Study the gallery for 8 seconds: every piece, its topper, its pattern, which way it faces.
The curtain drops and your crew lifts a few originals. Some replicas in the crate are near misses.
Drag a replica onto each empty plinth, tap it to turn it. 60 seconds a room.
The guard checks every swap. Three slips and the alarm goes.
A made-up gallery and made-up art. Just a memory game.
