However, those who are underwhelmed by the whole Sudoku craze should still pay attention as the Xtra part of the title holds equal prominence. There are several nikoli-style puzzles in each issue, along with some other WPC favourites. And not to forget arguably the most interesting bit, the community section. (Of course I can’t claim to be totally impartial here!) This features a really rich and diverse collection of logic puzzles sourced from professionals, amateurs and experts alike.
OK, that’s quite enough plugging for now! This week’s puzzle is another Suraromu, inspired the puzzle that appeared in the latest issue of Sudoku Xtra, which was about as much fun I’ve had with any logic puzzle I’ve done in a while. I’m not sure this one rises to those standards, but It’s certainly non-trivial. Actually, Suraromu as a puzzle type intrigues me somewhat because much like Numberlink, as the difficulty of a given puzzle rises, so does that puzzle’s susceptibility to uniqueness strategies. This is certainly true of this puzzle, but unlike with numberlink I think I’d suggest to the puzzler wanting most satisfaction out of the puzzle to resist temptation this time around. And I think I’ve babbled on for long enough now, so all that remains to be said is, Enjoy!
#148 Slalom – rated mediumP.S. I should remark that I’m not entirely happy with the presentation of this puzzle. There are some squares which share gates, and I thought that during the test solving this might be a little misleading, even if it is at least implicit that every numbered gate has both of its “posts” labelled. My solution previously had always been to employ a convention that there should be no squares sharing gates, but I suppose I got a bit lazy this week. I’d be interested to know people’s thoughts on this one…
