LinkedIn Mini Sudoku #101 (2x🌈Rainbow) Solution – November 20, 2025

Welcome to the daily solution for LinkedIn Mini Sudoku #101 (2x🌈Rainbow), published on November 20, 2025. This 6x6 Sudoku puzzle challenges your logic with a colorful twist, but the rules remain simple: every row, column, and 2x3 box must contain the digits 1 through 6 exactly once. Let’s walk through each step to solve this puzzle.

Starting the Puzzle

Here’s the initial grid:

  .   .   3   4   .   .
  .   2   .   .   5   .
  1   .   .   .   .   6
  .   .   5   3   .   .
  .   6   .   .   1   .
  2   .   .   .   .   4

Step 1: Fill Obvious Singles

Look for rows, columns, or boxes with only one missing number. In the third row, we have 1 and 6, so the missing numbers are 2, 3, 4, and 5. But the third column already has 3 and 5, so 2 and 4 are the only options for the empty cells in that row. However, the second column already has a 2, so the cell at row 3, column 2 must be 4. Now, row 3 looks like:

  1   4   .   .   .   6

Step 2: Use Column and Box Constraints

Now, look at the first column. We have 1 and 2, so the missing numbers are 3, 4, 5, and 6. The first box (top-left 2x3) already has 3 and 4, so the remaining cells in that box must be 5 and 6. The cell at row 1, column 1 can’t be 5 because row 1 already has a 5 in column 5, so it must be 6. The cell at row 2, column 1 must then be 5.

Step 3: Progress Through the Grid

Continue this process, checking each row, column, and box for missing numbers and using the process of elimination. For example, in the second row, we now have 5 and 2, so the missing numbers are 1, 3, 4, and 6. The second box (top-right 2x3) already has 4 and 5, so the remaining cells must be 1, 3, and 6. The cell at row 2, column 3 can’t be 1 because column 3 already has a 1, so it must be 3 or 6. But row 2 already has a 3 in column 1, so it must be 6. Continue this logic for each cell.

Step 4: Complete the Puzzle

As you fill in more numbers, the puzzle becomes easier to solve. Use pencil marks to keep track of possible numbers for each cell, and eliminate options as you go. Focus on one number at a time, and use the process of elimination to narrow down possibilities. Eventually, you’ll fill in all the cells and complete the puzzle.

Remember, the key to solving Sudoku is patience and logic. Take your time, and don’t be afraid to use pencil marks to help you keep track of possibilities. With practice, you’ll become a Sudoku master!
