The World's Largest Sudoku Puzzle: Win £5000

Well done Sudoku enthusiasts! You've spotted that our record-breaking Sudoku grid has more than one solution. The hillside grid was planned for the live show format, but all correct solutions will be accepted into the prize draw for the cash prize of £5,000.

Constructed on an enormous hillside near Chipping Sodbury, just off the M4, The World's Largest Sudoku Puzzle is a significant piece of public art, measuring 275 ft by 275 ft. Up to a million cars are expected to pass by the giant puzzle in the next seven days and, with Sudoku mania gripping the nation, Guinness World Records have recognised this as The World's Largest Sudoku Puzzle.

To celebrate this fact Sky One is offering one lucky Sudoku enthusiast the chance to win £5,000, by solving this particularly fiendish grid and entering our online competition.

To enter, simply print off the grid, complete it correctly and send the finished grid to:
