Game rules 2019

2019-06-14 09:00

Windmill is all about bringing the most well organised, sustainable, high level and high fun Ultimate Frisbee festival in the world. And although we believe that the spirit of the game is the most important thing within our community, we can’t go without a clear set of rules. Rules, knowledge and use is the first item on every spirit form so we like to pay some attention to them.

For those familiar with windmill, the biggest noticeable change this year is the removal of the cap +1 rule!!! Previous years after time was over, teams would finish the point, add 1 point to the highest score and keep on playing until one of the teams would have reached this score.

We found this lead to games that would be exciting all the way to the very last pass as there was always a chance to come back and take the game. However, it could also lead to very long games - spoiling over far into the next time slot.

So, due to good feedback and after lengthy discussions in our scoring team, this year we will play with a hard time cap. After the time is over, finish the point and the game ends. Yes that means a draw is possible! Our system only cares about if you performed better or worse than our prediction. There will be an exception of course in the brackets and the finals.

Here we have the rule that when time is over and the score difference is less than 2 (so either 0 or 1 point difference) then the traditional cap +1 on the highest score will be played.

Below you can find all the tournament rules. In case anything is unclear and you have questions, send us an email

Rules and Format 2019

  • The latest WFDF 2017 rules apply at this tournament. You can find the rules at the WFDF site.

  • The WFDF 2017 Additional Championship Game and Event rules do NOT apply at Windmill. Instead the Windmill Tournament rules below apply.

Game times

  • Open, Mixed & Ladies games are to 15 points within 90 minutes time-slots. Five minutes before the end a time slot you will hear the ‘time-is-over’ jingle. Play out the current point and the game is finished. Even if the score tied. In the brackets and final if the difference is less than 2 (so equal or 1 point difference) than there will be played until a cap +1 on the highest score

  • Finals are also 90 minutes time-slot

  • All games have a two-minute mirror halftime at 8 points. The second half is started with initial elections (whether to receive or throw the initial pull, which end zone to defend, and which end zone decides the gender ratio in mixed) switched.

  • Each team has 2 two-minute time-outs per game, which can be taken at any time before the 'time-is-over’ jingle (i.e. there are no timeouts in the last 5 minutes of a time-slot).

Windmill Tournament Rules 2019

  • Teams are expected to arrive on time. Game can start as soon as each team has a minimum of 5 players (WFDF rule 5.1).
  • Players must not use any form of electronic communication devices  to communicate with other players or team members during play.
  • Players must not wear anything that is dangerous to other players, or could damage the disc. Metal studs are considered dangerous.
  • Players must not wear anything that gains an advantage by substantially enhancing  physical presence of the player. Gloves are allowed.
  • Players are prohibited from applying any substance to their hands, for the purposes of enhancing grip, which can transfer to the disc during the course of play
  • Players, substitutes and team officials must not use any equipment that amplifies their voices.
  • The Windmill organisation reserves the right to suspend players for one or several games due to substance abuse.
  • Players are not allowed to be under influence of any (in the netherlands) illegal substances during play. Also players who are unfit to play could be removed from the game.


Mixed format (4/3):

We play normal 4/3 mixed using Ratio B: “end zone decides” rule (WFDF rule A7.3): At the start of the game, after the first disc flip, an additional disc flip happens with the winner selecting which end zone is “End zone A”, with the other end zone becoming “End zone B”. At the start of each point the Team that is at End zone A must choose the gender ratio. This process applies for the first half. For the second half, at the start of each point the Team that is at End zone B must choose the gender ratio. The choosing team must be clear and quick about which it will be so the opposite team  has time to match and strategise before the next pull.

All players can choose which side of the gender ratio they are eligible for as long as it doesn’t lead to unsafe or unfair situations.

Swiss Draw

The Swiss Draw format ensures that teams are ranked quickly according to their real strength and play close matches against opponents of similar strength. Windmill is proud to have successfully run this format for years.

Playoff Brackets

The tournament starts by completing five rounds of the Swiss Draw format - using the power ranking method - in order rank the teams. Following five rounds of play, two divisions are created; division A contains teams ranked 1 through 8 (inclusive) and division B contains teams ranked 9 onward. The top 8 teams (division A) move on to complete in a standard playoff bracket format, playing quarter finals, semi finals and finals. Teams in division B continue with three further rounds using the Swiss Draw format (continuing with Swiss Draw has the advantage that the lower teams are likely to play new opponents).
