Step-by-Step Solution to LinkedIn Mini Sudoku #88 (Hexagon) - November 7, 2025

Welcome to the detailed walkthrough for LinkedIn Mini Sudoku #88 (Hexagon), published on November 7, 2025. This 6x6 Sudoku variant requires each row, column, and 2x3 box to contain digits 1 through 6 exactly once. We'll focus on how to logically deduce every empty cell from the initial clues without guessing.

The puzzle starts with a few prefilled numbers, providing key footholds:

• Row 2 has 1, 2, and 3 given.
• Row 3's last cell is 4.
• Row 4 starts with 3.
• Row 5 contains 6 and 4.
• Row 6 has 2 near the middle/end.

Let's break down the solving process step-by-step, focusing on the interplay between rows, columns, and the 2x3 boxes:

Step 1: Fill Obvious Missing Numbers Using Rows

Look at Row 2, which already contains 1, 2, and 3. Missing digits are 4, 5, and 6. By scanning their columns and boxes, we eliminate some options for these numbers. For example, the placement of 6 in Row 5 helps locate where 6 goes in Row 2, narrowing down possibilities further.

Step 2: Examine Columns With Most Clues

Focus on columns with multiple clues. Column 1 has known numbers 1 (Row 2) and 3 (Row 4). Since the digits 1 to 6 must appear uniquely per column, see which digits are missing here and find potential placements by eliminating based on existing row and box constraints.

Step 3: Analyze Each 2x3 Box Independently

Each 2x3 box must contain the digits 1 through 6 once. For example, the box covering Rows 1-2, Columns 1-3 has clues 1 and 2. Missing digits 3, 4, 5, and 6 can be placed logically by checking their presence in intersecting rows and columns. This step helps identify exact cells for tough-to-place numbers.

Step 4: Use Process of Elimination for Single Cells

After filling in some numbers, revisit empty cells and assess which digits remain possible based on their row, column, and box. For instance, if a cell’s row, column, and box collectively contain digits except one, that digit goes into that cell.

Step 5: Systematic Sequential Filling

Applying the above logic repeatedly enables filling each blank spot. For example, the cell in Row 1, Column 6, initially empty, can only be a '1' because all other digits appear in its row, column, or box. Similarly, Row 6’s first cell can only be '4' due to the same constraints.

Additional Tips While Solving

• Keep cross-checking rows and columns whenever you place a number.
• Filling easier cells first creates clues that simplify harder placements.
• If stuck on a particular number, shift focus to others and return later with fresh information.

Using this step-by-step logic, the entire grid gradually completes with all digits 1 to 6 filling each row, column, and 2x3 box without repetition. This approach ensures a purely logical solution path, characteristic of the LinkedIn Mini Sudoku challenge.
