LinkedIn Mini Sudoku #110 (Fenced In) - Step-by-Step Solution Guide

Welcome to the detailed walkthrough of LinkedIn Mini Sudoku #110, also known as Fenced In, published on November 29, 2025. In this 6x6 Sudoku variant, each row, column, and 2x3 section must contain the digits 1 through 6 exactly once. Let’s explore how to logically solve this puzzle starting from the given clues.

The puzzle grid comes partially filled, giving us anchor points to begin deduction. Here’s how we proceed step-by-step:

1. Analyze Pre-Filled Cells and Identify Constraints

The initial clues include placements such as a 6 in the first row’s fourth cell, and several other numbers scattered across rows and 2x3 blocks. These serve as fixed points to eliminate possibilities elsewhere.

2. Focus on Rows and Columns Close to Completion

For example, examining the fourth row where 3 and 2 are already placed in the first two cells, we scan for missing numbers. With 3 and 2 occupying these positions and 4, 6, 5 missing, the empty cells in this row become candidates for the remaining digits, refined by checking overlapping columns and boxes.

3. Use Box-Based Deduction

Each 2x3 box must contain digits 1 through 6 exactly once. Scanning a box, such as the bottom-right 2x3 block, we see some digits placed — 3, 2 in certain cells — which immediately limits what can be placed in the remaining empty cells of that box.

4. Employ Scan and Eliminate Techniques

Take the number 1 as an example. It appears in some rows and columns already, so we mark its absence in others. For each empty cell, we consider the numbers already present in its row, column, and box, eliminating those candidates from the cell’s possibilities.

5. Fill Easy, Forced Cells

Once elimination narrows down a cell to a single eligible number, that cell gets filled, which then cascades—updating possibilities for other cells in the same row, column, and box.

6. Repeat Logical Sweeps Across the Grid

By alternating focus between rows, columns, and 2x3 blocks, we iteratively identify numbers for cells from most constrained to least. For instance, after completing certain numbers in the top two rows, returning to the middle or bottom sections benefits from the new placements.

7. Verifying Against Puzzle Rules

With each addition, ensure no row, column, or 2x3 box contains duplicates. This vigilance keeps the solution valid throughout the process.

Example Highlight: Determining a Specific Cell

Consider the empty cell in the first row, first column. The numbers already in the first row are 6 and others identified through deduction. The column already contains some digits, and the box limits others. By excluding these from 1–6, the remaining candidate can be confidently placed.

Step: Cell at Row 1, Column 1
- Row 1 has digits: 6 (known), plus others found through solving
- Column 1 has digits: 3 and 2 (from Row 4 and Row 5)
- Box (top-left 2x3) also restricts possible numbers
=> Remaining digit for this cell is 4

Repeat such logical deductions throughout the grid to fill all empty cells systematically.

By carefully applying these strategies, you progress steadily from the initial clues to the fully solved puzzle grid without guesswork. This systematic reasoning encapsulates the satisfying challenge of LinkedIn Mini Sudoku puzzles like Fenced In.
