For the Get the Ball Rolling trophy in Resident Evil Village, you will need to solve a labyrinth. This labyrinth can be found in the shed behind the windmill with a save point in it, which is south of East Old Town on the way to the Reservoir (see below).
In order to attempt the puzzle, you will first need to obtain the Mermaid Ball, which can be found in a small box on a shrine near Moreau’s Lab east of the Reservoir (see below).
Insert this ball into the circular hole. This will start a mini game in which you need to guide the ball into the glowing spot at the end. After you complete this task, you’ll be rewarded with a Chartreuse Skull. You can in turn sell this to Duke for a good chunk of change.
