osu!catch Convert Cup Open 2023

The osu!catch Convert Cup Open 2023 (o!cCO 2023) was a double-elimination 2v2 osu!catch tournament hosted by Urabe Mikoto in which all the beatmaps were converts from the osu! game mode. The tournament was open to teams of osu!catch players with at least one player from Asia or Oceania in their roster. Although it was the first event to be held under the Convert Cup Open branding, the tournament was considered an expansion of the previously held Indonesia Convert Cup series.

Qualifiers

Detailed information on the standings of the Qualifier stage can be found in the following spreadsheet.

Ruleset

General rules

1. Beatmap scoring is based on ScoreV2.
2. The mappools for each round will be announced by the tournament management in advance before the actual matches take place.
3. Match schedules will be predetermined by the tournament management. If there are any teams who are unable to attend the current schedule for any reason, all other affected teams may apply and settle for a reschedule at the #reschedule channel in the tournament's Discord server.
4. A referee will create a multiplayer room 10 minutes in advance and will start to send out invites.
5. If a team does not show up or is unable to field in a sizeable 2v2 roster within 10 minutes of the start time, their opponent wins by default.
6. If no staff or referee is available, the match will be postponed.
7. NoFail will be enforced in all beatmaps. This is to ensure that the points are to be awarded more fairly towards teams who perform better in general during the course of the beatmap regardless of their remaining health at the end.
8. If a player disconnects, it will be treated as if they had failed the beatmap.

   • A beatmap can be replayed for disconnects that occur within a few seconds after it has been started by the referee.
9. Lag is not a valid reason to nullify a beatmap.
10. If any problems during the match occur, the tournament management will make a decision based on the referee's report.
11. It is expected that all players be polite and respectful to each other. Penalties will be given upon violation.

    • If a player is found to be engaging in an act that is deemed to be distasteful or provocative, the corresponding player or their team may be disqualified right away from the tournament and/or blacklisted from future iterations of the tournament by the tournament management.
    • Usage of any tools or programs that are against the osu! community rules is strictly prohibited and will be straight up reported to the osu! team at will.

Tournament registration

1. In order to participate, players are required to form a team and register into the tournament as a team through the tournament's website.

   • Each team is required to have least one player from Asia or Oceania in their roster.
   • For the sake of simplification, regions of certain transcontinental countries such as Azerbaijan or Russia that extends to the Asian continent are considered as a part of Asia.
2. Each team has to submit a designated team captain and a team name to the tournament management before the end of the screening phase.

   • Team names may not violate the osu! community rules.
3. To ensure that all incoming registrations are serious and valid, every registered player will be checked in detail by the tournament management.
4. The list of players and teams who are deemed to be eligible to compete in the tournament will be published by the tournament management after the registration phase has ended.
5. Testplayers, referees, and mappool selectors may not participate as players in this tournament.

Round-specific rules

Qualifier rules

1. Each team will have to sign up to one of the Qualifier lobbies that have been scheduled and prepared by the tournament management in advance.
2. In the lobby, all teams will have to consecutively play all of the eight Qualifier beatmaps in the order of NM1 -> NM2 -> HD1 -> HD2 -> HR1 -> HR2 -> DT1 -> DT2.
3. Teams are not allowed to ban any beatmaps in the Qualifiers.
4. Teams are not allowed to join (or register for) more than one Qualifier lobby.
5. Based on their performance in the Qualifier, teams will be ranked based on their average rank combined from each individual Qualifier beatmaps.
6. 32 teams with the highest average rank according to the above criteria will advance to the knock-out stages.

   • If there are two (or more) teams that share the same average rank, the teams will be ordered based on their average score across all eight Qualifier beatmaps.
7. Failure to attend in any of the predetermined Qualifier lobbies will result in an instant elimination from the tournament.

Knock-out stage rules

1. The 32 teams who got through from the Qualifiers will be matched against each other based on their Qualifier seeding (e.g. Seed #1 vs. Seed #32, Seed #2 vs. Seed #31, and so on).
2. Teams will compete against each other using the double-elimination system.
3. The double-elimination system works as follows:

   • Teams who lose in the upper bracket can still play again in the lower bracket.
   • Teams who lose in the lower bracket will be eliminated from the tournament.
   • In the Grand Final, the winner of the the upper bracket will only need to win a single match in order to claim the championship title. The winner of the lower bracket, however, will need to win two matches and enforce a bracket reset in order to clinch the championship title.
4. Teams who can compete in the next round are determined by:

   • In the Round of 32 and the Round of 16, each team needs to win 5 points in order to win a match. (Best of 9)
   • In the Quarterfinals and the Semifinals, each team needs to win 6 points in order to win a match. (Best of 11)
   • In both of the Finals weeks, each team needs to win 7 points in order to win a match. (Best of 13)
   • Whether there are teams who are declared to win the match by default.
   • Whether there are teams who are disqualified from the tournament.

Match regulations

1. Prior to starting the match, representatives from each team must run the !roll command in order to determine the banning and picking order.

   • The winner of the !roll gets to determine who gets the first pick and the second ban.
   • The loser of the !roll gets the opposite by default.
   • This rule does not apply in the Qualifier lobbies.
2. Each team has to ban one beatmap from the corresponding mappool. These beatmaps will not be allowed to be picked by any team during the entire match.

   • Barring the tiebreaker, there are no restrictions as to which maps may and may not be banned in a match.
3. Each team will be given a chance to pick one warm-up beatmap to be played in the lobby.

   • Playing a warm-up beatmap is not mandatory, and teams may elect to skip their warm-up pick should they wish to.
4. Excluding the Qualifiers, each stage of the tournament will feature a MixedMod pool that goes as follows:

   • The MixedMod pool will be played with FreeMod activated.
   • During a MixedMod pick, one player from each team will have to play the map with the Hidden mod activated, while the other player will have to play with either HardRock or Hidden+HardRock under their belt.
5. When playing a map from the HardRock or DoubleTime pool, the Hidden modification may be optionally used by any player.
6. In the case of a tiebreaker, the tiebreaker map will be played with the FreeMod option enabled. Players are free to play the tiebreaker map with Hidden, HardRock, or Hidden+HardRock should they wish to.

   • Playing the tiebreaker map with a mod is not mandatory.
7. The results of each match and any other relevant information regarding the match will be noted by the referee after the match has been concluded.
