LinkedIn Mini Sudoku #114 (HI 👋) - Step-by-Step Solution Guide for December 3, 2025

Welcome to the detailed solution walkthrough for LinkedIn Mini Sudoku #114 (HI 👋), published on December 3, 2025. This 6x6 Sudoku variant requires filling each row, column, and 2x3 block with digits 1 through 6 exactly once. Starting with given clues, we'll logically deduce each empty cell's value.

The puzzle is identified by question_id 114.

Initial Clues Recap:
We begin with the following clues on the board:

• Row 1: 3 in first cell, 5 in third cell.
• Row 2: 2, 1, 4 in columns 1 through 3 respectively.
• Row 3: 1 in first cell, 3 in third cell.
• Row 4: 1, 2, 3 in the last three cells (columns 4–6).
• Row 5: 4 in fifth cell.
• Row 6: 2, 5, 6 in last three cells.

Our goal is to fill the remaining empty cells by applying classic Sudoku logic, focusing on the constraints of rows, columns, and the 2x3 blocks. The 6x6 grid is divided into six blocks, each covering two rows and three columns.

Step 1: Analyze the First Box (Rows 1–2, Columns 1–3)

Known digits: Row 1 has 3 and 5; Row 2 has 2, 1, and 4.

• Check Row 1 missing numbers: 1, 2, 4, 6. Since Row 2's first three columns already include 1, 2 and 4, the only missing number in the first box for Row 1 is 6.
• Place 6 at Row 1, Column 2.
• Row 1, Columns 4–6 are empty; proceed stepwise.

Step 2: Fill Row 1 Remaining Cells

• Row 1, Columns 4–6 must contain digits 1, 2, 4 because other digits are already present in the first half of the row.
• Check numbers already existing in columns 4–6 and blocks 2 and 3.
• For Column 4, digits 1, 2, and 5 need placement; since 5 is in Row 3, Column 5, we can try to place 1 and 2 logically.

Step 3: Focus on Fourth Box (Rows 3–4, Columns 4–6)

• Row 4 has 1, 2, 3 in columns 4 to 6 respectively.
• The block must have digits 1 through 6 without repetition.
• Given Row 3, columns 4–6 empty, digit 5 and 6 should fit here as they are missing.
• Based on columns and rows, place 5 and 6 accordingly using elimination.

Step 4: Complete Third Box (Rows 3–4, Columns 1–3)

• Row 3 has 1 and 3 given; missing numbers 2, 4, 5, 6.
• Row 4 missing numbers in first three columns are 4, 5, 6.
• Check overlapping column and row constraints to place missing numbers logically.

Step 5: Fill Fifth and Sixth Boxes (Rows 5–6, Columns 1–6)

• Row 5 has 4 in column 5; the remaining cells must contain 1, 2, 3, 5, 6.
• Row 6 has 2, 5, 6 in columns 4–6; missing digits 1, 3, 4 need placement in the first three cells.
• Use column and box constraints to fill in these cells by elimination and ensuring no duplication.

Step 6: Cross-Check Columns for Missing Digits

• Examine each column to determine which digits remain and identify cells with single possibilities (naked singles).
• Apply elimination logic referencing filled rows and blocks to narrow down candidates.

Step 7: Iterative Refinement

Repeatedly loop back over rows, columns, and blocks, filling in deduced digits and narrowing possibilities until every cell is filled without conflicts.

Tips for Solving This 6x6 Sudoku

• Focus first on boxes or rows/columns with the most prefilled numbers for easier deductions.
• Use elimination techniques to rule out numbers in cells based on existing digits in the same row, column, and box.
• Identify naked singles, where a cell has only one possible digit left, to place numbers confidently.
• Keep track of possible candidates in ambiguous cells to visualize options and eliminate them as you progress.
