What made Sudoku so special compared to other puzzles?...

I was thinking the other day, as you do, about puzzles!

And I was trying to work out what it was that made sudoku so different to other puzzles.

New puzzle ideas come and go all the time, but apart from a couple of word puzzles such as wordsearch and crossword, no puzzle has ever had massive success and consistent success that I can think of.

And certainly not a logic puzzle!

So what was it about sudoku that made it SO good that everyone had to have it and every newspaper was desperate to get it?

Because I like the puzzle but I don't find it better than many other logic puzzles, in fact there are many other logic puzzles that I personally prefer.

So does it largely come down to marketing or is there some particular quality that sudoku has that other logic puzzles do not have???
