Puzzle 139 – Tapa [In/Out]

This is a Tuesday tapa puzzle, with the exception that cells with numbers are allowed to be shaded or unshaded. Note that a cell with a number will never count itself, only the eight cells around it.

Puzzle 109 – Tapa

This is a Monday tapa puzzle. The ordering in clues is just for aesthetic purposes, so for example, treat a “3 1” clue the same as a “1 3” clue.

Yes. I know. It’s very easy, but it worked out very nicely and symmetrically and I thought it was cute.

So, things I have been doing during this interim:

I finished making mathgrant’s Battle of LITS for Board Game Arena, to be released in the middle of December. I’m very excited about this, because this was a project that I didn’t entirely expect to be able to complete, and I’ve never done any big project that will be publicly available to so many people like this before.

I also learned Unity, and started to make a copy of my Puzzlescript game, Snakeoban in it. (Although it was very good for learning how to use Unity, I doubt I’ll continue with this. It seems more interesting to use it to make a game which isn’t already playable online!)

I’ve also started college! This is obviously making me quite busy in addition to everything else, and also tends to take first priority. However, I at the minimum still have a full week of five themed puzzles for this week.

You can likely figure out what the last main thing I’ve been working on is by this week’s puzzles’ theme! (Well, if you’ve been following my site for long enough, that is.)

Puzzle 76 – Tapa [unique clues]

This is a Friday tapa puzzle, however, some of the clues have been omitted and replaced by asterisks. Every asterisk must be replaced by a positive integer (which consist of the set {1,2,3…}, but not 0) of positive integers, such that every possible clue appears at most once in the grid. So for example, there cannot be two “1 3″ clues. I didn’t want to actually put asterisks in all the squares though, in case you want to write notes in that square, so I made two versions as a solution to this. Both are the same puzzle, just different presentations.

What? 5 consecutive puzzles actually posted on the correct days without any broken puzzles? It’s been a while since the last time that happened. I guess it’s because I just like this variation a lot.

Puzzle 74 – Tapa [unique clues]

This is a Monday tapa puzzle, however, some of the numbers have been omitted and replaced by question marks. Every question mark must be replaced by a positive integer (which consist of the set {1,2,3…}, but not 0), such that every possible clue appears at most once in the grid. So for example, there cannot be two “1 3″ clues.

This puzzle has got some really nice symmetry, and interesting logic too. I really like how it worked out. I have one last unique clues tapa coming on Friday, too.untitled
Lastly P.I.HUNT 1 is in 24 days. Last year, from P.I.HUNT 0, the beta test, I learned that I have to make puzzles quite a bit easier, as people familiar with logic puzzles do not necessarily do hunt-style puzzles. So this year, half of the puzzles will be introductory, for people who haven’t seen hunt-style puzzles before, and half of them will be more difficult, so that you can play along no matter your prior skill level.

Puzzle 72 – Tapa [Unique clues]

This is a Monday tapa puzzle, however, some of the numbers have been omitted and replaced by question marks. Every question mark must be replaced by a positive integer, such that every possible clue appears at most once in the grid. So for example, there cannot be two “1 3” clues.

This is a very interesting variation, which was made by Tapio Saarinen on GMPuzzles, but only one puzzle of this type ever was shown, so I think this week should be interesting.

It’s also worth reiterating that zero is not a positive integer.

Puzzle 61 – Tapa [Mastermind]

These are two Wednesday tapa puzzles. In between the puzzles there are mastermind clues. This means that they add up to the amount of corresponding cells in the two puzzles are either both shaded or both not shaded. In particular for this puzzle, an ‘8’ means that those rows are identical in the two puzzles, and a ‘0’ means that those two rows are inverses of each other.

In last week’s third meta, at first you might have thought there was a typo, as “carries” is a common word, but “caries” is much less commonly known. Normally, if you find something odd in a meta, you’re usually on a good track. In fact, each of the words can have one letter added without changing the pronunciation. Taking the extra letters, “wHine”, “browsE”, “caRies”, “aDd”, which leads to the word “HERD”, however this isn’t correct. Applying this process once more, gives the thematic answer “HEARD”.

Puzzle 56 – Tapa [META]

Alright, I’m finished playing with formatting. I really liked the old theme I had, but it kept randomly deleting posts and messing up my formatting…

This is a Tuesday tapa puzzle. This is different from a metatapa you might have seen if you took the USPC this year. Instead of oddly shaped grids, the grids are regular. The positions of all the clues are given to you, but there is only one way to set each all of the clues to make a unique tapa puzzle. If you are still confused, see the example below:

In the example and the first puzzle, it could be possible to just check each of the 5 and 115 possibilities respectively, but the last puzzle has way too many to check (12167) without using logic. I included these two puzzles because the first might give insight on solving the second. If you want a challenge a bunch harder than Tuesday level,  start with the bottom one.

Puzzle 42 – Tapa [Möbius]

This is a Tuesday tapa puzzle, but in the shape of a mobius band. In other words, The left side connects with the right side, flipped vertically. See the diagram to understand better. Above the diagram, “0123456789” is shown, so you can see the font used.

Remember, coming this Friday is  P.I. hunt 0. It will be a shorter/sample version of the puzzle hunt starting on 3/14/15.

 

EDIT: originally posted a draft of this puzzle, instead of the working version.

Puzzle 17 – Tapa [KNAPP DANEBEN]

This is a Tuesday tapa puzzle, with a twist. EVERY number in each clue is wrong, and should actually be one more or less than written.

This is an actual Knapp Daneben, after yesterdays psuedo-knapp daneben. Hope that makes up for that.

I think this is the first puzzle I’ve made in a while with 8-way symmetry. (D4 group symmetry if you know what that means)

EDIT: Just a note that a 1 in a multi-digit cell can not become a 0.
