"Product code:IQ-1057AU"Summary: "Take your Sudoku addiction to the next level! The Sudoku Cube features numbers instead of colours, allowing you to twist and turn to complete the Sudoku challenge. Each side will present a different challenge as you align the numbers 1 to 9 on each side. Just like regular Sudoku, the same number cannot appear more than once on any one side! Created by the MENSA team, the cube is accompanied by bonus brainteasers to help you get into the puzzling mood."--Australian Gepgraphic website, viewed 24th July, 2018.
