Starting at the State Library Victoria on Swanston Street, you'll open the Explorial app, enter the 6-digit game code that you received by text and Viator chat message, and dive into Melbourne's famous grid. The tour is fully self-guided — no guide, no fixed start time, just your group and the city. The Majorca Building glows Spanish-blue in Degraves-side laneway country, a 1920s romantic among the coffee windows. Riddles order a flat white and begin. Flinders Street Station follows — the mustard-yellow icon where 'meet me under the clocks' has arranged a century of rendezvous. Trivia checks the timetables of history. Then AC/DC Lane cranks the volume: street art, stickers and rock pilgrimage in one narrow strip, Cherry Bar legends included. Around two hours of arcades and alleys. The leaderboard is announced — for those about to win, we salute you.
