I have uploaded a new Version 8.4 of REAKTOR RIDDLES. I have added a solution for riddle 8.3. I am not sure whether i had planned to show other solutions in November 2016. Have to read my own document after two months. Perhaps i will add the others later and update the document. For now i have added only a new riddle (8.4). It is the last riddle for use of partials framework for now. Chapter 9 will be about arrays in core (finally). So let me add some comments and questions to 8.4 in next post here.
