Question: What is the single best-selling toy of all time?
Answer: The Rubik’s Cube. As of 2026, the official count from the Rubik’s brand and industry sources puts authentic cube sales at more than 450 million. Some analysts believe that once you factor in unofficial “speed cubes” and clones, the number of 3x3x3 puzzles in circulation could be double that. That works out to roughly one Rubik’s Cube for every 17 people on Earth, a level of market penetration no other standalone toy can touch.
