DAILY AUTOMATED TOURNAMENTS

Guild Participation

  • For a team to be eligible, at least four (4) of the eight (8) members of a guild's team in a daily GvG automated tournament must have been a member of that guild for fourteen (14) days prior to the start of the tournament. The other four (4) players on the team can be guild members, guests, Heroes, or henchmen.
     
  • Teams may have different guild members or players compete in subsequent rounds but the same rule listed above applies. Only the eight (8) guild members who competed in the first round will collect any earned Tournament Reward Points.
     
  • A guild must have at least four (4) human players available to play during a match (in which case they may also use four (4) computer-controlled henchmen or Heroes). If a guild is unable to field at least four (4) human players, then that guild forfeits the battle.
     
  • Any guild officer can register a guild for an automated tournament using the Guild Battle button and selecting the Register for Tournament option from the list of possible guild battle types. Five (5) tournament tokens will be deducted from the inventory of the officer who is registering for the tournament.
     
  • Each tournament token costs 1,000 Balthazar faction points. You may purchase these tournament tokens from the Tournament NPC who appears in every guild hall as well as in the Great Temple of Balthazar and the Hero Battles arena.
     
  • GvG games will be played on the following maps in this order: Frozen Isle, Isle of Solitude, Isle of Meditation, Druid’s Isle, Isle of Wurms, and Nomad's Isle. If a tournament has more than six (6) rounds, the list will repeat.
     

1v1 Participation

  • Individuals interested in participating in a daily 1v1 automated tournament must have registered their accounts with a Tournament NPC (found in guild halls, the Hero Battles arena, and the Great Temple of Balthazar).
     
  • To register your account, simply select one of your character names. This name identifies your account in the ladder and in tournaments. You may change this name once every 30 days.
     
  • To register for an automated tournament, use the Hero Battle button (only available in the Hero Battles arena) and select the Register for Tournament option from the list of possible Hero Battle types. One (1) tournament token will be deducted from your inventory.
     
  • Each tournament token costs 1,000 Balthazar faction points. You may purchase these tournament tokens from the Tournament NPC who appears in every guild hall as well as in the Great Temple of Balthazar and the Hero Battles arena.
     
  • 1v1 Tournament A will be played randomly on one of the following maps: the Beachhead, Desert Sands, the Crossing, and Bombardment. Tournaments B and C will be played on the following maps in this order: Desert Sands, the Beachhead, Bombardment, and the Crossing. If more than four (4) rounds are played in any tournament, the same map order will be repeated.
     

MONTHLY AUTOMATED TOURNAMENTS

Guild Participation

  • At least six (6) of the eight (8) members of a guild's team in a monthly GvG automated tournament must have been a member of that guild for at least fourteen (14) full days prior to the announced start time of that tournament in order for the guild to compete. The other two (2) members of the team must be members of that guild but do not have to meet the fourteen (14) day requirement.
     
  • Guilds may have different players compete in subsequent rounds but the same rule listed above applies. Only the eight (8) guild members who competed in the first round will collect any earned Tournament Reward Points.
     
  • A guild must have at least six (6) human players available to play during a match (in which case the guild may also use two (2) computer-controlled henchmen or Heroes). If a guild is unable to field at least six (6) human players, then that guild forfeits the battle.
     
  • Any guild officer can register a guild for an automated tournament using the Guild Battle button and selecting the Register for Tournament option from the list of possible guild battle types. Five (5) tournament tokens will be deducted from the inventory of the officer who is registering the guild in the tournament.
     
  • Each tournament token costs 1,000 Balthazar faction points. You may purchase these tournament tokens from the Tournament NPC who appears in every guild hall as well as in the Great Temple of Balthazar and the Hero Battles arena.
     
  • For the November season the following maps will be used in this order: Frozen Isle, Imperial Isle, Nomad’s Isle, Isle of Wurms, Isle of Weeping Stone, and Druid’s Isle. If the monthly tournament runs more than six (6) rounds, the same map order will repeat.
  • For the December season the following maps will be used in this order: Frozen Isle, Isle of Solitude, Isle of Meditation, Druid’s Isle, Isle of Wurms, and Nomad's Isle. If the monthly tournament runs more than six (6) rounds, the same map order repeat.

1v1 Participation

  • The same rules and restrictions apply as in the daily 1v1 Tournaments.
     
