PEKING -- The supply can't meet the demand in China for 'Magic Cubes,' the popular name for Rubik's colorful cube puzzles.
The official Xinhua news agency said Peking's 8 million people have so far purchased 300,000 Rubik Cubes and the demand still is going strong.
The New China Children's Shop, the biggest in the capital, has sold more than 11,000 cubes since December and the manager declares, 'Supply still falls short of demand.'
'The shortage will continue at least until May,' Xinhua reported, quoting the city's commercial authorities.
Books explaining and giving solutions to the cube puzzle have become best sellers, the agency said.
People young and old play with the cube 'on buses or in streets, parks and other public places,' it said.
