LinkedIn Mini Sudoku #307 Answer & Analysis

Row 1 already contains 4, 3, 2, and 1, so the missing digits are 5 and 6. Column 5 is the better fit for 5, which makes R1C5 = 5 and leaves R1C6 = 6. That immediately helps the top-right box, where the remaining values in Row 2 must become 3 and 4. Column 6 then forces R2C6 = 4, R2C4 = 3, and Column 3 finishes the row with R2C3 = 6.

Column 5 now reads 5, 2, blank, blank, 6, blank, so the missing digits are 1, 3, and 4. In Row 3, the only place for 1 is R3C5, so R3C5 = 1. That reduces the box at R3-R4 and C4-C6 to the set {2,4,6}. From there, the box forces R3C4 = 6, R4C5 = 4, and R4C6 = 2.

Row 4 now looks like 6, blank, blank, 5, 4, 2, so it still needs 1 and 3. Column 2 can only take 1 in R4C2, which leaves R4C3 = 3. With Row 4 solved, the box covering R3-R4 and C1-C3 becomes easy: R3C1 = 5 and R3C2 = 2. That completes Row 3.

Column 4 now has 1, 3, 6, 5, blank, blank, so only 2 and 4 remain. That gives R5C4 = 2 and R6C4 = 4. Then Column 1 and the bottom-left box force R5C1 = 3 and R6C1 = 2. Column 2 gives R5C3 = 1 and R6C2 = 6. Row 5 is then left with R5C6 = 5, and Row 6 finishes with R6C6 = 1. This confirms the final today's Mini Sudoku solution and satisfies every row, column, and 2x3 box rule.

The completed 6x6 Mini Sudoku solution is: Row 1: 4 3 2 1 5 6; Row 2: 1 5 6 3 2 4; Row 3: 5 2 4 6 1 3; Row 4: 6 1 3 5 4 2; Row 5: 3 4 1 2 6 5; Row 6: 2 6 5 4 3 1.
