Summer League follows the current WFDF rules with a couple of changes (most notably we play 5-a-side instead of 7-a-side). You can find the current WFDF rules here under the Ultimate section: http://www.wfdf.org/index.php?page=rules/index.htm#ultimate

The rules for Summer League are summarised below:

• 5-a-side
• Mixed: we're introducing a loose mixed rule this year, to try and encourage more women to play. Teams are expected to play with a 4:1 gender split (or higher) if possible. The ratio to be choosen by the receiving team. We understand that some teams may find it difficult to play be this rule. If both captains agree, this rule can be overruled.
• game length: 42min or first to 15points. 2min half-time after 20min. Games will finish 42min after they start.
• finish the point: when time goes during the point, check the disc (i.e. pause the game and acknowledge time has gone), then play on 'til the next point is scored, then finish the game. There's no additional points cap.
• pitch size: 45m x 25m with 15m deep endzones. Brick mark at 12m forward of the endzone line.
• 10 second stall count
• 1 timeout per team per half. Timeouts are 2 minutes long.
• Droppable pulls: pulls can be dropped without resulting in a turnover. Deliberately dropping the pull with the aim of advancing the disc does result in a turnover.

Summer League also uses the BULA/WFDF Spirit scoring system. Score sheets are available here: http://www.wfdf.org/rules/SOTG_v2010_EN.pdf
