Cross sums daily mail

A classic!

The Cross Sums puzzle, also known as the "Classic Sudoku" or "Number Place", is a popular puzzle that has been featured in The Daily Mail and many other newspapers and magazines around the world.

Here's how to play:

The Rules:

1. The puzzle consists of a 9x9 grid, divided into nine 3x3 sub-grids or "regions".
2. Some numbers are already filled in, while others are blank.
3. The goal is to fill in all the blank cells with numbers from 1 to 9, such that each row, column, and region contains each number only once.

The Clues:

1. The Daily Mail typically provides a set of clues, usually in the form of "cross sums", which are the sums of the numbers in each row, column, and region.
2. The clues are usually written in the form "Row 1: 15", "Column 3: 8", or "Region 2: 12", indicating the sum of the numbers in that row, column, or region.

How to Solve:

1. Start by focusing on one region, row, or column at a time.
2. Use the clues to figure out which numbers can go in each blank cell.
3. Look for cells that only have one possible number that can fit, and fill it in.
4. Repeat this process until you have filled in all the blank cells.

Tips and Tricks:

1. Start with the easiest clues first, such as rows or columns with only one or two blank cells.
2. Use elimination techniques to figure out which numbers can't go in each cell.
3. Look for "naked pairs" or "hidden pairs" to eliminate possibilities.
4. Use "X-Wing" and "Unique Rectangles" patterns to eliminate possibilities.
