Leonardo da Vinci is in trouble. Every morning he returns to his fresco in Santa Maria delle Grazie to find the same thing: the snake from the Sforza coat of arms has been removed. One night, he waits in the dark, and catches the Devil himself at work. A deal is struck, and you are Leonardo's chosen student. To save the Last Supper, you must outwit the Devil across 10 real Milan locations in this self-guided outdoor escape game. Download the free Questo app, head to Piazza del Duomo, and start anytime — no booking required. The route takes you through the streets Leonardo actually walked: from the Duomo (where he once proposed his own architectural designs) to the Ambrosiana Library (home to his original Codex Atlanticus), the crypt he described as the centre of ancient Milan, and the vineyard Ludovico il Moro gave him as payment for painting the Last Supper. Solve riddles, decode clues at real landmarks, and discover the Milan that shaped a genius. Suitable for all ages.
