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 Merchant’s Room on 1F of the Castle Dimitrescu.
In order to attempt the puzzle, you will first need to obtain the Flower Swords Ball, which can be found on the northwest side of Opera Hall (2F) in a wooden chest. Insert this ball into the circular hole. This will start a mini game in which you need to guide the ball into the tower with a red flag in the middle of the castle. After you complete this task, you’ll be rewarded with a Crimson Skull. You can in turn sell this to Duke for a good chunk of change. For us it was 8,000 Lei.
