Ah, yes, Puzzle GeneRator JaPan, the reason why my production of Sudoku puzzles on my blog slowed down significantly. When I discovered that you could program a computer to generate a puzzle with the givens in a specific arrangement, and even specify some of the givens from the outset, I felt like there was no point in making Sudoku, since it was now going to be much, much, much harder to come up with something truly brilliant or interesting. o_o;;

Fillomino currently seems safe, though.