  • The following maps will be used in this order: Desert Sands, the Beachhead, Bombardment, and the Crossing. If more than four (4) rounds are played in this tournament the same map order will be repeated.
     

Season Structure

  • Each month of the $100,000 Tournament Series is a "season." The seasons consist of a number of daily Swiss competition-based tournaments in which guilds (for GvG) or individuals (for 1v1) can participate. The number of registered participants determines the number of rounds for each tournament.
     
  • The K rating for Daily Automated Tournaments is 25. See Appendix B — Elo Ratings.
     
  • Automated GvG tournaments have a maximum of 32 participating guilds per event, with a maximum of five (5) rounds of Swiss competition.
     
  • Automated 1v1 tournaments have a maximum of 128 participants per event, with a maximum of seven (7) rounds of Swiss competition.
     
  • When more than 32 guilds or 128 individuals register for a specific automated tournament, additional copies of that tournament are created. Each copy has a minimum number of participants: eight (8) for 1v1 and five (5) for GvG. The copies have no more than the previously stated maximums. Thus it is possible, with a large number of participants, for several copies of a tournament to run simultaneously.
     
  • Each tournament and its copies offer the same prize opportunities.
     
  • The rounds of Swiss competition for each tournament take place consecutively one after another until a tournament ends. A list showing the tournament standings and the pairings for the upcoming round is available in-game for participants and fans to see.
     
  • All rounds are single battle matches.
     
  • Each round ends with one participant as the winner. In the event that a GvG match lasts to the time limit without a clear winner, the team whose Guild Lord has the higher current Health will be declared the winner of the match.
     
  • For all automated tournaments (GvG and 1v1), all participants are randomly seeded for the first round.
     
  • Each subsequent Swiss round pairs participants randomly against opponents with matching win/loss records.
     
  • Participants who forfeit a match for any reason are dropped from the remainder of the automated tournament. They still collect all prizes or rewards they have already earned.
     
  • At the end of the rounds of Swiss competition for each tournament, all participants may earn Tournament Reward Points (TRPs) and/or qualifier points (QPs) based upon their final rank in the tournament. In the event of any ties, these tie-breakers are used in the following order to determine final standings: match points earned, opponent's match-win percentage, and tournament ladder rank (captured at the start of the tournament). See Appendix A — Match Scoring and Tie Breakers.
     
  • At the end of each season, all guilds and individuals who have earned sufficient QPs are invited to participate in the appropriate end-of-season championship.

Connectivity

  • Due to the nature of computers and the Internet, ArenaNet is not responsible for the results of any disconnection or network problems experienced by players.

Daily Tournament Prizes

  • Tournament Reward Points (see section below).
     
  • In addition to earning TRP, high finishing guilds and individuals earn qualifier points (QPs). The numbers of QPs awarded in these daily tournaments are as follows:
     
Daily Tournament Result QP Points Awarded
1st 8
2nd 7
3rd 6
4th 5
5th 4
6th 3
7th 2
8th 1
  • At the end of each qualifier season, guilds that have earned sufficient QPs earn an invitation to compete in the monthly playoffs for that month.
     
  • Earned QPs are shown on the GvG and 1v1 ladders.
     
  • QPs are reset to zero for the next season one (1) hour after the start of a monthly playoff.
     

Tournament Reward Points

Tournament Reward Points are awarded at the end of a tournament to the top 25 percent finishers. Only guilds or players who have played at least one game receive points.

Formula:

"Winners" are defined as the top 25 percent of finishers.

((Number of Winners – (rank of each winner-1)) * Tournament Reward Points) / Number of Winners;

Tournament Reward points differ for GvG and 1v1, and for daily and monthly. The first place finisher would receive:

GvG Monthly: 120
GvG Daily: 60
1v1 Monthly: 40
1v1 Daily: 20

Additionally, players receive points for each single victory in a tournament as follows:

GvG Monthly: 6
GvG Daily: 3
1v1 Monthly: 2
1v1 Daily: 1

For example, if 40 people played in a 1v1 daily tournament, the top 10 winners (25 percent of the finishers, 10 out of 40) would receive the following amount of points:

((10 – (1-1)) * 20) / 10 = 20
((10 – (2-1)) * 20) / 10 = 18
((10 – (3-1)) * 20) / 10 = 16
((10 – (4-1)) * 20) / 10 = 14
((10 – (5-1)) * 20) / 10 = 12
((10 – (6-1)) * 20) / 10 = 10
((10 – (7-1)) * 20) / 10 = 8
((10 – (8-1)) * 20) / 10 = 6
((10 – (9-1)) * 20) / 10 = 4
((10 – (10-1)) * 20) / 10 = 2

All players, no matter their rank, are then given 1 point for each win in the tournament.

