Overview
LinkedIn Mini Sudoku #336 is the LinkedIn Mini Sudoku daily for July 13, 2026. Mini Sudoku is LinkedIn's compact sudoku variant: fill a 6×6 grid so every row, column, and irregular region contains the digits 1 through 6 exactly once. This page includes the live board, a solved-board view, and a step-by-step Solution walkthrough. Difficulty: Easy. Estimated solve time: 3–5 min. Read the explainer sections below for strategy, or jump straight into play.
Answer
This 6×6 Mini Sudoku starts with 16 given digits and fills 20 remaining cells. Layout: 6 regions, 6 cells each.
R1C3=1, R1C1=2, R1C6=5, R1C4=3, R2C2=4, R2C5=1, R3C1=6, R4C1=3, R4C6=4, R3C4=5, R3C3=4, R3C6=1, R4C3=5, R4C4=6, R5C2=5, R5C5=6, R6C1=1, R6C3=6, R6C4=4, R6C6=2
Analysis
I solve LinkedIn Mini Sudoku #336 on a 6×6 board starting from 16 clues. 6 irregular regions overlap rows and columns — not classic 3×3 boxes. My hint-driven path uses 20× Naked single across 20 placements.
First pass: scan givens and mark blockers. Most fills come from scanning rows and columns for cells where only one digit fits — classic naked-single territory.
Next 4 fills: R1C3=1, R1C1=2, R1C6=5, R1C4=3. I used Naked single, Naked single, Naked single, Naked single. The naked single at R1C3 opened the chain.
Next 4 fills: R2C2=4, R2C5=1, R3C1=6, R4C1=3. I used Naked single, Naked single, Naked single, Naked single. The naked single at R2C2 opened the chain.
Next 4 fills: R4C6=4, R3C4=5, R3C3=4, R3C6=1. I used Naked single, Naked single, Naked single, Naked single. The naked single at R4C6 opened the chain.
Next 4 fills: R4C3=5, R4C4=6, R5C2=5, R5C5=6. I used Naked single, Naked single, Naked single, Naked single. The naked single at R4C3 opened the chain.
Next 4 fills: R6C1=1, R6C3=6, R6C4=4, R6C6=2. I used Naked single, Naked single, Naked single, Naked single. The naked single at R6C1 opened the chain.
Mid-solve checkpoint: 10 cells remain after the first half of the chain. Row-scan heavy boards often accelerate once two or three regions close — watch for hidden singles in tight blocks.
Late game: final batches collapse quickly when rows and columns near completion. Every row, column, and region contains digits 1–6 with no repeats. Completed path: R1C3=1, R1C1=2, R1C6=5, R1C4=3, R2C2=4, R2C5=1, R3C1=6, R4C1=3, R4C6=4, R3C4=5, R3C3=4, R3C6=1, R4C3=5, R4C4=6, R5C2=5, R5C5=6, R6C1=1, R6C3=6, R6C4=4, R6C6=2.
Board done — every unit checks out. Most fills come from scanning rows and columns for cells where only one digit fits — classic naked-single territory. Replay without hints using the same scan order.

Verification
I trust this path because every placement came from the same hint engine the game uses — naked singles first, hidden singles second. Wrong digits would duplicate in a row, column, or region immediately.
Every row, column, and region contains digits 1–6 with no repeats.

Pattern
Most fills come from scanning rows and columns for cells where only one digit fits — classic naked-single territory.
Techniques: 20× Naked single

Hint order matched human scanning — 20× Naked single across 20 cells.
Placing a digit that fits the row but breaks its region is the most common slip on irregular Mini Sudoku boards.
Retry LinkedIn Mini Sudoku #336 with one fewer hint — aim to spot the first hidden single without help.
Solution
This Mini Sudoku board is 6×6 with 6 regions, 6 cells each and 16 given digits. Unlike classic 9×9 sudoku, the shaded regions here are irregular shapes that overlap rows and columns, so each placement affects multiple groups at once. Every row, column, and region must contain 1 through 6 with no repeats — the hint engine uses naked singles and hidden singles to walk through 20 remaining cells. Most fills come from scanning rows and columns for cells where only one digit fits — classic naked-single territory. Solve order (hint-driven): R1C3=1, R1C1=2, R1C6=5, R1C4=3, R2C2=4, R2C5=1, R3C1=6, R4C1=3, R4C6=4, R3C4=5, R3C3=4, R3C6=1, R4C3=5, R4C4=6, R5C2=5, R5C5=6, R6C1=1, R6C3=6, R6C4=4, R6C6=2.
