What are Parson’s puzzles?
Parson’s puzzles are designed to get you thinking about the order of code, and think logically about how code can be constructed.
In a Parson’s puzzle you have all the code that you need – you just need to put it into the right order!
In terms of computational thinking, the puzzle is asking you to think about the design of the algorithm, without having to worry about the actual code you need or that you have got the syntax correct.
What is the difference between normal and Challenge tasks?
In normal tasks you are not expected to use indentation as the indentation has already been done for you. In challenge tasks you are expected to drag blocks to a correctly indented place in order to complete the puzzle correctly.
