Sudoku is a type of number game. You use logic and problem solving, not math, to solve it! Fill in the grid so that every row, every column and every 2×2 box contains the numbers 1, 2, 3 and 4, with no repeats. Each Sudoku puzzle has just one solution.

Puzzle #1

Let’s do the first puzzle together!

Look at the question mark. It can’t be a 3 because there is a 3 in the same row. It can’t be a 4 because a 4 is in the same column. It can’t be a 1 because a 1 is in the same box. What number is it? Fill in the square.

Now move up one square. What number is it? Remember, it can’t be a number that is already used in the same row, column or box.

Move to the left two squares. Looking at the other numbers in the same column and row, there is only one number that can go here.

Now you can look for rows, columns or boxes that already have three numbers filled in and fill the last square. Solve the puzzle.

Puzzle #2

Now you are ready to do the next puzzle by yourself. Need a hint? Start with the question mark.
