Basketball - Men’s 4's (Officiated)

There is only one format of Men’s Basketball under JAM and Nation Leagues rules. It is described in its entirety below.


Game Time

All Basketball games are approximately 40 minutes in length, including two (2) 20-minute halves and a 2-minute halftime. Please arrive early to ensure you get the full use of your allotted court time. Regardless of when your game begins your game will always end on time to allow the succeeding games to begin at their scheduled time.

Time Keeping: The on-site Nation Leagues and JAM scorekeeper and official will be keeping track of time and the score. Please refer to the on-site score clock to see the remaining time in each half.

  • Games are 2 x 20-minute halves.
  • Time is stopped during free throws.
  • Game will be stop time in the last 2 minutes if the game is within 8 points.

Defaults: A default will occur if any team cannot field a squad by 10 minutes after the official start time. A team must have a minimum of 4 people. Defaults are beyond the control of the league, and there will be no refunds for defaults.

Timeouts: Teams are allowed 1 timeout per half (and unused timeouts do not carry over to the 2nd half). Timeouts are 30 seconds in length. Any player on or off the court is eligible to call a timeout, as long as all other FIBA requirements for calling a timeout are met (i.e dead ball, possession)



Teams are comprised of four (4) players on the court at once.

Defaults: A default will occur if any team cannot field a squad by 10 minutes after the official start time. A team must have a minimum of 4 people. Defaults are beyond the control of the league, and there will be no refunds for defaults.


Playing Area

For all formats of Nation Leagues and JAM Basketball, the net and court will always be set up for you when you arrive. All gymnasiums will vary in size, so the dimensions of the playing area will vary per location.

Last game of the night must change and leave ASAP, due to time restraints with the school permit.


Equipment/Set Up

For all basketball leagues, Nation Leagues and JAM basketballs will be available on site.

Whether you use a Nation Leagues or JAM provided ball or a personal one, the final determination should be made the team captains and official prior to the start of the match. Both captains and the official must agree on which ball they choose to use for their match. If no consensus can be made then teams will use a provided JAM or Nation Leagues basketball.



Teams are required to bring both light and coloured shirts to every game. Team colours are posted on the JAM website in your schedule. If two teams have the same colour the team captains should contact each other to ensure that each team knows what colour to wear.

Defaults: There is no default for players that don’t wear the right colour. However, that player must do everything they can to ensure it’s not confusing for the opposition. Whether this means wearing a pinny, a hat, a teammate’s shirt, etc. Under no circumstances can a player purposefully deceive the opposition.

Uniforms with #'s are NOT mandatory. However, since statistics are being kept for your team, we strongly recommend that you wear shirts with #s so that specific players can be identified with accuracy.
