Rules of 'Quadruple Sudoku'
Place numbers in the grid such that each row, column and 3x3 box contain the numbers 1 to 9. Each set of four small numbers in the intersection of two lines indicate the numbers that are in the four adjacent cells.
Quadruple Clue Sudoku was invented by Henry Kwok. The variant was named by Serhiy Grabarchuk when it was published on his AgeOfPuzzles website in 2006. Please refer to http://www.ageofpuzzles.com/Collections/QuadrupleClueSudoku/QuadrupleClueSudoku.htm
Henry Kwok was also asked to create the variant for the Second World Sudoku Championship 2007 in Prague.
