They're quite simply out of this world!
These cleverly-designed ball puzzles provide a challenge that defies your expectations. The cover flips open to reveal a classic maze puzzle... but one in which each steel ball appears to have a mind of its own. Tilt it down and the ball goes up not down!
Simultaneously confusing yet engaging, each puzzle can be played in two ways: Conventionally with the lid open or upside down, where the gravity appears to have been reversed!
