Sudoku 6x6 rule
The puzzle is played on a 6x6 grid, instead of a 9x9 grid.
There are 6 numbers to choose from (1, 2, 3, 4, 5, and 6).
Each row, column, and 3x3 block must contain each of the numbers 1, 2, 3, 4, 5, and 6 exactly once.
As you can see, the puzzle has 6 rows, 6 columns, and 3x3 blocks. The numbers 1, 2, 3, 4, 5, and 6 must appear exactly once in each row, column, and 3x3 block.
6x6 Sudoku is a simpler puzzle than regular Sudoku, but it can still be challenging. If you are a beginner to Sudoku, I recommend starting with 6x6 Sudoku puzzles. Once you have mastered 6x6 Sudoku, you can then try regular Sudoku puzzles.
Here are some tips for solving 6x6 Sudoku puzzles:
Start by looking for clues in the existing numbers. For example, if a number appears only once in a row, then it must be the missing number in that row.
Look for patterns in the numbers. For example, if a number appears in two of the three rows in a 3x3 block, then it must also appear in the third row.
Use elimination to rule out impossible numbers. For example, if a number appears in a row and a column, then it cannot also appear in the corresponding 3x3 block.
Be patient and persistent. 6x6 Sudoku puzzles can be challenging, but they are also very satisfying to solve.
