6 players are allowed on the field at any one time
At least 2 females on the pitch at all times.
A team can play a legal game with 4 players, with 1 female.
Teams may have as many players in their squad as they want.

Substitutions can be continuously made at any time from one side of the field. The substituting players must make contact with each other behind the sideline.

A game is played in two, 20 minute halves separated by a short half time. The referee maintains a running clock throughout each half. The clock will only be stopped for injuries.

Play starts and restarts at the centre with a “tap”. This is performed by moving the ball on the ground with the foot, free from the hands, and then picking it up. Penalties are performed by the same procedure. On both a re-start and penalty the defending team must retreat at least 10 metres.

Check out this rugby training guide here.

A try is scored by grounding the ball on, or behind, the try-line. One point is awarded in men’s, women’s and mixed leagues.

A legal touch is on any part of the body, clothing and ball. A player must claim a touch by raising a hand and shouting, “Touch”. The referee is the sole judge of the touch and has the discretion to overrule a claim. (Play to the whistle).

When touched, the player in possession must place the ball on the ground at the exact point of the touch. Play is re-started by stepping over the ball. It can be controlled with a hand or foot. This is known as a ROLLBALL. The ball may not roll more than a metre. A player may not perform a rollball unless touched.

The player picking up the ball (the ‘dummy-half’) may run, but if touched a changeover occurs. The dummy-half may not score and a changeover (tap) will be awarded if this occurs.

After 6 touches possession changes. The attacking team begins play on the “first down”, starting with a roll ball.


All defending players must retire more than 5 metres in line with the mark of touch. The defending team cannot move forward until play restarts, nor interfere with play whilst retreating. A restart occurs the moment the ball is tapped or the dummy-half touches the ball at the roll ball. If there is no dummy-half in position (within 1 metre of the mark) defenders may advance from an on-side position.

If the attacking player, when making a quick start, is touched by an off-side defender, play is allowed to continue(playing advantage). If an attacking side gains no advantage, a penalty tap for the first down will be given.

When a rollball is taken within 5 metres of the try-line the defending players must retreat with both feet to behind their try-line before they can make the touch. If a player is touched in the touchdown zone before grounding the ball the touch counts and play is restarted on the 5-metre line. At all times no team may delay the game by deliberately delaying a roll ball.

If the ball is dropped or if a player crosses the sideline before being touched, change of possession will occur. This is by means of a roll ball (from the point where the incident occurs).

A penalty is awarded for the following infringements;
– a forward pass,
– offside play,
– performing a roll ball over the mark,
– claiming a Touch when none was made,
– interfering with the roll ball (running around the ruck)
– passing the ball once touched.
The referee must give the exact mark from where the Tap Ball must be taken. The defending team must retire 10 metres from the mark or behind the try-line.

If the defending team unsuccessfully intercepts the ball or it is intentionally knocked down, the attacking team starts from a “first down” roll ball.

The principle of advantage will be applied.

No obstruction, excessive contact, verbal abuse or foul play will be tolerated – the referee is sole judge. A penalty will be awarded in such cases and a player can receive 2 minutes in the SIN BIN. Serious or continual foul play of any nature will result in the player being sent off without a replacement.  

If your team forfeits a match during the season, the following rules apply:

1st Offense: Loss of game and warning issued.
2nd Offense: Loss of game and staff reserves the right to remove team from playoffs.

If you know in advance that your team is going to forfeit a game, we encourage you to call our office so as to help us schedule your opponent a game.


Teams have until ten minutes past the designated start time to field a full squad (minimum 2 females). If at that time one team is unable to field a full team, it will be up to the staff and the opposing captain to determine what is allowable. They have the choice of making the team play short handed or forcing a forfeit. We always strongly encourage the former, and look to play a game in all circumstances.

The updated standings will be posted weekly, displaying each teams rank within its skill level.


All eligible teams make the playoffs (teams that have not abused any policies are eligible). In certain situations teams at or near the bottom of the standings may not advance to the playoffs. Check with GO MAMMOTH league coordinator to see if this applies to your league.

Playoffs are single elimination.

Ringers used during play offs/finals must be agreed by both sides before the games begin- if a team does not permit another team to use ringers they will have to play short-handed.

Teams may play more than one match per day.

Any questions regarding policies, rules, or eligibility must be addressed before the start of the match.

In order to participate in the league, each participant must sign the team waiver. Waivers are provided and must be completed and handed in no later than the first night of play. Players not present the first week of play will still be required to sign a waiver with our staff before participating.

The idea of GO MAMMOTH is to have fun. We hope that all participants keep that in mind when becoming involved. Although the games may become intense, you still can be competitive while maintaining good sportsmanship. With this said, any behavior deemed unacceptable by staff may result in suspension and/or ejection from a game or the league.

To coordinate and run the league, our refs and/or staff will be available at all times to help the league run as smoothly as possible. If you have questions regarding schedules, policies, rule interpretations, directions to the bar, etc. please ask.
