LinkedIn Mini Sudoku #112 (Packed Ls) - December 1, 2025: Step-by-Step 6x6 Puzzle Walkthrough

Welcome to the detailed solution guide for LinkedIn Mini Sudoku #112 (Packed Ls), published on December 1, 2025. In this unique 6x6 sudoku challenge, each row, column, and 2x3 box must contain the digits 1 to 6 exactly once. Let's explore the logical steps to fill every empty cell based on the clues and constraints.

The puzzle begins with several given numbers scattered across the grid, providing key anchors. Our goal is to methodically fill each cell by applying classic Sudoku logic adapted to the 6x6 size and the 2x3 sections.

Step 1: Analyze Rows and Columns with Most Clues

Start by examining rows and columns that already have multiple numbers filled, which narrows down missing digits quickly. For instance, the bottom row already contains four digits: 4, 5, 6, and 1. This leaves only digits 2 and 3 to place, and by checking which digits are present in the respective columns and box, we determine their exact positions.

Step 2: Use Box Constraints for Further Deduction

Consider each 2x3 box as its own small set where digits 1 through 6 must be unique. For example, one box might already have the numbers 2, 5, and 6 placed. The remaining three cells in this box must then be 1, 3, and 4 but locations depend on the numbers already placed in the overlapping rows and columns.

Step 3: Identify Singles by Elimination

Next, look for naked singles, where a cell has only one possible number that can fit due to other numbers already placed in its row, column, and box. Such cells are direct placements without guessing. For example, a cell in a partially filled box and row might be the only place where digit 3 can go because other cells are blocked by the same digit elsewhere.

Step 4: Apply Cross-Hatching Technique

Cross-hatching involves scanning rows and columns within each box to eliminate impossible cells for a particular digit. If a digit cannot appear in all but one cell of a box, that cell is confirmed. These deductions unlock multiple cells progressively.

Step 5: Sequentially Filling Remaining Cells

Continue this logical elimination through each row, column, and box, filling cells one by one as possibilities reduce. When one number is placed, it affects the options for other cells through exclusion, simplifying the puzzle step-by-step.

Additional Tips for This 6x6 Puzzle

• Track candidates mentally or with pencil marks to keep note of which digits might fit where.
• Focus on rows or boxes with the highest number of clues first to gain traction.
• Stay consistent applying the uniqueness rule for each row, column, and box to ensure no duplicates.

By following these systematic strategies based on provided clues, you will steadily unlock the solution, filling all empty cells correctly. This puzzle is a fine example of how logical reasoning unveils the complete grid without guessing.
