Glitch is a tournament series hosted by Tantalus and Xanadu Games in Laurel, Maryland. The series has hosted Super Smash Bros. for Wii U tournaments the most, although they have recently made the transition to Super Smash Bros. Ultimate. The series holds unconventional side events at every tournament, much like how glitches are unconventional. Some of the events included are low tier singles, mid tier singles, custom singles, triples, Super Smash Bros. Brawl singles, ARMS singles, amiibo singles, speedrun brackets, Squad Strike, and Morph-Meter.
2016-18: Super Smash Bros. 4
The first Glitch tournament will happen on March 12th, 2016, and will be hosted by Tantalus and VGBootCamp. It will solely focus on Super Smash Bros. for Wii U singles and doubles, but it will also start the trend of Glitch tournaments having unique side events, in the case being low tier singles (which followed the first Smash 4 tier list shown by VoiD and Snow using Mewtwo and Lucina, both of which being ranked much higher in later iterations) and custom singles. Glitch will also be the largest Glitch Smash 4 tournament, being the only one to have over 200 attendees.
Glitch 2 will start a side event for Super Smash Bros. Brawl singles, start hosting triples as a side event, and continued to host custom and low tier singles (this time following the second iteration of Smash 4's tier list).
Glitch 3 will keep Brawl singles, but many of the other side events were overhauled: keeping triples, removing custom singles, changing low tier singles to mid tier singles, and added amiibo singles, the former in which is currently the final time this event was hosted at a Glitch tournament. This will be the last Glitch tournament hosted by VGBootCamp until Glitch 7. The next three Glitch tournaments will be directed by Xanadu Games, which was also the venue every Glitch tournament takes place in.
Glitch 4 will drop Brawl singles, but bought back custom singles and keep amiibo singles as side events.
Glitch 5 currently has the lowest amount of attendees of all entries, with only 122, and the only Glitch entry to have no additional Smash 4 side events, instead being replaced with speedrun brackets and ARMS singles. This is so far the last Glitch tournament to primarily focus on Smash 4 as Super Smash Bros. Ultimate will later be released nearly three months later, and all future entries in Glitch will use that installment.
2019-present: Beginning of Super Smash Bros. Ultimate at Glitch
With the release of Ultimate, the Glitch series switched its focus to that game, completely abandoning Smash 4. The attendance for Glitch 6 singles was noticeably larger compared to the previous five, with a staggering 551 attendees (a 429 increase from Glitch 5). There were two side events, both being completely unique to Ultimate: Squad Strike and Morph-Meter.
Glitch 7 - Minus World had a slight increase in attendees and is now the largest Glitch tournament to date. Squad Strike remained one of the two side events of the tournament and Morph-Meter was replaced with amiibo singles. This tournament was mainly themed around the Super Mario franchise: the "Minus World" part of its name was a reference to "World -1", a infamous glitch that appeared in Super Mario Bros. and its banner was themed after Super Mario World. However, some controversy will happen involving its demotion from a S-Tier to A-Tier. This event, commonly dubbed as "GlitchGate", was the result of Stroder's disqualification from the tournament, causing Glitch 7 to go below the typical 2,400 point threshold of an S-Tier. Many people didn't understand the decision, as MomoCon 2019 remained an S-Tier despite having over 50 smashers dropping out of the tournament.
