THE PUZZLE THAT'S GRIPPING THE NATION
HOW TO PLAY
You must fill in every empty square in the Sudoku grid. There’s no right way of going about this, but there is only ever one solution. The big grid is split into nine mini-grids. There are nine rows running left to right and nine columns running down. In every row, you must have each of the numbers 1, 2, 3, 4, 5, 6, 7, 8 and 9. These can be in any order. The same applies to columns and mini-grids: place every number 1 through 9 in each column and in each mini-grid.
GRID 1: BEGINNER
GRID 2: ADVANCED
