The purpose of this study was to examine skill levels and performance patterns of regular players of pick-up basketball games. By a survey, 65 participants were identified as regular players and participated in the study. An observational instrument used to analyze game performance of the participants was developed and both content and construct validity of the instrument were established. Results indicated that the chest pass, overhead pass, bounce pass, and one-hand pass were frequently used passing skills; forward dribble, crossover dribble, and change-of-pace dribble were frequently used dribbling skills; and the jump shot, set shot, and layup were frequently used shooting skills. Hands up, jump and reach, two-hand catch, and box out were frequently observed in the games. The offensive tactics frequently observed were straight cut, straight drive and layup, and set screen, and the defensive tactics were steal intent, pressuring the dribbler, block intent, hand up, and defensive slide. The findings may help physical education teachers decide what skills and tactics should be taught in a basketball unit so that students can enjoy playing pick-up games.
