Regular stage

Due to the vast number of matches and players involved, it's not possible to display the match results of the Regular stage in full here on the wiki. Instead, detailed information on these matches can be found in the information spreadsheet.

Ruleset

General

1. The GB Cup 2025 Spring is a point-based weekly group tournament, played on the osu!mania game mode.

   • Points earned by players in weekly matches are converted based on the total ranking of the mappool.
   • The total ranking of the mappool is based on the sum of the rankings of each player in each map.
2. Beatmap scoring is based on Score V2.
3. The GB Cup 2025 Spring consists of 4 groups (EX, S, A, and B), with only 2 groups playing each week.
4. The maps for each round will be announced by the mappool selectors on the official stream, on the Saturday before the actual matches take place.
5. Players will need to schedule their match time before the start of the match every week.

   • Players with special time requirements will need to contact the organiser in advance. The organiser does not guarantee that anyone's request will be met, and players will need to properly communicate with the referees.
6. Prior to the scheduled time, a referee will create a room for the corresponding players to enter in advance.
7. There is no warm-up phase for the match.
8. Use of the Visual Settings to alter background dim or disable beatmap elements like storyboards and skins is allowed.

   • Custom skin elements must not be used to alter core gameplay mechanics.

Registration

1. Players must fill in this form to register.

   • Player must join this QQ group or this Discord server after registration.
   • For players who cannot use QQ, please use osu! or Discord to contact the tournament management and Discord to communicate.
2. To ensure valid and serious registrations, every registered user will be manually checked by the host.

   • There are no rank limitations for this tournament.
   • To be successfully registered, a player must not have violated any osu! community rules within the last 12 months.
   • Upon registration, the tournament management may refer to the player's play counts to determine their actual playing skill. Heavy derankers and smurfs may be forcibly moved into a higher group (see below table).
3. A list of all successfully registered players will be published after the registration phase.
4. All successfully registered players will be grouped as follows:

5. If the 4K pp of a player is much higher than the upper limit of their group, they will be forcibly moved into a higher group. The buffer limit for each group is 100 pp.
6. Tournament staff members may not participate as players in the tournament.
7. The tournament management reserves the right to promote players that are considered to be too strong in their initial groups.
8. The tournament management reserves the right to decline restricted players from participating in the tournament.
9. Players are allowed to request for their group to be revised. In order to do so, such requests will need to be accompanied with screenshots of adequate scores from higher-level mappools to the tournament management.

Win conditions

1. In the Regular stage, players need to get high placements in higher groups in order to get more points. The points that can be earned are determined by the placement in every round, which is determined according to the average rank for all individual beatmaps in a round.
2. A base amount of points depends on the placement per round, and it is increased by a multiplier that depends on the group of players. The calculation method is as follows:

3. The final Regular stage ranking depends on the total amount of points from all 4 rounds. The top 24 players will advance to the playoff stage.
4. The top 8 will play in the winners' bracket, while the top 9–24 will play in the losers' bracket.
5. In case of a tie in the rankings, the player with a lower sum of ranks after every round will take the higher rank.
6. In the playoff stage, players need to win 6 beatmaps in order to win a match during Quarterfinals and Semifinals, and 7 beatmaps in the Finals and Grand Finals.

Match procedures

1. A referee will create a multiplayer room 5 minutes before the scheduled match time. Players must join the lobby in that period.

   • The room settings are as follows: Game mode: osu!mania, Team mode: Head-to-Head, and Score mode: ScoreV2. The room name must follow the pattern of the following example: GBC 2025 Spring: Lv.EX R1 | Sun 22.
2. Possible mod choices for the Free Mod bracket are No Fail, Hidden, Fade In, Flashlight, and Mirror.
3. The referees will select the beatmaps in order to play the match. If a player encounters a technical problem during a match, players may request a rematch from the referee after all the beatmaps have been played.

   • "Lag spikes" will not be considered as a valid reason to rematch a beatmap.
   • The rematch should happen after completing scores for the other beatmaps in the mappool.
   • Quitting the room and requesting a rematch after the map starts will only be allowed once in a match, and may also be vetoed by a referee.
   • This rule is not to be abused. Referees may veto a rematch request if they find that this is the case.
4. Unless there are special reasons, the organiser will only record each player's first score of the beatmap in the match room.
5. The default rest time is 120 seconds. If all players in the room agree to start early and get ready, the referee may start the match early.
6. Players are expected to keep the match running fluently and without delays. Excessive delays from the players' side may result in penalties being applied at the referee's discretion. Disrupting the match by foul play, insulting or provoking other players or staff, delaying the match, or other deliberate inappropriate misbehaviour are strictly prohibited, and will be punished accordingly.
7. All players and staff must be treated with respect. Instructions from referees and the host are to be followed. Decisions labelled as final are not to be objected.
8. The multiplayer chat rooms underlie the osu! community rules.
9. Disrupting the match by foul play or seed manipulation will result in disqualification, and any such players will be announced.
10. Unexpected incidents will be handled by the host. Referees may allow higher tolerance depending on the given circumstances. This is up to their discretion.
11. The host may request liveplays or recordings of individual players at any point.
12. The host reserves the right to modify these rules at any moment. Any such changes will be announced in advance.

