Some solving steps for Puzzle 499, a bit about LMI, and some other stuff

I am attaching a mini-walkthrough PDF for the Arrow Sudoku I posted for the league recently. Its a bit rushed, and only takes the solve through the more difficult deductions, but should be really helpful if you were stuck on that Arrow Sudoku or didn’t attempt it but want to know more about the variant in general. Here’s the PDF –

Now, a bit of a plug. Want more walkthroughs? We do much more detailed ones for LMI patrons. Also, I should say that, at least currently, supporting LMI would mean you are supporting my personal goals too (which is why I don’t have any such effort for this blog).

Also, I might have to disappoint any fans of milestone puzzles by saying that I currently don’t have anything planned. But you never know right? Maybe I think of something worthwhile in the next few days. If I don’t, then come Saturday I’ll just post a League Sudoku as my 500th and that’ll be that.

Soon I’ll be shifting residence, so I’m generally a bit more busy since I want to finish a bunch of things before I probably lose internet access for a week or two.

Puzzle No. 499 – Arrow Sudoku [Daily League]

This puzzle has a nice application of group-thinking… I think. The solving path is also pretty narrow. Not something I’d advise for beginners.

Remember that you can solve the puzzles from the League online on the Sudokucup Guest League page with a 24h delay.

Rules – Follow regular Sudoku rules. Additionally, the number in a circle is the sum of the digits which are covered by its arrow. For circles with multiple arrows, apply the rule for each arrow separately.

Rated – Hard.

Enjoy!

Puzzle No. 495 : Arrow Sudoku [Daily League]

Update: Puzzle had 2 solutions. Fixed now. Apologies.

Just about got in a Wednesday post.

Remember that you can solve the puzzles from the League online on the Sudokucup Guest League page with a 24h delay.

Rules – Follow regular Sudoku rules. Additionally, the number in a circle is the sum of the digits which are covered by its arrow. For circles with multiple arrows, apply the rule for each arrow separately, where some arrows can have some cells in common. (e.g., 1-2-3 and 1-2-1-2 are valid sums for a 6 in a circle, with the starting 1-2 being common).

Enjoy!

Puzzle No. 483 – Arrow Sudoku [Daily League] + updates

A few things –

If you haven’t already, please like/tweet/comment for my blog here (if you like my puzzles of course). The blogging awards will be handed out in a public ceremony on the 9th of February (you can find out from the link how to attend if you want to) and some publicity for what we do is always a good thing.

The blog will now be divided into 3 main tags.

1 – Daily League – Medium to difficult mostly-variant Sudokus.

2 – Ex-Contest – Although I won’t be releasing everything I contribute to Championships free anymore (more on that later), I’ll release some of the smaller doses, like when it’s not enough puzzles to make up an entire set.

3. Instructive – I am working on a curriculum for puzzles, and as a result, I feel the need to put some easy puzzles and some preview of tips and so on, without giving the entire content away of course.

I will be linking to this post in the future for reference about the tags. Hopefully I’ll post 2 and 3 tomorrow and day after itself to give a full view of the plan going forward, but can’t be sure of that as I have travel coming up. Definitely within the week.

Now to to the Daily League.

First, PDFs!

Puzzle No. 439 : Arrow Sudoku [Daily League]

I’ll be posting about a Championship and my puzzles in it tomorrow. For now, I didn’t want to crowd up this post.

Remember that you can solve the puzzles from the League online on the Sudokucup Guest League page with a 24h delay. Speaking of Sudokucup, much thanks to Karel for providing this version of the image, with the arrowhead present in the circle. I think it provides more clarity than the version I had drawn up before it.

Today’s Sudoku was quickly put together because I couldn’t really get much time to think for it. That, in general, seems to be a good thing, because I always over-think things these days when it comes to picking variants/puzzles/themes that I want to do. Not sure why thats happening now.

Anyway,

Rules – Follow regular Sudoku rules. Additionally, the number in a circle is the sum of the digits which are covered by its arrow. For circles with multiple arrows, apply the rule for each arrow separately.

Rated – Medium (I think). 

Enjoy!
