🔍 Understanding 6x6 Sudoku Rules

In a 6x6 Sudoku, the grid is divided into six 2x3 boxes (also called regions). The goal is to fill in each cell so that:
- Each row contains the digits 1 through 6, with no repeats.
- Each column contains the digits 1 through 6, with no repeats.
- Each 2x3 box contains the digits 1 through 6, with no repeats.

#### ✔ Check 2x3 Boxes

There are 6 boxes:

1. Top-left (rows 1–2, cols 1–3):
- 5,6,2
- 4,3,1 → Contains 1–6 → ✔

2. Top-right (cols 4–6):
- 1,4,3
- 2,5,6 → ✔

3. Middle-left (rows 3–4, cols 1–3):

💡 How to Solve It Yourself (Strategy Tips)

If you were solving this without the answer, here’s how:

1. Look for missing numbers in rows/columns/boxes.
2. Use process of elimination — if a number can only go in one cell in a row, place it there.
3. Focus on filled areas — cells near many clues are easier to deduce.
4. Check intersections — use constraints from both row and column.

For example:
- In the first row: 5, _, _, 4, 3 → missing 1,2,6.
- Column 2 has: 6,3,4,1,5,2 → missing 6? Wait, no — let's check again.

Wait — actually, in the solution, the first column is:
- 5, 4, 6, 2, 3, 1 → all present.

But in the puzzle, only some are given.

Let’s try filling in one cell manually.

Take cell (1,2) — row 1, column 2.

Row 1: 5, ?, ?, 4, 3 → missing 1,2,6
Column 2: ?, 1, 3, ?, 4, 2 → values: ?,1,3,?,4,2 → missing 5,6
Box (top-left): contains 5,4,?,? → need 1,2,3,6

So possible values for (1,2): must be in {1,2,6} ∩ {5,6} = {6}

So (1,2) = 6 → matches the solution.

This is how logic works!
