Overview
LinkedIn Queens #789 is the LinkedIn Queens daily for June 28, 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:
R1C5, R2C1, R3C7, R4C3, R5C9, R6C2, R7C8, R8C4, R9C6
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
Board classification LinkedIn Queens #789. Dimensions 9×9. Region sample count 9. Observed pattern: tight-region board. Placement vector: R1C5, R2C1, R3C7, R4C3, R5C9, R6C2, R7C8, R8C4, R9C6.
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 2 to 25 cells — smaller regions often pin a queen to a single row intersection.
Sample placement 1: R1C5. Constraint class: elimination. Row 1, column 5 is the forced queen once region 1, row, column, and touch rules are applied together.
Sample placement 2: R2C1. Constraint class: elimination. Row 2, column 1 is the forced queen once region 4, row, column, and touch rules are applied together.
Sample placement 3: R3C7. Constraint class: elimination. Row 3, column 7 is the forced queen once region 2, row, column, and touch rules are applied together.
Sample placement 4: R4C3. Constraint class: regionPin. Region 5 only touches row 4 once on this board, so its queen must land at column 3.
Sample placement 5: R5C9. Constraint class: elimination. Row 5, column 9 is the forced queen once region 3, row, column, and touch rules are applied together.
Sample placement 6: R6C2. Constraint class: elimination. Row 6, column 2 is the forced queen once region 6, row, column, and touch rules are applied together.
Sample placement 7: R7C8. Constraint class: elimination. Row 7, column 8 is the forced queen once region 7, row, column, and touch rules are applied together.
Sample placement 8: R8C4. Constraint class: elimination. Row 8, column 4 is the forced queen once region 8, row, column, and touch rules are applied together.
Sample placement 9: R9C6. Constraint class: rowScan. After eliminations, row 9 has one legal square left — column 6.
Lab result: Tight-region board. Coordinates R1C5, R2C1, R3C7, R4C3, R5C9, R6C2, R7C8, R8C4, R9C6.
Rows
Placement insight
Row 1, column 5 is the forced queen once region 1, row, column, and touch rules are applied together.
Solving note
Placing here claims row 1, column 5, and region 1. Auto X marks will block 80 other cells from holding another queen in those units. Watch for elimination patterns on similar boards.
