U18 Tournament Rules

1. Basket Height

The basket height is 305 cm.

2. Game Ball

A size 7 basketball will be used.

3. Jump Ball Rule

Possession is determined by the opening jump ball. After that, alternate possession is used. The team that does not gain control from the opening tip will receive the next possession. For held ball situations, alternating possession applies.

4. Age Eligibility

U18: Born on or after January 1, 2008, and those who remain 18 at the time of this tournament. U15 players may participate in U18 competitions. However, U18 players are not allowed to participate in U15 competitions.

5. Game Duration & Breaks

Game Duration: Each game consists of four 8-minute quarters. Teams switch baskets at the start of the 3rd quarter. Overtime lasts 2 minutes.

Breaks: 1 minute between quarters and 2 minutes at halftime. The clock will stop on every dead ball.

6. Timeouts

Teams may request a time-out during dead ball situations or after an opponent's basket. Requests must come from bench staff at the scorer’s table—not from players. In the first half, teams can request two timeouts, three timeouts in the second half, and one timeout per overtime period. Each timeout lasts one minute. If players fail to return promptly after a time-out despite repeated reminders, the coach may be assessed a technical foul for delay of game.

7. Substitution Rules

All players are encouraged to participate; no restrictions on playing time or number of quarters. Substitutions may occur:

1. During dead ball situations.

2. After an opponent’s basket in the last 2 minutes of the 4th quarter or during overtime.

Substitutes must report to the scorer’s table and enter only with referee approval. If a team is left with only one player, the game ends and the team forfeits 0–20. A replacement for a disqualified player (fouled out or ejected) must enter within 30 seconds. Otherwise, the team will be penalized for delay of game.

8. Team Fouls & Penalties

When a team commits 5 or more fouls in a quarter, the opponent receives two free throws. Players foul out upon their 5th personal foul. No free throws are awarded for offensive (team control) fouls. Fouls in overtime are counted as 4th quarter fouls. Team technical fouls do not count toward team fouls; the opponent is awarded one free throw.

9. Defensive Rules

Both full-court man-to-man and zone defenses are allowed.

10. Offensive Rules

Every game must have a winner; unlimited overtime periods allowed. If a player is fouled while shooting and the shot is made, they are awarded one additional free throw. 24/14-second shot clock applies, along with standard 8-second backcourt, 5-second closely guarded, and 3-second lane violations.

11. Pre-Game Check-In

Only registered players are allowed to participate in the competition. No additional players can be added at the last minute. Any violation will result in a forfeit with a 0:20 score. Players must present the personal EasyCard issued by the event organizer. If a team has fewer than 5 players before the game starts, a 10-minute countdown will be activated. If the team is still short of players at the end of the countdown, the game will be forfeited. If both teams fail to show up, the match will be canceled. Each team can register up to 15 players.

12. Uniform Rules

Each team must prepare two colors of uniform. The team listed first wears light-colored jerseys and sits on the left of the scorer’s table. The team listed second wears dark-colored jerseys and sits on the right. If a player is not in proper uniform, they may only play with the opposing coach’s consent, and a team technical foul will be assessed. If consent is denied, the player cannot participate.

13. Remarks

Ice bags and wraps provided at the venue are for emergency use only during matches. Teams should bring their own icing supplies. Unless otherwise specified, the tournament follows 2024 FIBA Rules. The organizer reserves the right to interpret, amend, and finalize all tournament-related matters.
