The number in the clue is greater than the other cell for ALL given clues

OR

The number in the clue is smaller than the other cell for ALL given clues

In practice material Scattered Sudoku. After entering 5 at R2C5, 2 at R8C9 , non of the colored cells can contain 2?

Thanks got it Deb and Rakesh :)

hie
i think entering 5 at r2c5 itself is a wrong step , in that row 5 can be at r2c8 :)

Does the Sudoku XV in the IB have 2 solutions? I have a different solution and I don't see any mistakes in it.


In your different solution, have you taken into account that there must be a specified number of corresponding digits per row in both grids on the same page?


Ah! No, I had not. I am notoriously bad at reading the full instructions ... even as I wondered what those numbers in the middle were doing there ...

I attempted the chaos renban only after the test...and found it to be easier than some puzzles worth 30-40 points. I know it can vary with individual strengths, but that's a hell of a lot of variation!

I agree. The chaos renban took me 10 minutes, while the other 100 pointer, x is alive took me 20. There's a few others that I think are incorrectly valued too, but the chaos renban is probably the biggest sore thumb I saw.

Points distribution is mostly a very hard part of writing a test. I am lucky to have a small team of testers, who are all well experienced sudoku solvers. There is quite some variation between their timings, so I understand the responses here. Especially the Chaos Renban puzzle has a shortcut that makes it easier solvable; the 5's play a crucial role in all five renban groups. Noticing that makes the solving process a lot faster.

It is always worth looking to high pointers in a test, even if you are not among top solvers. It might be better to look at puzzles that you are good at, no matter how much points they are worth.

These tests are always made to be printed. Puzzling is in general a paper and pencil activity (although I admit some of that is changing). So being without a printer will always make it a bit harder to solve. I don't exactly see what makes it unfriendly though. It might take a little bit more time writing in paint, but I don't see how that can be changed fairly. I for example aren't very skillful in online applets, so that would not give me any advantage if those were made. But I generally feel that some people get a distinct advantage of solving in an online applet as they employ a solving style that would be very impractical on paper.

I personally don't have a properly functioning printer right now. So I did it without a printer in paint. I thought it went pretty well. I would have probably done better with one as it's much easier to write and keep notes and write quickly on paper than in paint. But the grids were easily copy-pasted into paint two at a time because of the layout, so it saved some time in having to copy paste all grids separately. I could solve 2 puzzles and then put in the answer keys 2 at a time, saving me some time in having to switch windows a lot. I did last week's test in paint as well and I thought this one was much friendlier in having to solve in paint.

The only complaint is that there wasn't online solving. It is unconvience for people without printer.
