3s League Frequently Asked Questions (FAQ)

3s League is Orange County's first dedicated youth 3-on-3 basketball league for boys and girls ages 9U–14U. Inspired by official FIBA 3x3 rules, our league focuses on skill development, confidence, and fun in a fast-paced, half-court format where every player gets more touches, more shots, and more learning opportunities.

3x3 basketball is played on a half court with one hoop, giving players more ball-handling, shooting, and defensive reps every game. It's faster-paced, promotes teamwork and basketball IQ, and helps players develop skills they can translate directly to 5-on-5 play.

Games follow FIBA 3x3 rules with slight youth-friendly adjustments. All rules can be found here: 3sleague.com/rules
