The GrandSlam competition uses a revolutionary judging system where the judges no longer compare one couple with the others on the dance floor. Rather, they focus on each couple individually and award points on an absolute scale for the quality of dancing. Combining athleticism and artistry, the 12 best dance couples perform Latin and Standard styles of dance, from the samba, cha cha cha, rumba and paso doble to the waltz, tango, slow foxtrot and quickstep.
