-three.[15] Neubauer successfully defended his title against Alex Kerr in the final.[17] In addition to classic Tetris, tournaments were also held for EA's Tetris for PlayStation 3 (including both a solo and 2 vs 2 team tournament, with best-of-seven matches)[2] [15] [18] and the tabletop game Tetris Link.[14]
The 2011 tournament was expensive and poorly attended, and it was unclear if a third event would be feasible. In what Chris Tang describes as the tournament being "saved by a miracle", the Portland Retro Gaming Expoheld at the Oregon Convention Centermade arrangements for it to be held there in 2012.[16] Neubauer continued his winning streak in the 2012 and 2013 finals[19] which were now held as best-of-five matches.[20] His streak was interrupted in 2014 when he was defeated by Hong,[21] but he regained the title with his fifth championship win in 2015.[19]
Neubauer's opponent in the 2016 final was Jeff Moore, a dark horse who was performing strongly. Moore's impressive play got the commentators "overly excited", and they enthusiastically yelled Boom! Tetris for Jeff every time he scored.[22] Although Moore was not able to defeat Neubauer, the match became popular on YouTube where it was parodized.[23] Writing for Engadget, James Trew credits the Neubauer - Moore match and Boom! Tetris for Jeff with "piqu[ing] the interest of younger eyes and kickstart[ing] a growing appetite for competitive classic Tetris videos."[22]
After watching the Neubauer - Moore match on YouTube, 15 year old Joseph Saelee became interested in Tetris. He prioritized learning a rare playstyle called hypertapping, which by 2017 had only been used competitively by two playersThor Aackerlund and Koji "Koryan" Nishio. When hypertapping, the buttons on the game controller are pressed extremely rapidly with muscle tremors (rather than pressing and holding buttons). Within one year, Saelee had set numerous world records with the technique.[23]
Saelee, now 16 years old, entered the 2018 tournament hoping "just to qualify", without serious expectations for his first competition.[24] He was much younger than most competitors, who were in their thirties or forties. After defeating both Hong and Koryan, he had reached the final where he would face Neubauer.[25] Saelee won the final 3 - 0, becoming the new world champion.[26] He initially exited the stage speechless; Neubauer took the microphone to praise Saelee's play.[25]
The YouTube video of the Neubauer - Saelee match, titled "16 y/o Underdog vs. 7-time Champ", became the most viewed competitive Tetris match[25] and is credited with popularizing hypertapping and attracting young players to Tetris.[27] The 2018 event was shown on commercial television, with a recap airing on ESPN2.[28] Future recaps would air as part of ESPN8: The Ocho special programming.[29]
Saelee won back-to-back titles, defeating Koji Nishio.
Due to the COVID-19 pandemic, the 2020 event was held online with a different set of rules from the in-person tournaments.[30] Michael Artiaga (dogplayingtetris) won the final. He became the youngest-ever champion at 13 years and 16 days of age, defeating his 15-year-old brother Andrew Artiaga (P1xelAndy). Michael Artiaga scored back-to-back CTWC victories by defeating Jacob Huff in the 2021 final.
The CTWC returned to the Portland Retro Gaming Expo as an In-Person tournament with a similar format to 2019.[31] bThe number of players for the main tournament draw was expanded from 40 to 48, with a "Round Zero" play-off for qualifiers ranked #17 to #48. The winner of each "Round Zero" match faced one of the top 16 seeds in the first round proper (winner of #17/#48 vs. #16, #18/#47 vs. #15, etc.)
Qualifying
Playoffs
Qualifying continued to utilize the two-hour window format, with the most max-outs and highest tiebreaker scores (kickers), determining seeding and the Top 48.
Playoffs were once again Best of Five matches with Level 18 opens, but also featured the so-called "Super Kill Screen." This activated at Level 39 to encourage competitors to be more aggressive at Level 29-38 speeds, as opposed to outlasting an opponent by avoiding a top out.[32] This was mainly due to a technique called "rolling", in which competitors tap their fingers on the back of the controller in a rolling sequence to move pieces farther, becoming the dominant playstyle, to the point where high-level online games stretched beyond Level 100.
Alex Thach (AlexT) won the 15th event against the 2-time champion Michael Artiaga (dogplayingtetris) in a decider.

During the expo there have been several tournaments on other systems over the years.
There is a once-a-month online tournament called Classic Tetris Monthly (CTM) that was previously hosted on the same Twitch channel as the CTWC, but it now is hosted on MonthlyTetris. Competitors routinely compete from around the world in CTM, which is streamed remotely and thus allows for great flexibility on the part of the competitors. CTM is overseen and commentated chiefly by Keith "vandweller" Didion, who took over for Jessica "fridaywitch" Starr, the tournament's founder, in the Summer of 2018. Starr premiered the tournament on December 3, 2017, on her personal Twitch channel, with 16 participants that had qualified in the few weeks leading up to the event. Harry Hong, the 2014 CTWC champion, was the tournament's first victor. Didion opened a Twitch account dedicated to CTM, called MonthlyTetris, shortly after he began hosting. Additionally, the CTM Discord server is in many ways the center of the Classic Tetris Community, serving as its primary online meeting space.
Since 2015, a Classic Tetris European Championship has been played annually in Copenhagen. The tournament follows a similar structure, but is played on the PAL version of NES Tetris rather than the NTSC version. Due to the difference in framerates, the two versions of the game (both of which are designed for the NES) are balanced differently; pieces do not fall at identical speeds on the same level between the two versions. In addition, Delay Auto Shift (DAS) is faster in PAL compared to NTSC. At higher level play, this leads to significant differences in strategy and outcome. In particular, players who employ DAS as their primary strategy are able to play at the highest level.
