LinkedIn Mini Sudoku #94 (Unlucky #?) Solution Walkthrough – November 13, 2025

Welcome to the detailed solving guide for LinkedIn Mini Sudoku #94 (Unlucky #?), published on November 13, 2025. In this 6x6 number puzzle, the challenge is to fill every row, column, and 2x3 section with numbers from 1 to 6, with no repeats. We'll focus on the specific puzzle marked by question_id 94 to explain the logic and deduction steps used to reach the solution from the initial clues.

Initial Setup: The puzzle starts partially filled with some key numbers. The goal is to analyze constraints imposed by these clues and progressively fill in the blanks, ensuring consistency across rows, columns, and blocks.

Step 1: Analyze Rows and Boxes with Most Clues

Start by identifying rows, columns, or 2x3 boxes nearly complete to reduce possibilities:

• Row 2 contains four numbers: 1, 3, 4, 2. The missing numbers are 5 and 6. Checking other constraints in the corresponding columns and the box can determine their exact positions.
• Row 5 has five numbers: 3, 1, 2, 5 with only one empty cell. The missing number must be 4, as it's the only number not present in the row or box.

Step 2: Use Column Analysis to Narrow down Possibilities

Each column must also have numbers 1 to 6 without repetition. For example:

• Look at Column 1 which already has numbers 1, 3, and 5.
• The missing numbers are 2, 4, and 6. Consider the rows and boxes intersecting with these empty cells to deduce which of these numbers can fit.

Step 3: Filling Boxes and Applying Box-Row-Column Constraints

The grid is divided into six 2x3 blocks. The missing numbers in each block must be carefully placed by cross-checking numbers already used in those blocks' rows and columns.

• For instance, in the top-left 2x3 block, empty cells must be filled with numbers missing from the block while respecting row and column restrictions.
• This logical cross-referencing significantly reduces options for each empty cell.

Step 4: Focus on One Cell at a Time

When stuck, pick an empty cell and list out possible candidates based on already used numbers in its row, column, and box:

Cell (1,1) possibilities exclude numbers already in row 1 (2), column 1 (1,3), and the box.

After elimination, only one number should fit.

Step 5: Progressively Fill the Grid

By repeating the previous steps—checking rows, columns, and boxes—the puzzle unfolds logically:

• The process of elimination leads to certain cells being definitively assigned numbers.
• This, in turn, opens up further placements as the constraints tighten with each step.

Key Logical Highlights

• Utilizing rows and columns with 4 or 5 clues first streamlines deduction.
• Maintaining awareness of each 2x3 block’s missing numbers is crucial to avoid conflicts.
• Checking potential candidates for each empty cell prevents trial and error and promotes logical reasoning.

This approach exemplifies structured problem-solving in Mini Sudoku puzzles, gradually transforming the incomplete grid into a fully valid solution.
