Stool of repentance (also called "Accusations") is a parlour game for children and adults.
[1][2] One of the group (the "victim") leaves the room, and the rest say or write all sorts of things about them.
The "victim" is called back to sit on the stool, and one of the players begins to tell or them the different charges that were made against them.
If, however, the "victim" is unable to guess correctly, they must leave the room again and fresh charges are made against them.
The game almost certainly takes its name from the old Scottish church custom of the same name.
