Puzzle No. 494 : Inner Tripods Sudoku [Daily League] [Invasion]

Greetings from another universe! After the Prasanna from your universe wrote a contest for LMI based on a few variants from our universe, the Inter-Dimension Puzzle Wizard notified me of the same. I decided to launch a translation of your wacky variants and a clarification of what you call our normal variants, for the people of my universe who might want to solve these Sudokus. The Prasanna from your universe was kind enough to include this as a separate “TheirUniverse” PDF.

That gave me an idea that I should probably write a Sudoku for something, featuring another one of our variants that has the same name as one of yours. Me and the Prasanna of your universe went through the list of variants in my universe, and he liked our version of Tripod (Again, your version is so wacky, but interesting), so I wrote a Tripod that we decided to use for the Daily League!

Your universe’ Prasanna got a chuckle out of this fact, but in our universe, “almost” symmetric puzzles are considered as having better aesthetics than fully symmetric puzzles. Maybe someone is interested in this fact, and in the Sudoku I wrote.

Rules – Rules for Sudoku. Additionally, in the grid there are “tri-pods” with a “seat” and 3 “legs”. The seat, and the “feet” of the legs are denoted by dots. The “seat” of a tripod must have a digit thats greater than each of the “feet” but the sum of the “feet” must be greater than the “seat”. Digits can repeat in a Tripod.

Enjoy!

Puzzle No. 484-487 : Polish Qualifier Puzzles [Ex-Contest]

Check this post for reference on this blog’s 3 main types of posts from now on. I’ll post smaller sets like this one here, and keep I’m hoping to start a patronage system of my own for bigger sets. More on that later.

Right, just about got this in today. I won’t be home over the weekend, so whether I get a sample of the Instructive tagged post out depends on getting an internet connection where I’ll be staying. I’ll be back on Monday though, so will have it up at latest by Monday night.

This set might seem to have some tough puzzles for a National qualifier (not finals), but I was told that there were many easy puzzles already. Two of the puzzles are types I saw in a book purchased from team Japan at the WPC. It is a collaborative work featuring Serkan Yurekli and many Japanese authors. I’ve changed one rule slightly for Heyawacky block (more an omission than a change) but I prefer it this way personally. Anyway, here they are. Enjoy!

Rules –

484 – Yajilin.

485 – Heyawacky Block – Blacken some cells so that all remaining cells must be connected orthogonally. Any single horizontal or vertical line of white cells cannot traverse more than one thick line. Numbers indicate the amount of black cells in that region. If there is no number, there can be 0 or more black cells. Inside each region, all black cells are connected orthogonally. But black cells must not be orthogonally connected beyond the border lines.

486 – Nurikabe.

487 – Snake BY – Draw in the grid a snake, not touching itself, even diagonally. Each outlined region must contain exactly 3 cells occupied by the snake. The regions that contain the head and the tail of the snake are marked by grey color.

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.

Been absent for a week, due to a few health issues. I’ll be back to normal now hopefully (since me saying that seems to curse me into inactivity again so many times recently). The below Sudoku is probably trickier than the rating, but as with most XVs, it’ll probably zoom through once the starting bits are deduced.

Rules – Follow regular Sudoku rules. Additionally, two neighbouring cells containing digits adding up to 5 are always separated by a V. Two neighbouring cells containing digits adding up to 10 are always separated by an X.

Rated – Medium (+).

Enjoy!
