Silly bit of ridiculousness--there are some unclosed parentheses on page 2, in the scoring table.

For Four in One, will each condition be satisfied by exactly one of the variant rules? In particular, it seems that Renban/Meandering *could* match, and Palindrome/Equal *will* match if the lines are even in length.

For Three's a Crowd, does "all of the wrong clues are different" mean that each digit will be represented by an incorrect clue exactly once for each side? (Four incorrect 1's, four incorrect 2's, etc. and one for each side of the puzzle?)

Thank you!

Thanks for your query.
In 4 in one sudoku each line will satisfy exactly one varient.
In three is a crowd sudoku wrong clues are different on each side.
Each side wrong clues will be 1 to 9 once.

These have been "closed" now. Thanks for pointing this out. You can download the latest IB.

Adding to Kumaresan's reply,

Timjamiller - 2020-08-24 11:50 PM

For Four in One, will each condition be satisfied by exactly one of the variant rules? In particular, it seems that Renban/Meandering *could* match, and Palindrome/Equal *will* match if the lines are even in length.
There will be a unique way to assign each variant to a different line. In particular, a renban will always satisfy meandering diagonal rules. In the IB example, both the lines at the top satisfy "equal parity" rules. But there is only one line which satisfies palindrome rules. Similarly both the bottom lines satisfy "meandering diagonal" rules but there is only one which satisfies renban rules. Hope this makes it clearer.

For Three's a Crowd, does "all of the wrong clues are different" mean that each digit will be represented by an incorrect clue exactly once for each side? (Four incorrect 1's, four incorrect 2's, etc. and one for each side of the puzzle?)
What you said is correct, assuming all clues are given.

Can you share solver usage instructions as well. For whole 90 minutes I could not figure out how to clear a specific pencil mark. For eg if I have 123 pencil marked in a cell and I want to clear 1. Then how can I do that?

..... A really tough set, but enjoyed thoroughly! I found Parity skyscrapers and X-Anti-windoku as most difficult. And felt arrow-thermo 50:50 was the best per construction. Thank you Kumare-san!

Hi all ! With the lockdown contest over now, we have published a video on X-Antiwindoku from the contest on the channel "Unshackling Sudokus and Puzzles". This sudoku had the least number of submissions and caused difficulties to a lot of solvers. Do check it out if you are interested to know how it could have been aced and also how to solve it like a pro if you ever see one of the same variant again in the future :)
