Knucklebones is a traditional game that originated from the ancient practice of using small bones from the ankles of animals, often sheep or goats. Players would toss these bones, which are typically shaped like cubes, and score points based on how they land. The game has been played in various cultures around the world, often with different rules and variations. In addition to being a game, knucklebones also refers to the actual bones used in play. These bones can be made from materials like wood or plastic in modern versions. The game is similar to jacks, where players aim to collect pieces while bouncing a ball.
