The Yomega Brain, introduced in 1984 and protected by U.S. Patent #4,332,102, was the toy industry’s first centrifugal-clutch auto-return yo-yo. When the yo-yo’s spin slows below a threshold, the clutch engages and automatically winds the string, returning it to the player’s hand. The Brain became one of the best-selling yo-yos in history and established Yomega as a household name worldwide. It remains in production today and serves as the definitive entry point for beginner players.
