Note that when I want to talk about the amount of a number, I will use words. When I am talking about an actual number, I will use the number itself. So I will talk about ‘two 1s’ or ‘three 4s’. I will not say ‘2 ones’ or ‘3 3s’.

Now, let’s get started!

What Are Sudoku 4×4 Puzzles?

First of all, let’s look at an empty Kids’ Sudoku 4×4 Puzzles grid. As you can see, it is made up of FIVE boxes. There is a BIG box which has FOUR rows and FOUR columns. Plus, there are also FOUR smaller boxes which have TWO rows and columns i.e. they are 2×2 boxes.

By the way, I have numbered the rows and columns to make things easier to explain. However, when you do Sudoku puzzles for real, there will not be any numbers because you won’t need them.

Before we talk about how to solve a Kids’ Sudoku 4×4 Puzzles, it’s important to understand that to complete the puzzle, each row, column, and 2×2 box must have the numbers 1 to 4.

And the second important thing to remember is that NO number can be repeated. So, 2-4-1-3 is possible in a row, column, or 2×2 box, but 1-4-2-1 is NOT because there are two 1s.

So, how do we actually solve a Sudoku 4×4 puzzle? Let’s do this step-by-step.

Step 1

By far the easiest way to start is also the most obvious. Look for any row, column, or 2×2 box and see if they contain three numbers. If any do, then there can only be one missing number.

For example, if one row contains the numbers 1, 3, and 4, then the only possible number you can write in the remaining square is 2. This is also the case for columns and 2×2 boxes. Let’s look at an example:

Step 2

When you try to do Step 1, you may find that there are only rows, columns, and 2×2 boxes that have two or more numbers missing. If this is the case, then you need to look at ALL the puzzle to help you out. Let’s look at another example:

In the above example, you can see that there are not many numbers, but that doesn’t mean it’s impossible to solve. The bottom right-hand 2×2 box has the numbers 1 and 4. And you can also see that the bottom left 2×2 box has the number 4.

Now, because we know that numbers CANNOT be repeated, we know that a 3 goes in the top corner of the bottom right-hand 2×2 box and a 2 goes into the remaining space. Check out the example below:

Step 3

Now, look at the bottom left-hand 2×2 box in the example above. It only has ONE number but because the bottom right-hand 2×2 box is complete, we can now write in the numbers. Try to do the it now BEFORE you look at the next image.

Did you get it right? Well done if you did. Don’t worry if you didn’t; these puzzles take practise.

Now, let’s look at the top half of the puzzle. You will no doubt see that we now have three columns with only one missing number. Plus, we have Column #4 with two missing numbers but if we do Columns #1 – #3 first, the last column will be easy. Now, you will be able to complete the whole puzzle. Try it yourself before looking below.

So, did you manage to complete the entire puzzle? If you did, well done! You are well on your way to becoming a Sudoku puzzle solving champ! And if you didn’t, it’s not the end of the world. With just a little more practice, you’ll be solving Sudoku puzzles like a champ very soon too!

If you think you know what to do now, you can get Sudoku solving. If you need some more help, then this next section is for you. Let’s look at another Kids’ Sudoku 4×4 Puzzle example:

The example above looks a bit strange and when you first saw it, you probably thought it is quite difficult but as long as you remember the steps, you shouldn’t have too many problems.

Step 1

If you look at Row #1, it contains ‘?, 3, 4, ?’ and if you look at Column #1, you can see it contains ‘?, 4, 1, ?’. So, Row #1 must be either 1, 3, 4, 2 or 2, 3, 4, 1. However, because we know that numbers CANNOT be repeated and Row #1 already as a 1 in it, the answer CANNOT be 1, 3, 4, 2 so Row #1 must be 2, 3, 4, 1.

Now, we have completed Row #1, we can also complete Column #1 and Column #4, which will also complete Row #4. See if you can do it before you look at the solution below.

Step 2

I am sure you have noticed that, in this example, we have managed to complete all the outside numbers. And I am also sure that you have noticed that each 2×2 box has just one number missing, making it very easy to complete the puzzle. The finished puzzle is below but see if you can do it yourself first.

Did you do it? Of course you did because it was easy!

Now we’re going to do one more example but this time we’re going to start with one of the more difficult Kids’ Sudoku 4×4 Puzzles. If you think you know what you’re doing NOW, go and get Sudoku 4×4 puzzle solving! If you don’t, this last section will make everything clear.

In the example below, you can see that we only have FOUR numbers. “What!?” I hear you cry, “No way can I do that!” Relax! It’s not as difficult as it looks. Let’s look at how to solve it together. You can even try to do it yourself first if you want.

Step 1

Remember that the way you do it may be different from the way I do it. It doesn’t matter. The only important thing is to do it and to do it without guessing. All Sudoku puzzles can be worked out logically. If you need to guess, you are missing something so you need to look at the clues more closely.

Step 2

If you look at the top and bottom right-hand 2×2 boxes, you will see that there is only one place you can put the 4 so write it in. Now that we have the 4 and 1 in the top right-hand 2×2 box, we know where the 2 and 3 go. Look at the top left-hand 2×2 box for help. If you’re following me, you should have this:

You should see that both Row #1 and Column #4 only have ONE number missing so you can fill those two answers in. Now go back to the bottom right-hand 2×2 box and fill in the two missing numbers. Look at the bottom left-hand box to help you. You should now have a grid that looks like this:

Step 3

You will notice that Row #3 has only ONE number missing, so you can fill out that number. And finally, you should be able to complete the puzzle with all the clues you now have.

Wrapping It All Up

If you have done everything right, you should have a solution that looks like this:
