Overview

The format of the tournament is largely taken from The Big Deal: 3D in the Dallas, TX area. The “Pocket Pick” mechanic was taken from Mistake on the Lake 2 in the Cleveland, OH area. Thanks to EvilDave and ranatalus for their hard work creating great tournament rule sets.

Machine Usage

Round1 San Jose will have four DanceDanceRevolution machines:

  • DanceDanceRevolution A20 (20th Anniversary “Gold cab”)
  • DanceDanceRevolution A (UNIANA White “K-cab”) [Primary]
  • DanceDanceRevolution A (Original White “J-cab”) [Secondary]
  • DDR SuperNOVA 2

As of 5/19, the Upper Division tournament will be held on the two “white cabs” only, with the DDR A20 and SuperNOVA2 machines usable for warmup. The tournament Twitch stream and Top 16 bracket will be run from the primary “white cab”. We may consider the use of the “Gold Cab” as the primary machine based on hardware performance and player feedback.

Qualifier

The qualifying round will be held remotely. All players must have paid for the event and tournament registration through the Infinity Stage smash.gg page. Scores from unregistered players will be rejected.

Please submit your qualifier information here: DDR Qualifier Submission Form

Songs:

  • High School Love (Expert 13)
  • Pierce the Sky (Expert 14)
  • Horatio (Expert 15 — NOT Challenge)

Qualifiers must be finalized by 3AM Pacific Time / 6AM Eastern Time on Friday August 9. Pools will be announced later that day and will be locked upon announcement.

Qualifier scores will be automatically retrieved from the e-Amusement system every 24 hours. The player’s best “machine score” or “money score” (NOT “EX score”) for each song will be added together to yield a total qualifying result. There are no restrictions on the number of times the songs may be played. The final score update will occur on the morning of August 9. During the retrieval process, if a song has not been played, a zero score for that song will be used. The automatic qualifier rankings will not be visible to participants or the public.

The player’s e-Amusement play data must be set as public in order for the qualifier retrieval system to work. This is the default setting. If you do not wish to change your score visibility settings, email photos of your qualifier scores to rogerclark@gmail.com with the subject “Infinity Stage”. We will attempt to contact any players whose visibility settings have been set as private.

Card Draw

Upper Division

Pools

The initial stage of the tournament will consist of “pools”: small sub-tournaments to organize play times and expedite progress toward Top 16.

The first two rounds of each pool will be single elimination, where the winner of each match is decided by the highest combined EX Score over the two songs played. In the event of a tie, songs will be drawn until one player wins.

Top 4 and onward for each pool will be double elimination, where the winner of each match is decided “best 2 of 3” (“first to 2”), and the winner of each song is decided by the highest EX Score on the song. In the event of a tie, neither player is awarded a point, and songs will be drawn until one player wins at least 2 songs.

1st place from each pool will advance to the Top 16 Winners Bracket. 2nd place from each pool will advance to the Top 16 Losers Bracket.

Top 16

At the beginning of Top 16, players will choose a “Pocket Pick” song from Levels 15-19. This song can be used once in the following manner: during a match card draw, after songs are drawn but before songs have been eliminated, a player may opt to replace one of the drawn songs with the “Pocket Pick”. The player using the “Pocket Pick” automatically uses their “Protect” for the round on this song. The “Pocket Pick” can be used if the song is already in the draw (to prevent it from being removed by the other player’s Pocket Pick). The lower seed must declare their intention to use their Pocket Pick after seeing the draw, but before the higher seed declares their intention to use their Pocket Pick. If both players use their Pocket Pick, the higher seed cannot remove the lower seed’s Pocket Pick.

At the start of each match, players will decide on the following:

  • Choice of 1P or 2P side
  • Choice of first veto or second veto during song draw.
  • Choice of first protect or second protect during song draw.

The higher seed will have first selection of these options. The lower seed will get their choice of remaining options, and the higher seed will have the remaining third option (if necessary).

Round Match Format # of Songs Drawn
Initial Pool Play Total EX (2 songs) 4 songs
Pool Play Top 4 Best 2 of 3 (First to 2) 5 songs
Top 16 Best 2 of 3 (First to 2) 5 songs
Winners/Losers/Final Best 3 of 5 (First to 3) 7 Songs
