For individual performances, a gymnast manipulates one or two pieces of apparatus (double rings, stick, clubs, rope) to demonstrate their skill at apparatus handling, throws, and catches as well as the difficulty of the tumbling. The gymnast must work the entire floor area whilst showing continuous flowing movement. The permitted time for individual events is between 1 minute 25 seconds to 1 minute 33 seconds. During a competition, each individual gymnast performs four separate routines, one for each apparatus. Points are based a 20-point scale. The first 10-point scale measures composition (difficulty) based on technical value, variety, harmony between music and movements, and originality, while the execution of performance is a maximum of 10 points. The individual scores of all four routines for each gymnast are then added up to decide the all-around winner.
