"It's also about getting travellers to trust strangers in strange lands and about actively participating in sight-doing scavenges, not just passive sight-seeing," the organisation's website says.
The champions are decided on points scored during the stopovers.
Defending their title next April will be two American lawyers.
The 2012 early-bird entry fee, available until December 16, is US$9900 (NZ$13,009) per person and US$10,900 per person thereafter.
The price takes care of all international airfares during the competition, first-class hotels, 40 per cent of meals and special-event gear.
No prize money is offered but the winning team receives free entry into the 2013 hunt, and special prizes are awarded along the way.
Then there's the title of "world's greatest travellers" - and bragging rights.
The event aims to raise money for international causes and natural disaster victims through its non-profit charity, the GreatEscape Foundation.
