About the Bonus and Points Structure :

The bonus structure this time is bit complicated, but it was necessary to make the changes based on the discussion during last year's marathon. While I think most of the important discussion points are covered, it may be possible that I have missed something. Players are requested post if they see a problem with the bonus structure, preferably before the test starts, so that we can modify if needed.

Please note : The solution for Nanro in the IB has a missing 1 at R3C4. (Rule : All regions must contain at least one number).

(Updated IB uploaded at the time of this post)

For Araf, does "between" mean "strictly between" or "strictly between and including"?

It is just STRICTLY BETWEEN.
If you have clues 3 a 7 in one region, its size should be 4, 5 or 6.

Answer Key Updates

Please note the following updates about answer keys

1) Mintonette now has same answer key as Masyu and Maxi Loop - "For each marked column, enter the lengths of the longest vertical path segment."

For the example below, the answer key is : 72121
Also note that there could be gaps in columns. The answer key should consider the full column.

(Not a valid puzzle. Just for answer key illustration.)

2) Gapped Kakuro

Some players mark circles on Gapped Kakuro and the given circles for answer keys may get hidden if you are not careful. So we have decided that we will provide another way of marking the answer-key cells.

The pdf will have the same puzzle twice, in 2 pages. Once with circle and another time with shaded cells. Please use the formats that is convenient to you.

3)Enter Unit digit only

If any row/cell has a double digit answer key, only the unit (right-most digit) digit should be entered. (This rule is applicable to Masyu, Maxi Loop, Graffiti Snake, Mintonette, Araf).

Puzzle Marathon has started, with 8 puzzles.

Check the submission page, once you click on a puzzle, the puzzle name appears below the table with a start button. Once you start it, the timer starts and the password is displayed.

I have two doubts regarding "Liar Diagonal Slitherlink" as below

1. Can I assume that all the numbers will be given for this puzzle. If not how liar square will be decided among no hint squares?
2. For the liar Square can the number of edges used be equal to given number if we don't count diagonal connection. e.g for a liar square having 2 can put link like Z i.e. using two edge excluding diagonal?

1. Just in response to the question part, its possible to determine the liar square. Due to the all rows and columns need to have exactly one liar constraint, even if there's just one clue in a row or column, that clue has to be a liar, or of course there's say just 2 clues and you prove one is right while solving. For example, the Liar Slitherlink in the IPC did not have all clues given, and I guess the striking out the liar part doesn't change the possibility of a Liar being determined.

2. No. The square once determined as a liar, has to be wrong.

So if I take more than an hour I can't submit an answer? For multi-skyscrapers I see a red X. I cannot find errors in my solution.

So I feel stupid now. Got myself massively stuck on one puzzle, and blew an entire 4.5 hours on an "easy" one. Finally cracked it, but it did raise a question. Is there a way to abandon a solve that you just don't think you'll ever complete? I couldn't find a way to move on and try a different one, so I was stuck using my entire day's time banging my head against a faulty bit of logic.
