The games are held every four years in staggered summer and winter events consistent with the current Olympic Games format, though in reverse order with the Olympic Winter Games held in leap years instead of the Summer Olympic Games. The first summer version was held in Singapore from 14 to 26 August 2010 while the first winter version was held in Innsbruck, Austria from 13 to 22 January 2012.
