Sudoku 4×4 is a smaller version of the popular number puzzle game Sudoku. It is played on a 4×4 grid, which is divided into four 2×2 sub-grids. The objective of the game is to fill in the grid with the numbers 1-4 in such a way that each row, column, and sub-grid contains all of the numbers 1-4 exactly once.

Unlike the larger 9×9 version of Sudoku, which is the most common, the 4×4 version is simpler and can be solved more quickly. It is often used as an introductory version of the game to help beginners understand the basic rules and strategies of Sudoku.

Difficulty levels for the Sudoku 4×4 puzzles on this page are:

Easy, Medium, and Hard

Higher difficulty levels (Medium, Hard, Extreme) contain fewer givens, or clues, and are therefore more difficult to solve. All puzzles have a unique solution. All are solved by using logical progression and process of elimination - no guessing should be used or is needed. Solve for 'what must be' combined with 'what cannot be'.

• The game is played on a 4×4 grid, which is divided into four 2×2 sub-grids.
• The objective of the game is to fill in the grid with the numbers 1-4 in such a way that each row, column, and sub-grid contains all of the numbers 1-4 exactly once.
• Each row and column must contain one of each number from 1 to 4.
• Each sub-grid must contain one of each number from 1 to 4.
• The initial board will contain some numbers already filled in. These numbers cannot be changed.
• To solve the puzzle, you must use logic and deduction to figure out which numbers belong in each empty cell.
• The puzzle is solved when all empty cells have been filled in and the rules above have been followed.

1. Start by scanning the puzzle: Look at the puzzle and identify any numbers that are already filled in. This will help you to identify which numbers are missing and which numbers have already been used.
2. Focus on one sub-grid: Pick one of the four sub-grids, and start filling in the numbers 1-4 in the empty cells. Make sure that each number is used only once in the sub-grid.
3. Check for duplicates: As you fill in the sub-grid, make sure to check for any duplicates in the rows and columns. If a number is already present in a row or column, it cannot appear again.
4. Move to the next sub-grid: Once you have filled in one sub-grid, move on to the next one, and repeat the process.
5. Use the process of elimination: As you fill in more cells, you may start to see patterns and possibilities for other cells. Use the process of elimination to cross off numbers that cannot go in a particular cell, based on the numbers that are already present in the row, column, or sub-grid.
6. Keep filling in cells: Continue filling in cells, one sub-grid at a time, until you have filled in all the cells in the puzzle.
7. Double-check your work: Once you have filled in all the cells, double-check your work to make sure that each row, column, and sub-grid contains the numbers 1-4 exactly once.

By following these steps, you should be able to solve most Sudoku 4×4 puzzles with ease. As you gain more experience, you may start to develop your own strategies and techniques for solving the puzzles more quickly and efficiently.

• Start with the sub-grids: Since Sudoku 4×4 has smaller sub-grids than the 9×9 version, it can be helpful to start by filling in each sub-grid with the numbers 1-4 before moving on to the rows and columns. This can help you to identify which numbers are missing and which numbers have already been used in each sub-grid.
• Look for unique numbers: In Sudoku 4×4, each row, column, and sub-grid must contain the numbers 1-4 exactly once. If a number is already present in a row or column, it cannot appear again. Therefore, you can use this to your advantage by looking for numbers that are already present in a row or column and using that information to eliminate possibilities in other cells.
• Use the process of elimination: Once you have identified which numbers can and cannot be used in each cell based on the rules of Sudoku, you can use the process of elimination to figure out which number belongs in each cell. If there is only one number that can go in a particular cell, you can be confident that it is the correct number.
• Practice: As with any puzzle game, practice is key to getting better at Sudoku 4×4. The more you play, the more familiar you will become with the rules and strategies of the game, and the easier it will be to solve increasingly difficult puzzles.
• Take your time: Sudoku 4×4 is meant to be a challenging but enjoyable game, so don’t rush through it. Take your time, and don’t be afraid to use pencil and paper to keep track of your progress. By staying focused and patient, you’ll be able to solve even the most difficult puzzles.

• Even-Odd Sudoku 4×4: In this variant, instead of using the numbers 1-4, the puzzle is filled with even and odd numbers. Each row, column, and sub-grid must contain two even numbers and two odd numbers.
• Diagonal Sudoku 4×4: In this variant, the numbers 1-4 must appear once in each row, column, and diagonal line of the grid.
• X Sudoku 4×4: In X Sudoku, the numbers 1-4 must appear once in each of the two main diagonals of the grid, as well as in each row and column.
• Alphabet Sudoku 4×4: In this variant, the grid is filled with letters of the alphabet instead of numbers. Each row, column, and sub-grid must contain the letters A, B, C, and D exactly once.