APPENDIX A — Match Scoring and Tie-Breakers

Match points are used for pairing and tie-breakers. Each guild or 1v1 player (hereby know as competitor) earns 3 match points for every match won, 1 point for any draws, and 0 points for any matches lost. Each competitor is assigned an additional 0 to 0.999 match points based on that competitor’s opponent's Match-Win Percentage.

Each AT participant's match-win percentage is that competitor's accumulated match points divided by 3, times the number of rounds played, or 0.33, whichever is greater. (Establishing a minimum match-win percentage of 0.33 limits the effect low performances have when calculating and comparing Opponent's Match-Win Percentages.)

For example, a competitor's record is 2-1-1 (2 wins, 1 loss, and 1 draw) after 4 rounds of Swiss play. That competitor has earned 7 match points and has a Match-Win Percentage as follows: 7/(4*3) = .583

A competitor's Opponent's Match-Win Percentage is the average Match-Win Percentage of each opponent that competitor faced (ignoring any rounds for which the competitor received a bye or forfeit).

For example, using the above example, a competitor finished 2-1-1 and its opponents' match records were 2-2-0, 1-2-1, 3-1-0, and 0-4-0, so the competitor's Opponent's Match-Win Percentage is as follows:

(6/12 + 4/12 + 9/12 + 0/12)


4 opponents

Replacing the 0/12 with 0.33 (see above minimum) and translating to the decimal system we get:

(0.50 + 0.33 + 0.67 + 0.33)

This equation becomes 1.83

or 0.46.

This number, which ranges from 0.33 to 1.0 is then scaled to range from 0.0 to 0.999 (for readability) and then added to the competitor's score.

The scaled number is calculated as follows:

(Opponent Win Percentage-0.33) * (0.999/0.67)

In our example above, the competitor has 7.19 points. (7 from its 2 wins and 1 draw, and 0.19 based on an Opponent Win Percentage of 0.46.)

While this may seem a bit complicated, it basically comes down to using the strength of a competitor's schedule as the tie-breaker. The competitor who defeats opponents with better records ends up with a slightly higher score than those competitors who defeated weaker opponents.

Further, each competitor's ladder rank is captured at the start of a tournament. In the event that any ties remain after accounting for Match Points Earned, the ladder rank at the start of the tournament is used to break ties, with better-ranked participants beating worse-ranked guilds (example: a competitor ranked 5th on the ladder beats a competitor ranked 12th on the ladder).


APPENDIX B — Elo Rating System

The Guild Wars Tournament Ladders use the Elo ratings system.

This Elo rating system compares a guild or 1v1 player's (hereby know as competitor) match records against opponents' match records and determines the probability of that competitor winning the matchup. This probability factor determines how many points an Elo rating goes up or down based on the results of each match. When competitors defeat opponents with a higher rating, their Elo rating goes up more than when they defeat opponents with a lower rating (because competitors have a high probability of defeating those with lower ratings). All new competitors start out with a base rating of 1000. The Guild Wars tournament ladder uses the following equation to determine a competitor's win probability in each match:

Win Probability = 1

10^((Opposing Elo Rating–Your Elo Rating)/400) + 1

This probability is then used to recalculate each competitor's rating after the match. In the equation below, competitors receive 1 point if they win the match and 0 if they lose. The competitor's new ratings are determined as follows:

Competitor's New Rating = Competitor's Old Rating + (K-Value * (Scoring Points–Competitor's Win Probability))

All competitors are rated beginning with the first rated match in which they play. Further ratings are calculated chronologically from that first match.

The K-Value is the maximum number of points a competitor's rating may go up or down based on the results of a single match within an event that uses the Elo ratings system. The current K ratings ArenaNet uses are as follows:

  • The K rating for free play matches is 5.
  • The K rating for Daily Automated Tournaments is 25.
  • The K rating for Monthly Championships is 50.
