A wonderful set of puzzles (not counting mine; it's unfair to judge my own puzzle). Mostly. Except for Twin Co-Ordinates, because I loathe visual puzzles. But that's about the genre; the puzzle itself is fine.

Each puzzle has its own pros and cons. Those that are the most interesting for me are shown in the table above:
- Hidoku: Still a wonder on how to make these so well. I still remember four years ago when Palmer said he wouldn't make more Hidato/Hidoku puzzles, though: https://mellowmelon.wordpress.com/2012/05/27/puzzle-pack-3/ :P
- Spiral Galaxy: Totally not because my time is under 15 minutes. But as usual, nicely constructed Galaxies puzzles are always a wonder to solve, on how really unusual/large regions can span across the grid.
- Pentopia: I'm not sure why, but I just find this one nice to solve. This is a close call, actually; fighting for this spot as well are Hex Slitherlink with its nice pattern (although impure, like this Pentopia), LITS+ with interesting logic around, and Domino Loop that's also pleasant to solve.

Now that I know the real rules of Poset Futoshiki, I am not very happy with the example. I thought that "X < Y" means I can only place numbers X and Y which are connected by an arrow. The fact that I can jump over numbers was not very clear.


Yes, this part is unfortunate. I was hoping that people would have tried the Poset Futoshiki fun contest that was just a month ago (mostly for its better example), but I think I forgot to tell people to do that. On retrospect, I should have used a larger example (2x4x4).

LPF just flowed so nicely. No big pauses. Just fill it in. Didn't really like Akari. I'm not a fan of Akari to begin with, but then I thought too much trial and error due to not much overlap between number clues.

Hi, I'm new to this and I'm a little confused by Linked Poset Futoshiki. I see that there are 4 rules to this puzzle:
1. Assign one of the 3 diagrams to a small grid
2. Solve each small grid so each number appears once every row/column
3. Make sure all >/< signs are complied
4. Digits separated by gaps must be identical.

I get 2,3 and 4. But I don't understand no.1. How does the diagram relate to the grids? What do the diagrams mean?
Sorry for the very newbie question, and sorry if this is in the wrong place. Found this puzzle via Reddit.

Lets look at the example below. By "diagram", we mean one of the trees (colored for your reference).
So, each small grid (3X3 in the example and 6X6 in the actual puzzle) will be assigned one diagram.
i.e. the "Inequality" rule in each grid will be governed by the "tree diagram" associated.

If you look at the solutions on the right, the top left and bottom right grids are assigned with tree diagram marked as "Maximum". Similarly, the top right and bottom left grids are assigned the tree diagram marked as "Minimum"

If something is still not clear, let us know.

I enjoyed basically every single puzzle except for the twin coordinates one - it didn't feel like a logic puzzle at all, although I seemed to have guessed correctly which squares "should" have doubles. Not sure if that was the idea? Might have missed the point of it.

Different people have different strengths and weaknesses. Maybe you are better at spotting/guessing similar doubles.
Most of these puzzles are types that frequently occur at the World Puzzle Championships (WPCs), and there have been visual-based rounds (like Screen Tests) often in the past.

I disagree with you about TCO not having any logic. There are certainly cells/areas you can cross out and gradually get the pairs one by one by reducing the pool of potential cells, rather than randomly surfing through the grid.

The word "Poset" is short for "Partially Ordered Set", which means that there is some sort of "less than/greater than" relationship,
but that not every pair of items can be compared.

Example: Let the set be the Simpson family: kids Bart, Maggie, Lisa, parents Homer and Marge, plus Homer's father Abe.
Let our "less than" stand for "is descended from".
Every child is "less than" each of the adults, but none of them can be compared to the other (neither Bart nor Lisa is less than the other).
Homer is less than Abe, but Marge is not less than anyone in the family.

For Futoshiki purposes, that means that if you have a less than sign between two cells, they have to be a pair that is comparable (at all) and in the order indicated.

In the diagrams, arrows lead up from lesser to greater, and the relationships are transitive (so A < B and B < C -> A < C, as is true in the Simpson example also).

please clarify

In the example, look at the 3rd column of the first box and the first column of second box. They are separated by a gap and are identical. Similarly look at the 3rd row of the first box and the first row of the third box. Again they are separated by a gap and are identical.
