How to Play X Sudoku

To solve an X-Factor daily Sudoku, every number from 1 to 9 must appear in:

  • Each of the nine vertical columns
  • Each of the nine horizontal rows
  • Each of the nine 3 x 3 boxes
  • Each diagonal arm of the pink X that intersects the grid

Use the mouse to click up (or down) through the numbers 1 to 9 in each square. The small black arrows on each side of the sudoku square tell you whether you are counting from 1 up to 9 (right arrow) or from 9 down to 1 (left arrow).

Using your keyboard, you can type in up to eight practice numbers above the line at the top of each box.

When you have correctly completed a row, column, 3 x 3 box or diagonal, that area fills with colour and any practice numbers will disappear.

About X Sudoku

Sudoku took the world by storm in 2005, quickly becoming the latest puzzle craze. Often referred to as a Japanese number puzzle, in actual fact, Sudoku has a long history with ancient origins. It is thought that Latin Squares, known since medieval times, are the progenitors of the modern grid.

American company Dell published the first contemporary Sudoku in 1979 under the name 'Number Place'. The puzzle soon found a large audience in Japan, and was renamed Sudoku (meaning ‘single number’) by publishing house Nikoli.

Contrary to popular belief, you do not need to be good at maths to solve a Sudoku! The puzzles are based on the principles of logic and recent variants have been created which use systems of letters, shapes or colours instead of numbers.

X-Factor Daily Sudoku is one such variant that adds an extra challenge to the traditional puzzle. The intersecting diagonal arms which give the grid it’s distinctive X shape also require filling with the numbers 1 to 9.

The X-Factor Sudoku puzzles featured on YouPlay are presented by Lovatts Publications, leaders in the industry for over 25 years. With a reputation for exceptional quality, Lovatts X-Factor Sudoku puzzles will provide you with hours of brain-teasing entertainment.

YouPlay X-Factor Daily Sudoku Tips

1. A fresh daily challenge, you start the puzzle with several pre-determined numbers included as givens. These cells are marked and cannot be erased. Each time you start a new puzzle, a different set of numbers will appear.

2. The object of the game is to fill the empty cells with the numbers 1 to 9, with each number only appearing once in each column, row, 3 x 3 box and intersecting diagonal.

3. For each empty cell, you must determine which numbers can be inserted, according to the game rules. In the beginning you may have several options for each cell.

4. YouPlay X-Factor Sudoku puzzles have a space at the top of each cell where you can type up to eight practice numbers that could be correct.

5. As you fill out the different options for each cell, you will find that several cells have only one number option that could be correct, which you can then type inside the cell.

6. Whenever you type in a correct number, you should update the practice numbers for the remaining cells.

7. Repeat this process throughout the whole game and eventually you will complete the X-Factor Daily Sudoku grid.

8. If you get stuck, you can use hints to help solve the puzzle. Click the HINT button once when you require a hint.
