CTC puzzle by Prasanna Seshadri

We're thrilled to be able to share this special sudoku designed by Prasanna Seshadri with you. This puzzle is very unusual in that it involves 14 different sudoku variants!!
The sheer length of the ruleset makes it difficult to include them all on the right-hand side on the video screen SO we're going to publish the puzzle here and then, in a few days time, our video solve will appear on the main channel.
Prasanna is one of the world's best setters/solvers so enjoy!
