Have you tried sudokus before?

Well done for all your hard work this week! 

Today, we are going to solve some sudokus! Have you heard of them before? 

Sudokus are one of the most popular puzzles in the world. You can easily find them in the newspaper. You need to be logical, patient and tenacious to solve them!

There are many types of sudokus. Today, we are going to focus on the 6 X 6 ones. 

Here is an example:

Rule #1: 

- Each row and column must contain all digits from 1 to 6. 

- You cannot use the same digit more than once in each row or column. 

For example, the blue 1 is wrong because 1 is already used in the same column (highlighted 1)
1 CANNOT be in that box. It should be a 5 instead. 

Rule  #2: 

- Each rectangle should contain all digits from 1 to 6 and they cannot repeat as well! 

- See the rectangles in different colours. Same for those on the right.

If you think these are too hard, you can have a go at this 4 X 4 one. Same rules apply but the numbers only go up to 4.
