Rules

Director Co-Director	Tomawaky – Franck DEL RIO
Type of Tourney	The Goes On If Under 3 Loss : It is a Swiss random pairment, where players are dropped by the end, as soon as they loose their third match. The winner will be the last player with less than 3 loss. I want to thanks Neil Kazaross who has proposed this way to run the tourney. Cause it's not usual and all the players have found it interesting.
Eligibility	The tournament is open to Serious players only.
Subscription	Will be done from the subscription Page ;-). This page is mentioned in the appropriate forum.
Place	Fibs. While the directors cannot enforce this, it is strongly encouraged. Note that matches absolutely should not be played on servers that do not allow saving of matches in the event one player is booted. With the aggrement of both players, the match could be played anywhere else like TMG, GG, PartyGammon, PartoucheGammon, ...etc. Agreement between players is the best thing but it is needed to select one in case of no agreement.
Fees and Prizes	The tournament is free to enter and no prizes will be awarded.
Format	Matches are to be played using the Crawford rule, doubling cube and allowpip toggled on. Match's Lengths will be fixed to 15 Pts for the swiss part and increase in the Play-Off. It is mandatory that you save your matches. This may be helpful in case of a dispute and all matches would be available to other players for analysis.
Scheduling	At the beginning of a new round, the Director will send an email to all participants inviting them to contact their opponent as soon as possible to complete their match. Please do not wait long before the deadline to contact your opponent. The tournament is world wide and finding a mutual time to play may require more than a few days. Don't forget the place where the match would have to be played. You will be able to send an email to your opponent via the website, using hyperlink attached to the pseudo, in the players and matches pages.
Deadlines	You must make your best effort to complete your match or at least plan it in the first 2 weeks. Extension can be granted if you have difficulties to find a mutual agreement or if one player is in vacation. Remember that in a swiss mode, a new round can start only when all matches are completed. The Goal of this tourney is taking pleasure and to complete all of the match rather than put some deadlines and put some inflexible rules. So thanks to make your best effort to plan as soon as possible your match.
Forfeitures and No Results	If a player has made a legitimate effort to contact his or her opponent with no response, a forfeit may be requested on the due date. At least three email attempts have to be made before a forfeit will be granted. Please try to schedule your matches early to allow for unforeseen events. Also, please save all scheduling email until the tournament has ended. In the event neither player posts any results, the opponent of the next round will receive a bye.
Report	First, the post must be done by the player who has lost, giving the score and the length match. Then the winner would have to confirm and upload the match file. For each match to be played in our tournament, you must come here to report the results.
Drops and Disputes	If a player drops during the match, the opponent should wait at least 15 minutes for the player to return. If the player does not return, the match must be rescheduled BEFORE the deadline. If the match cannot be rescheduled before the deadline, the tournament directors MAY award a victory to the player ahead in the match or they MAY determine that No Results are the outcome. The decision of the tournament directors shall be final. Evidence such as email correspondence, dice logs, etc., should be retained until after the tournament.
Principles of a Swiss System tournament	The number of rounds to be played depend on the number of players. Two players may play each other only once. Players are paired with others of the same score, or nearest score. The final ranking order is determined by the aggregate of points won: 1 point for a win, 0.5 point for a draw and 0 point for a loss. A player whose opponent fails to appear for a scheduled game receives one point.

Having Fun	That is what this tournament is all about. Win or lose, good dice or bad, thank your opponent and be a good sport. Have fun and may you never roll boxes while on the bar.

Swiss Tie-Breaks

Tie-Breaks for the Swiss Mode

Tie-Breaks are used to rank players within point groups. In other words to break ties between players on the same score. The following systems are most commonly used in Swiss tournaments :

For the GoL Tournament, here are the selected Methods in order : 2, 1, 3, 4, 8, 7.

1. Buchholz
This is the sum of opponents' scores. The idea is that the same score is more valuable if achieved against players with better performances in a given tournament.
Looks like an ideal tie-breaking method and has been used since the Swiss system was invented.
However it has some weaknesses which are addressed by other methods (see Median-Buchholz, Progress, Berger below).

2. Median-Buchholz
Same as above but after leaving out the highest and the lowest scoring opponents. Swiss Perfect allows configurable number of highest and lowest scoring opponents to be left out (0,1 or 2)
Its idea is to eliminate distortions in Buchholz values caused by taking into account games against run-away winners and bottom placed players.

3. Progress
Calculated by adding points from a progress table eg if your scores were: Win, Loss, Win Draw then your progressive scores are 1, 1, 2, 2.5 and your Progress tie-break value is 6.5
This is an attempt to put a higher value on scores which were achieved by scoring better in the initial rounds than by finishing from behind. It is common knowledge that the latter is usually much easier to achieve.
The problem is that the order of the Progress tie-breaks is known before the last round (last round scores will change the actual value but not the order within a point group). This may encourage some undesirable tournament "tactics" in the last round.

4. Berger
This is calculated by adding scores of the opponents who were beaten by a given player and half the scores of the opponents who she drew with.
This has been adopted from round-robin tournaments and is usually used as a secondary method.

5. Number of Wins
Calculated by adding a point for a win and nothing for a loss or a draw.
Intended to discourage making quick draws. Popular in 70's and early 80's (particularly in round-robins). These days hardly justified.

6. Opponents' Rating Sum
Sum of the opponents' ratings. Uses the ratings ie presumed pre-tournament strength of the opponents rather than their performance in a given tournament. Also has the same problem with the last round as 'Progress'.

7. Minor Scores
The difference of minor scores FOR and AGAINST. An example of usage of minor scores is Othello (Reversi) where a minor score like 50-14 means that the winner finished with 50 pieces on the board and the loser with 14. Another example is a chess team tournament where the winning team receives 2 points, the losing team 0 as the main score and the sum of board scores eg 4.5 to 1.5 in a 6 board match is the minor score. Yet another example is goal difference in football / soccer.
Using minor scores as a tie break means that a player with a higher difference of the the FOR and AGAINST minor scores is ranked above the one with a lower difference. If a difference is identical then the one with greater value of minor score FOR is preferred. For example 120-100 is better than 90-70.

8. Brightwell
This tie-break is used in Othello (Reversi) and combines Buchholz with Minor Scores. It is the value of the Minor Scores FOR (in case of Othello this is the number of pieces the player scored, disregarding the number of pieces the oponents had) plus a configurable coefficient multiplied by the sum of opponents' scores (Buchholz).
