LinkedIn 6x6 Sudoku #293: Pro-Tips

This grid is a classic speed-run Sudoku: small enough to move fast, but tight enough that one clean deduction unlocks the rest. In a 6x6 layout, the game is about spotting where a row, column, or 2x3 box has only one realistic landing spot left, then letting the constraints cascade.

The first thing to notice

Because LinkedIn Mini Sudoku uses 1 through 6 in every row, column, and box, the strongest early tactic here is cross-hatching. Scan a box, then test each missing number against the row and column it belongs to. On a compact grid like this, that often turns what looks like a vague possibility into a forced placement almost immediately.

The Crucial Square

The puzzle really starts to crack at the center-right area, especially around the box containing the 1 in row 4 and the 4 in row 3. That region is the hinge point: once you narrow the candidates there, the surrounding rows stop being flexible and begin to lock in. In speed-run terms, this is the square set where the puzzle stops feeling like a search and starts feeling like a chain reaction.

The key move is not to chase every open cell. Instead, isolate the box with the fewest open options and ask: which digit is already blocked from every other slot in that box? That is where the first hidden single usually appears.

How the breakthrough happens

After the center-right box tightens, the next payoff comes from the long rows with only two or three blanks. Row pressure matters a lot in 6x6 Sudoku because a partially filled row can often rule out a candidate across multiple boxes at once. When one row and one column agree, the number is no longer a possibility, it is a placement.

That is the moment to switch from scanning to confirming. If a digit can only fit one square in a box, it becomes a hidden single. If a row has a number that can only go in one column, that is the same idea from a different angle. In this puzzle, those two techniques feed each other until the board opens up.

Practical speed-run approach

• Start with the boxes that already contain two givens, because they usually yield the fastest candidate cuts.
• Use cross-hatching to eliminate impossible spots before you try to guess anything.
• Check rows with paired givens early, since they often create a forced missing-digit pattern.
• Watch for a box where a digit is blocked in five out of six cells. That is the kind of setup that produces the first clean hidden single.
• Once one placement lands in the middle of the grid, re-scan the intersecting row and column immediately. The next move is often already exposed.

Where the solve gets easy

Once the central structure is fixed, the outer rows fall in a much more mechanical way. The top row and bottom row both become straightforward because their remaining digits are constrained by the box completions beneath and above them. At that point, the puzzle is no longer about finding new ideas, just executing the remaining forced fills cleanly.

If you are playing for time, the big lesson from #293 is simple: do not overwork the whole grid. Find the box that is most boxed-in, make the first forced move, and let the intersections do the rest.
