Overview
LinkedIn Queens #817 is the LinkedIn Queens daily for July 26, 2026. Queens is LinkedIn's logic puzzle: place exactly one queen in every row, column, and colored region on a 9×9 board, with no two queens touching—even diagonally. This page includes the live board, a solved-board view, and a step-by-step Solution walkthrough. Difficulty: Hard. Estimated solve time: 6–10 min.
Answer
Final queen coordinates for this board:
R1C3, R2C5, R3C1, R4C6, R5C8, R6C2, R7C7, R8C9, R9C4
Several color regions span only a few cells — scan those regions first because they often force a queen into a single row or column.
Analysis
Case LinkedIn Queens #817: 9×9 grid, 9 colored regions. Nine exhibits — queen coordinates R1C3, R2C5, R3C1, R4C6, R5C8, R6C2, R7C7, R8C9, R9C4. No two queens may share row, column, region, or adjacency.
Board spotlight: Several color regions span only a few cells — scan those regions first because they often force a queen into a single row or column. Region sizes range from 1 to 21 cells — smaller regions often pin a queen to a single row intersection.
Exhibit 1: queen at R1C3. Row 1, column 3 is the forced queen once region 2, row, column, and touch rules are applied together.
Exhibit 2: queen at R2C5. Row 2, column 5 is the forced queen once region 4, row, column, and touch rules are applied together.
Exhibit 3: queen at R3C1. Row 3, column 1 is the forced queen once region 1, row, column, and touch rules are applied together.
Exhibit 4: queen at R4C6. Row 4, column 6 is the forced queen once region 6, row, column, and touch rules are applied together.
Exhibit 5: queen at R5C8. Row 5, column 8 is the forced queen once region 5, row, column, and touch rules are applied together.
Exhibit 6: queen at R6C2. Column 2 is the only column still available for a queen in row 6.
Exhibit 7: queen at R7C7. Region 8 only touches row 7 once on this board, so its queen must land at column 7.
Exhibit 8: queen at R8C9. Region 7 only touches row 8 once on this board, so its queen must land at column 9.
Exhibit 9: queen at R9C4. After eliminations, row 9 has one legal square left — column 4.
Verdict: placement set R1C3, R2C5, R3C1, R4C6, R5C8, R6C2, R7C7, R8C9, R9C4 is consistent with every rule. Case closed.
Rows
Placement insight
Row 1, column 3 is the forced queen once region 2, row, column, and touch rules are applied together.
Solving note
Placing here claims row 1, column 3, and region 2. Auto X marks will block 80 other cells from holding another queen in those units. Watch for elimination patterns on similar boards.

Verification
Evidence chain supports R1C3, R2C5, R3C1, R4C6, R5C8, R6C2, R7C7, R8C9, R9C4. Alternative columns in any row would violate region coverage or adjacency.
Takeaways
Coordinates R1C3, R2C5, R3C1, R4C6, R5C8, R6C2, R7C7, R8C9, R9C4 — no row permits an alternate column once prior queens are fixed.
Any cell sharing row, column, region, or diagonal with a placed queen is eliminated — that is most of the grid after step three.
Several color regions span only a few cells — scan those regions first because they often force a queen into a single row or column.
