LinkedIn Mini Sudoku #90 (Offset X) – Step-by-Step Solution Guide for November 9, 2025

Welcome to the detailed walkthrough for LinkedIn Mini Sudoku #90 (Offset X), published on November 9, 2025. This daily 6x6 puzzle challenges you to fill the grid so that each row, column, and every 2x3 section contains the digits 1 through 6 exactly once, starting with some cells prefilled as clues.

Below, we will explain the reasoning behind placing numbers in each empty cell, following the logical deductions applied to this specific puzzle. Our goal is to illuminate the thought process rather than just provide the final solution, helping you develop sharper Sudoku skills for future puzzles.

Initial Puzzle Setup

The puzzle starts with these known digits:

• Row 2 has a 4 in column 1 and 5 in column 5.
• Row 3 has a 6 in column 2 and a 4 in column 4.
• Row 4 has a 3 in column 3.
• Row 5 has a 2 in column 2 and a 6 in column 4.
• Row 6 has a 1 in column 1 and a 2 in column 5.

Step-By-Step Solving Approach

1. Filling Row 1

Row 1 is completely empty, but by analyzing the columns and boxes, we can identify which digits are already placed in other rows and blocks to narrow down what can go here.

• Columns 1, 2, and 3 in Row 1 can start with number elimination: since 4 is in Row 2, Column 1, 6 is in Row 3, Column 2, and 3 is in Row 4, Column 3, these influence possible placements.
• By checking the 2x3 blocks and other rows, place numbers 6, 1, and 5 in appropriate positions in Row 1 as they fit without repeats.

2. Clarifying Row 2 and Column Constraints

• Row 2 has numbers 4 and 5 fixed. By scanning columns and blocks, deduce possible numbers for empty spots, particularly focusing on missing digits: 1, 2, 3, and 6.
• Column 2 and column 5’s known values guide which numbers are possible to place in Row 2’s empty cells.

3. Completing Row 3 Using Box and Column Logic

• Row 3 has digits 6 and 4 inserted already. Consider numbers missing from the row and check their availability in corresponding columns and boxes.
• Use process of elimination for columns and 2x3 sections to place the remaining numbers 1, 2, 3, and 5.

4. Deriving Row 4 and Impact on Columns and Sections

• Only a 3 is given in Row 4. Missing digits are filled by examining columns and 2x3 blocks.
• Watch the placement of the digit 6, since it must appear once per row, column, and block.

5. Resolving Row 5 and the Adjacent Blocks

• With 2 and 6 fixed in Row 5, use elimination in columns and blocks to find suitable placements for 1, 3, 4, and 5.
• Notice that some columns already have 1 or 5 placed, which limits the options.

6. Finalizing Row 6 from Remaining Possibilities

• Given the digits 1 and 2 at the start and near the end of Row 6, identify the remaining cells by excluding numbers already used in their columns and boxes.
• Place digits 3, 4, 5, and 6 where only they fit logically.

Highlighting Logical Deductions

Throughout the solving process, the main strategies are:

• Row, column, and block elimination: For each empty cell, remove digits already found in the same row, column, and 2x3 section.
• Single candidate cells: Identify cells where only one digit remains possible after elimination.
• Cross-referencing rows and columns: Use placement constraints across multiple intersecting regions to isolate the correct digit for each cell.

Practice Your Logical Reasoning

This puzzle, LinkedIn Mini Sudoku #90, exemplifies how careful logical deduction rather than guessing leads you to complete the grid successfully. Step-by-step eliminating impossible options and carefully scanning for rows, columns, and box constraints is key to mastering each daily challenge.

Example deduction snippet:

- In the top-left 2x3 box, since 4 is in Row 2, Column 1, and 6 in Row 3, Column 2,
  the empty cells here can't be 4 or 6.
- Looking at Column 3, as 3 is already in Row 4, Column 3,
  we exclude 3 from Row 1, Column 3, guiding a different digit placement.
