How to Solve LinkedIn Mini Sudoku #164: Ode to 22

Game: LinkedIn Mini Sudoku | Puzzle ID: 164 | Puzzle Name: Ode to 22 | Published: January 22, 2026

This 6x6 Sudoku puzzle challenges you to fill empty cells so that each row, column, and 2x3 box contains all digits from 1 to 6 exactly once. Let's break down the solving strategy step-by-step using logic and elimination techniques.

Understanding the Starting Position

Our puzzle begins with these clues:

6 5 . . . .
. 4 . . . .
3 . . . 5 2
2 1 . . . 6
. . . . 4 .
. . . . 2 5

With only 12 clues provided, you'll need to apply systematic elimination and pattern recognition to uncover all 36 numbers.

Step-by-Step Solution Strategy

Start with Rows and Columns with Most Clues

Begin by examining units (rows, columns, and 2x3 boxes) that already contain the most pre-filled numbers. These sections offer the easiest solving opportunities.

Row 3 Analysis: This row has four numbers already (3, 5, 2, and needs 1, 4, 6). By checking what's missing in each 2x3 box and column, you can narrow down possibilities quickly.

Row 4 Analysis: With 2, 1, and 6 placed, only 3, 4, and 5 remain. Use column constraints to determine exact positions.

Use the Process of Elimination

For each empty cell, identify which numbers are already present in:

• The cell's row
• The cell's column
• The cell's 2x3 box

Eliminate these numbers from your candidates. The remaining possibilities narrow down significantly.

Identify Naked Singles

A naked single occurs when only one number can logically fit in a cell. These are your quickest wins:

• Row 1, Column 3: Check what's missing in the top-left 2x3 box and Row 1. This cell becomes determinable through box and row constraints.
• Row 2, Column 1: The leftmost column and top-left box contain specific numbers already. Eliminate candidates systematically.

Work Through Column Constraints

Column 1 contains 6, 3, and 2. Missing: 1, 4, 5. By checking which rows can accommodate each number in their respective boxes, you'll place all three.

Column 2 has 5, 4, and 1. Missing: 2, 3, 6. Examine the 2x3 boxes to determine exact positions for remaining numbers.

Focus on One Number at a Time

Concentrate on placing all instances of a single digit throughout the puzzle. For example, if 5 appears twice, only four more positions remain. This focused approach often reveals multiple cells simultaneously.

Placing All 3s: Identify where 3 can go in each row, column, and box. Working through the grid methodically, you'll find each position for the digit 3.

Apply Box/Line Reduction

When a number in a 2x3 box can only appear in one row or column within that box, eliminate it from other cells in that row or column outside the box. This advanced technique accelerates solving.

Use Pencil Marks for Complex Areas

For cells with multiple candidate possibilities, write down all potential numbers. As you place confirmed digits elsewhere, erase impossible candidates. This creates a visual map of logical deductions.

Solving the Harder Sections

The middle rows and columns typically contain fewer initial clues, requiring more deductive reasoning:

• Work from already-solved adjacent cells and boxes
• Check row sums and column requirements continuously
• Look for pairs or groups of cells that constrain each other

Verification Strategy

As you complete each row, column, and 2x3 box, verify that all digits 1-6 appear exactly once. This prevents cascading errors and confirms your logic is sound.

Key Takeaway

LinkedIn Mini Sudoku #164 rewards systematic elimination over guessing. By combining naked singles, box/line reduction, and focused candidate analysis, you'll solve this puzzle efficiently. Start with high-clue areas, work through each constraint type methodically, and watch the solution emerge logically.
