- This is an international osu! standard team tournament for the 250k-100k rank range with a little bit of a twist to it: there will be no official "matches".
- Instead of a standard double-elimination tournament format, teams will play 7 weeks of qualifiers with different mappools following difficulty progression of a standard tournament.
- At the end of each round, team scores will be sorted, and points will be given as per usual qualifiers procedures (see rules). The number of teams advancing on to the next round each week will be determined once there is confirmation on the number of teams participating in this tournament. This will be done so that about 4 teams will participate in the final round.
- Each team will have a minimum number of 2 players and can have up to 3 players.
- Any player whose rank is not in the rank range when registrations end will be subsequently removed from the tournament, no exceptions. If this results in a team not having enough members, then the team will be removed from participation in the tournament.
- If you fall in one of these categories, then you are not eligible to participate in NPC4: if you were restricted within the past 12 months, and/or if you have earned a profile badge.
- All players must join the Discord server by the end of player registrations; otherwise, your registration is void.
- All players will undergo a manual screening by admins after registrations end. Any players who have been screened out or found to have suspicious behaviors will be disqualified, and teams whose member counts drop below 2 will become free agents.
- Any remaining free agents after registrations end will be grouped by the admins into free agent teams.
- ScoreV2 and NoFail will be enabled in all lobbies.
- All times and dates will be in UTC (Coordinated Universal Time). The main sheet will have the current time in UTC for your convenience. Alternatively, you can Google to find your time in UTC.
- Each round, schedules and mappools will be released by Tuesday 0 UTC, and lobbies will be played in the weekend.
- Admins, Spreadsheeters, Mappoolers, Playtesters/Replayers, and Referees are NOT allowed to play in this tournament.
- Host/admins reserve the right to report any and all suspicious player activity to osu! staff for further instructions on possible disqualification of said players during the course of the tournament. Should this result in disqualification, the players’ team(s) will be disqualified from further participation in this tournament.
- Hosts/admins reserve the right to ban any players whose conduct is bannable on Discord and Twitch from participation in the tournament.
- Hostile behavior against any member of the staff or any participant in this tournament is not allowed at any time, and upon further examination, may or may not result in the team’s disqualification from the tournament.
Mappool Format
Because of this format, the mappool format has been slightly adjusted to replace FM with EZ and remove TB from all pools.
- Round 1: 5 NM, 3 HD, 3 HR, 3 DT, 2 EZ
- Round 2: 6 NM, 3 HD, 3 HR, 3 DT, 2 EZ
- Round 3: 6 NM, 3 HD, 3 HR, 3 DT, 2 EZ
- Round 4: 6 NM, 3 HD, 3 HR, 4 DT, 2 EZ

- Final Round: 8 NM, 4 HD, 4 HR, 5 DT, 3 EZ
- Players will be notified through the Discord server to sign up for various lobbies that will be scheduled each round.
- For each day lobbies are scheduled for, 2 additional extra lobbies will be available for teams to request specific times for. Any additional requests for extra lobbies are not likely to be accepted except in extreme cases under the discretion of the hosts/admins.
- At least 10 minutes before the lobby, the assigned referee will make the lobby and ping the players in the Discord server. Captains should be online in-game to receive their invites. The captain is then responsible for inviting the rest of their team. If the captain of a team is not online, the referee will invite any other player from that team, and that player will be responsible for inviting their team.
- Teams have up to 10 minutes after the scheduled lobby time to have at least 2 members present in the lobby. If a team fails to have at least 2 members present in the lobby after the 10 minutes pass, the team must forfeit their participation in the particular lobby and sign up for another one.
- No warmup will be played.
- The mappool will be played through ONCE in order.
- If a team is seen playing the round mappool more than once in a round without valid reasoning, they will be immediately disqualified from the tournament.
- Round results and MP links will not be released until all lobbies have finished.
- Round results will be ordered from highest to lowest relative score sum. The relative score sum for each team is the sum of all relative scores (team score / max score) across all maps in the round for that particular team.
