Maybe there is a missing period before the word 'only'.
This puzzle is cool and friendly enough to solve **entirely by imagination** :D

Very confusing, it took me a while to see why this sudoku has only 1 solution. If that fact was clearer it would be an amazing new type of sudoku. Kinda like a "construct your own sudoku" type of puzzle.
