Friday Puzzles #143

So dearest reader, I think this will be my last Friday Puzzles here on Warwick blogs. Why not take a look at my facebook page to learn a little more. You can even, like, like it, or something like that, like. How I loathe the word like. Almost as much as I do the word blog.

Anyhow, more news soon, but be prepared to start updating your bookmarks.

On to this week’s puzzle, another itsy-bitsy Akari puzzle. Because of the small size, I feel duty bound to make it non-trivial, but because of the small size, it isn’t anywhere near being too hard. Enjoy!

[blockquote mark-up still apparently not working. The fact this hasn’t been working for a long long long long long long while is a (small) contributing factor in me moving!]

Friday Puzzles #115

Permit me, dearest reader, another week lingering over my LMI test from a couple of weeks back. The Suraromu puzzle I put together was one of the puzzles that was most well-received, which is nice because I put it together very quickly one dark March evening just before bed after seeing this MellowMelon puzzle that I thought was really cool. My puzzle definitely has a pleasing logical path in solving it, but I hoped the fact that I paired this puzzle on the same page as the Numberlink puzzle was not lost by LMI solvers! Sadly, with that constructor’s note I should probably label this only medium, but I hope that you, dearest reader, appreciate the novelty with this one!

Now onto this week’s puzzle. Whilst I have been fully aware of a set of wonderful java based applets from long time friends of this blog, the Jankos for a long time now, I have always been a little reluctant to add an interactive side to the blog so far. This has partly been because I don’t really have that much control over the bare-bones coding of the Warwick blogs system (for example, my recent gripes with the blockquote marking apparently no longer working), partly because of the fiddling around needed with input strings and so on, and partly because I like to have some control over how the puzzles look. A puzzle is still a puzzle even if it has a bit of a facelift, but I’d prefer it if my puzzles retained as homogeneous a look as possible.

Which is why I was rather excited when fellow maths Ph.D student here at Warwick, Rupert Swarbrick, approached me with a little toy Akari web script that he was inspired to write after seeing my puzzle a couple of weeks back.

The script itself is wonderful in that it is very clever, very simple, is fully customisable with its appearance via CSS, and generally makes me very happy! So with all that said and done, how could I not write another lame 10×10 Akari this week? I’d almost say this one was hard, and certainly the configuration here probably deserves to be sent to 11 some time, but as with 10×10 Masyu, I have big reservations about calling any Akari this size hard. So medium it is – enjoy!

Friday Puzzles #113

So I’m a little bit of a rush writing this entry, but let me make a couple of brief comments about how my Nikoli Selection LMI puzzle contest went last weekend. Firstly, I was very pleased to see lots of participation (even with a clash with a German competition) and that nothing went wrong. Reception to the puzzles seemed very warm and I’m glad that there was something in it for everyone.

Special mention has to go to the winner of the contest, Hideaki Jo, who had the main set of 16 puzzles solved in little over half the allotted time, before proceeding to destroy the 3 bonus “marathon” puzzles. I was expecting what with the puzzles being fairly tricky, answer entry and everything else that there was really only a possibility that 2 of these 3 puzzles could be gotten out in time, but Hideaki pulled off a stunning performance to get out all 3. Commiserations should also be offered to Dr. Snyder, who actually had the main 16 out faster than Hideaki (and actually slightly faster than my own test-solving times, which don’t take into account answer entry, and obviously aren’t the first times I’ve seen the puzzles), but tripped up on the larger yajilin puzzle, and could only manage a “mere” 2 marathons in time.

Anyhow, thanks for participating and making the whole thing a great success if you did, and if you didn’t, the puzzles are still up at LMI if you want to try them out. Like I say, if you enjoy the puzzles on this blog, you’ll love the test :-).

Onto this week’s puzzle. A 10×10 akari. Must be rubbish then eh? Enjoy!

Friday Puzzles #74


As much as I’d like to go on about a rocking American band of the 70’s, I think I’d better Keep It Simple, Stupid. Especially in light of recent puzzle-writing dickhead errors on my part. So what could be more simple than a 10×10 Akari?

Well: I haven’t posted the rules before (competent use of the mouse in a leftward direction should help you here); and 10×10 Akari are usually lame. This one isn’t. Enjoy!
