Somewhere under the sand, a masterpiece is waiting. Dig it up, scratch away the centuries, and hang it in YOUR museum. SCRATCH & RESTORE Every artifact arrives caked in dust, rust, and mystery. Scratch the grime away — gently! — with the right tool for the right spot. Brush the dust, chisel the crust, swab the tarnish, polish the gold until it glows. Nail it and the piece comes out gallery-grade. DIG FOR TREASURE Send your crew to Ancient Egypt, the Gem Fields, Greece, the Maya, Rome, Dynastic China, and the Inca. Every dig brings something back. Go deeper for rarer finds — but deeper pieces are fragile, and a careless thumb can shatter history. CRACK GEODES OPEN Plain rocks from the crystal canyons hide amethyst, agate, and opal inside. Find the fault line, load your strike, and split them clean. BUILD YOUR MUSEUM Every restored piece goes on your wall. Fill the collection, earn your Reputation, and open the Grand Exhibition hall by hall — plaques, crowds, and your name over the door. DAILY TREATS The morning post brings a scratch-off raffle ticket every day. The Curator's telephone rings with paying jobs. Come back tomorrow — there's always something on the bench. MUSEUM PASS Try it free for 3 days: no ad breaks, a second raffle ticket every morning, every dig insured, and every NEW museum wing the day it opens. Grab your brush. History isn't going to restore itself. Museum Pass is an auto-renewing subscription: $4.99 per week or $14.99 per month, starting with a 3-day free trial. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless you turn it off at least 24 hours before the current period ends.
