Sudoku 6x6 is a variant of the classic Sudoku puzzle, tailored to be more accessible and often used as an introductory version of the puzzle. It features a 6x6 grid, which is divided into smaller 2x3 regions. Some cells within the grid are pre-filled with numbers, serving as clues to aid in solving.

- Pre-filled Numbers: Some cells are pre-filled with numbers 1 through 6, serving as clues.
- Objective: The goal is to fill the empty cells in such a way that each row, column, and region contains the numbers 1 through 6 without any repetition.
- No Repetition: A number cannot appear more than once in a single row, column, or 2x3 region.

Basic Solving Tips
- Single Possibility: If a cell has only one possible number that can be placed in it, fill it in.
- Exclusion: Identify numbers that cannot be in a particular cell, to narrow down the possibilities.
- Row and Column Checking: Ensure that each number appears once and only once in each row and column.
- Region Checking: Similarly, ensure each number appears once in each 2x3 region.
- Pencil Marks: Use pencil marks to note down possible numbers for a cell, and update them as you progress.
