1. The pitch is full size.

2. Each team has no more than 12 players in the playing area during play.

3. A team may nominate up to eight replacements. However, if you have any additional players, please bring them along to support other teams with lower numbers.

4. A team may replace any number of players during a match at any time.

5. Scrums will be arranged with 6 players per team.

6. Scrums will become uncontested if either team cannot field a suitably trained front row (or if the referee so orders).

All other rules are as per RFU Regulation 15, Appendix 9.
