Glad that Picross is finally getting some recognition, I love that type of puzzle. There's just something about staring blankly at a board for 15 minutes, then filling/crossing one square that cascades to solving another huge chunk of the puzzle. For whatever reason, I find Picross puzzles much easier to solve than Sudoku (not necessarily faster to solve, but easier to spot patterns). Only trouble is that I prefer the bigger grids now. When I got a book with Japanese puzzles in it, I just skipped to the last one and solved that first.
