  1. There will be qualifier lobbies open throughout the qualification weekend; players can sign up for whichever lobby fits their schedule.
  2. Each lobby can hold up to 15 players.
  3. Each lobby will have 1 assigned referee.
  4. The lobby will play through the entire map pool once, and your score after every map will be recorded.
  5. Failed scores will count as zero points; if a player revives before the end of the map, their score will count as normal.
  6. Players are not directly competing with the other players in their lobby.
  7. Players will be given points based on their performance on each qualifier map. The best score on a map earns a player 1 point, the second best 2 points, etc.
  8. Players' points on each map are added up to produce a total point score.
  9. The players with the lowest total point scores will advance to either Group Stage or RO64

  1. A referee will make the lobby 15 minutes before the match. Players must be online to receive their invites.
  2. If a player does not show up by 10 minutes after the scheduled match start time, they lose their ban(s).
  3. If a player does not show up by 15 minutes after the scheduled match start time, they forfeit the match and are blacklisted from the next iteration of Dio's Bizarre Tournaments.
  4. If a player gives prior notice that they cannot make their match, staff will attempt to reschedule the match with their opponent. However, there is no guarantee a reschedule will be successful. Additionally, staff will not blacklist the player from the next iteration of Dio's Bizarre Tournaments.
  5. Each player gets 1 ban from RO64 to RO16 and 2 bans from QF to GF. Banned maps are effectively removed from the mappool for that match.
  6. Both players can ban 2 maps of the same mod pool. However, from QF to GF, a player may not use both their bans on the same mod pool unless they double-ban nomod.
  7. Each player has 120 seconds to pick/ban a map. After the choice has been made, players have 30 seconds to ready up for the map.
  8. Failed scores will count as zero.
  9. In the case of a genuine disconnection in the first 30 seconds of the map, the map may be replayed. This can only be used once in a match per player. If a player disconnects on the same map twice in a row or on two different maps, they must deal with the consequences of their disconnect. This rule is to prevent abuse through manually leaving the game after missing on a map.
  10. On FM, both players must use Hidden, Hard Rock, Easy, and/or Flashlight.
  11. Scores with the Easy modification will be multiplied by 1.75.
  12. You are allowed to use, but not required, to use any of the above mods on the tiebreaker.

  1. In the event of a group stage, there will be 16 groups of 5 players, with the top 2 players from each group advancing to the subsequent RO32.
  2. A referee will make the lobby 15 minutes before the match. Players must be online to receive their invites.
  3. If a player does not show up by 10 minutes after the scheduled match start time, they lose the match.
  4. Each player gets 1 ban. Banned maps are effectively removed from the mappool for that match.
  5. Both Players can ban 2 maps of the same mod pool.
  6. Each player has 120 seconds to pick/ban a map. After the choice has been made, players have 30 seconds to ready up for the map.
  7. Failed scores will count as zero.
  8. In the case of a genuine disconnection in the first 30 seconds of the map, the map may be replayed. This can only be used once in a match per player.

This rule is to prevent abuse through manually leaving the game after missing on a map.
  9. On FM, both players must use Hidden, Hard Rock, Easy, and/or Flashlight.
  10. Scores with the Easy modification will be multiplied by 1.75.
  11. You are allowed to use, but not required, to use any of the above mods on the tiebreaker.

  1. BWS, or Badge Weighting Seeding, is a method that seeds players more accurately based on the number of badges they have, and enforces rank restrictions based on the player's number of badges.
  2. In other words, BWS "ranks up" players based on the number of badges they have.
  3. In terms of how much a player ranks up per badge, each badge is worth more than the one before it.
  4. The formula (originally by steve_04, but modified to be more aggressive) is as follows:
    BWS rank = rank^(0.99^(badges*(badges+2)/2))

  5. The rank cap is 1.00 BWS. You cannot go further than this.
  6. This is not a measure of skill. Read the first bullet point again.
  7. Sample values of the BWS formula can be found here.