Mappool information

1. Each group has four mappools, with one mappool to be played in every week.
2. Each mappool consists of 7 beatmaps that will all be played under Free Mod conditions. This means that there is a unique Free Mod bracket.
3. The composition of the beatmap slots in the mappool may vary from round to round.

Scheduling information

1. Each stage of the tournament is played in the duration of 2 weeks.

   • Group EX will play in the same week as Group B, and Group S in the same week as Group A.
2. All matches will be held between Saturday 09:00 and Sunday 23:00 (UTC+8) save for exceptional circumstances.
3. The tournament management will provide a list of possible match times before the start of matches each week, allowing for a schedule that is satisfactory to all players.

   • In case a special match time is required, please inform the tournament management in advance. The tournament management will try to comply to the request to the best of their abilities, but cannot make any guarantees.
4. Matches may not be scheduled to any time beyond Sunday, 23:59 (UTC+08) of the week they are to be played at.

   • Even if a delay is absolutely necessary, the match must be completed by the next Wednesday; later reschedule requests will be rejected.
   • Do not ask for a reschedule unless it is absolutely needed. The host reserves the right to deny any reschedule requests.

Playoff stage

The rules are largely the same as in the regular stage.

1. The organiser will invite the highest ranking players from the regular stage to participate in the playoffs.

   • If invited players decline for any reason, their slots will be passed on to the highest-ranked players who didn't qualify from the Regular stage.
2. There will be four separate mappools for each playoff round, with a varying number of beatmaps of different types:

3. Players will have 2 minutes to protect, pick and ban a beatmap, and 2 minutes to get ready. If a player takes more time than allowed, the procedures adopted will be as follows:

   • For map bans or protects, the player forfeits the ban or protect.
   • For map picks, a random map will be chosen from the mappool using !roll X, where X is the number of maps that were neither picked nor banned, excluding the tiebreaker.
   • For a ready timer, the referee will use the !mp start 10 command.
4. Each player will receive one tactical timeout of 2 minutes, to be used as extra time to pick or ban a beatmap. The tactical timeout is optional.

   • The tactical timeout may be called on a tiebreaker, provided that all players agree to it.
5. A referee will create a multiplayer room 10 minutes before the scheduled match time. Players must join the lobby in that period.

   • The room settings are as follows: Game mode: osu!mania, Team mode: Team Vs and Score mode: ScoreV2. The room name must follow the pattern of GBC 2025 Spr: ({Player A}) vs ({Player B}).
6. Each player must use !roll once in #multiplayer.

   • The winner of the !roll chooses whether to protect first or ban first. The player who protects first will also pick first.
   • Each player may protect one beatmap from the mappool. These beatmaps cannot be banned by any player in the next phase.
   • Each player may ban one beatmap from the mappool. These beatmaps cannot be picked by any player for the entire duration of the match.
   • Both players will alternate picking a beatmap from the mappool.
7. In the case of a tie, the beatmap will be rematched, but not more than twice.
8. Players are allowed to ask for a rematch if any player disconnects early on during a beatmap. Affected players are advised to send a message as soon as possible in the chat to notify the referee to restart the match.

   • The match may only be aborted before 30 seconds or 1/4 of the beatmap has elapsed, whichever comes first.
   • The same mods and beatmap must be used when the match restarts.
   • Please make sure to resolve any technical issues before restarting the match.
9. For matches in same quarters of a bracket, if there are 2 adjacent matches that are going to be played at the same time, the players may confer and request for the matches to combined into a 1v1v1v1 brawl match. If agreed upon, the process of match will be adjusted as follows:

   • All the 4 players start the roll, according to the order of roll, each one protect 1 map by descending order, then ban 1 map by ascending order, then pick 1 map by descending order, then pick 1 map by ascending order. Totally ban 4 maps and pick 8 maps.
   • According to the ranking of single maps in room, the highest score get 4 points, then 3 points, 2 points and 1 point.
   • If the remaining maps is not sufficient to change the current ranking in room, the match will be ended in advance. If there is still a tie after all the maps, then the Tiebreaker map will be picked. The result of the Tiebreaker map will only influence the outcome of players whose score are tied, with other players unaffected.
   • If the combined matches are from loser bracket double match, then only 1 of 4 players will get approved, no need to play the second round match of loser bracket; if they are from winner bracket, then 2 of 4 players will get approved, even though they are origin opponents.
   • If there is necessary reschedule, the combined matches could be split again.
10. Unexpected incidents will be handled by the host. Referees may allow higher tolerance depending on the given circumstances. This is up to their discretion.
11. The host may request liveplays or recordings of individual players or teams at any point.
12. The host reserves the right to modify these rules at any moment. Any such changes will be announced in advance.
