Sorry, I did not realize that the Sudokus were “Just One Cell” Sudokus.

Just to check further, B9 appears to be an invalid puzzle in the instruction book (several cases of repeated digits in boxes, unless I missed something on that one).

The shape of regions should be 3X2 instead of 2X3.

Check the Instruction booklet. There's a reasoning there. Screen Tests are designed to test visual skills. We've made an effort to make the difficulty easier this year, but I think its important to keep this a visual skill based test.

It basically means that, for the rule that says "if X is there, then Y should happen", you should also take into consideration "if X is not there, Y shouldn't happen". Take XV for example, if there is an X between 2 cells, then the sum of those cells must be 10. Because converse rule applies, if there isn't an X between 2 cells then the sum cannot be 10.

A question about scoring:
- Each sudoku is worth points varying from 25 to 200.
- The exact point will be computed after the test is completed as “average of 30 best times (in seconds) for that sudoku”, subject to the minimum and maximum values.
I’d like to know how the exact point will be adjusted from 25 to 200 if an average time is less than 25 seconds or over 200 seconds.

I know this is a lot to ask, but is it possible to make the applet less sluggish in the future? Moving and typing feels very slow compared to Nikoli. Also, can you implement backspace as delete as well?

Does the 15 second waiting time before each puzzle (which you can skip according to the booklet) count for the total time?

For B2, does it mean that at least two of the squares adjacent to a shaded square contain the same number? It's not quite clear from the description; can anyone post a fully solved Repeated Neighbors Sudoku puzzle (obviously not the one in the IB)?

It does not count in your total time.

Hey Yuhei,

25 and 200 are the minimum and maximum values. i.e. no Sudoku will be less than 25 or more than 200 points.

Yup thats what it means. But note the converse rule too. More than just solution, there's a way to look at an entire solve by going to the Sudokucup Guest League page and seeing others solve my Repeated Neighbours on 24th July

Thanks for bringing it up. For future contests, we will have a close look at the user-interaction part to see what can be improved. I hope it is equally bad (or good) for everyone.

I want to have been informed that "there are Only-one-cell problem" beforehand.
I was really confused with some of the problem by the lack of the information.

It has been mentioned in the Screen Test Guide. I'm sincerely sorry about your experience, but it was definitely informed.
