Premium Challenge
ONE OF A KIND
A Tough Nut to Crack
Complete the launch trio of genuine giant nut Big Things.
Premium Challenge Library
The challenge exists and its Big Things remain part of the free field guide. Premium unlocks the curated qualifying set and challenge gameplay.
Premium never changes access to the underlying Big Thing listings, safety information, navigation facts or your Visits. If Premium becomes active later, existing Visits – including Visits made while membership was inactive – are re-evaluated automatically.
About Premium
PREMIUM DEFINITION
The qualifying set and your exact progress stay private until Premium is unlocked.
This browser receives neither the curated member list nor a personal progress total for a locked Premium edition. That same boundary prevents listing pages and Explore from revealing which Big Things belong to it.

Why this challenge exists
Edition 1 is the exact published, ordinary-eligible true-nut set: Woombye macadamia plus the Kingaroy and Tolga peanuts. Nut-and-bolt objects and peanut-butter packaging are excluded.
Edition 1 · published 28 August 2026
Challenge definitions are versioned. If later research changes a qualifying set, a new edition is published – an achievement you have already earned is never taken away.
