Competitor’s choice". Skaters have "complete freedom" to select any free skating elements they choose; the sum of the elements make up an entire free skating program. All the elements must be linked together by connecting different steps and other free skating movements. Skaters must use the entire ice surface. Forward and backward crossovers, however, do not constitute connecting steps. If a skater performs more elements than what is prescribed, only the first attempt, or the allowed number of attempts, is counted in their final score. A well-balanced free skate for junior and senior men and women single skaters must consist of the following: up to seven jump elements, one of which has to be an Axel jump; up to three spins, one of which has to be a spin combination (one a spin with just one position, and one flying spin with a flying entrance); only one step sequence; and only one choreographic sequence. Skaters can execute up to three jump combinations or jump sequences in the free skating program and can consist of the same or a different single, double, triple, or quadruple jump. One jump combination may consist of up to three jumps, while the other two jump combinations can consist of up to two jumps. Any double jump, including the double Axel, cannot be included more than two times; i.e., as a solo jump or as part of a jump combination or jump sequence. Only two types of triple and quadruple jumps can be executed twice or attempted more than twice. Jumps are judged in the order of execution. The ISU requires that all spins "must be of a different character". Skaters must include a required number of revolutions in their spins: at least ten spins in their spin combinations and six revolutions for both their flying spin and the spin with only one position. Judges count the minimum number of required revolutions from the entry of the spin to, other than the wind-up in flying spins and spins with just one position, its exit. A change in foot is optional in the spin with spin combinations and spins with only one position. Skaters have complete freedom in the selection of the kinds of step sequences they want to execute. They can include jumps in their step sequences, but they must fully utilize the ice surface. The ISU also states about step sequences: "Step sequences too short
