Hi Gareth, I was wondering whether these type of puzzles are you inventions or not. I tried to google it, and I've found an article where you wrote you invented the odd-pair one, but what about the two others?

Just Odd Pair - Kropki and Consecutive predate me. I think there used to be Kropki puzzles published occasionally before Sudoku, without the box constraints.

I've found those in a hungarian issued puzzle magazine. However the Odd-Pair one had a little different ruleset, marking all the odd and even numbers, not just some neighbouring pairs.
