How to play

Consecutive Sudoku puzzle solution
A Consecutive Sudoku is based on the same rules as a standard Sudoku grid. However, you will also find a thick grey line separating some cells, the two cells either side of this separating line are consecutive, i.e. there is only a difference of 1 in their values.
This is an example of a completed Consecutive Sudoku puzzle. You will notice that every thick grey line has two numbers either side that are only different by 1.
Consecutive Sudoku puzzle
This is a Consecutive Sudoku starting grid, and we can fill in the hilighted cells. The easiest cells to start with in a Consecutive Sudoku are those that are 'consecutive' with a 1 or a 9 - there is only one possible solution in this situation, either a 2 or a 8 respectively. We can use this to fill in the top and bottom highlighted cells.
The highlighted cell to fill in on the center-right is a little trickier to fill in. We can use the normal rules of Sudoku to eliminate 1, 2, 3, 4, 6, 7, and 8. This leaves us with just 5 and 9. We also know that this number be must be consecutive with 6, i.e. 5 or 7. This allows us to fill this cell in with a 5.
