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.

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. If a number is already present in a row or column, it cannot appear again. Look for unique numbers: In Sudoku 4×4, each row, column, and sub-grid must contain the numbers 1-4 exactly once.This can help you to identify which numbers are missing and which numbers have already been used in each sub-grid. 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.As you gain more experience, you may start to develop your own strategies and techniques for solving the puzzles more quickly and efficiently. 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.īy following these steps, you should be able to solve most Sudoku 4×4 puzzles with ease.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.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. Use the process of elimination: As you fill in more cells, you may start to see patterns and possibilities for other cells.

Move to the next sub-grid: Once you have filled in one sub-grid, move on to the next one, and repeat the process.

Check for duplicates: As you fill in the sub-grid, make sure to check for any duplicates in the rows and columns.

Make sure that each number is used only once in the sub-grid.

Focus on one sub-grid: Pick one of the four sub-grids, and start filling in the numbers 1-4 in the empty cells.

This will help you to identify which numbers are missing and which numbers have already been used.

Start by scanning the puzzle: Look at the puzzle and identify any numbers that are already filled in.
