Are you sure you're using the correct example for Palindrome? The example in the WPC IB is very different, and that one has the correct "two cells with different letters are not separated by thick line" rule.

We missed the example in the last version, that has now been replaced with the correct one.

I don't understand the sentence "Each row and each column of subgrids form palindromes." For example in the middle column, the top subgrid only has CB, which is not a palindrome (though if you take the whole column it is a palindrome).

There is only one subgrid - the3x3 box. The other grid is the complete 6x7 grid. For both, the palindrome rule "Each row and each column forms palindromes" holds.


So how do we know whether the whole grid should count as a trivial subgrid or not? In the new example, the rows of the whole grid are not palindromes.

Just ignore my previous reply. It was a wrong example. The rule holds only for subgrids - as mentioned in the rules.

Thanks -- the example in the new IB makes more sense.

Question regarding results: is there a good reason why there is only a "potential results" page rather than the usual page showing everyone's scores to everyone who has finished? I understand instant grading is not always desirable, but since this doesn't seem to involve any optimizers like Riad's contests, having one's score available at the end of the 110 minutes shouldn't be problematic and would be nice to have...

Because the contest lasts for the whole week, not just 110 minutes.

Ah, I see. I got confused by the mix of instructions, some of which suggested it would run as a 110-minute contest, or as the usual marathon, or all week. Now it's clear :) It's being run in Riad-contest-style, and the results are non-announced in Riad-contest-style. Makes sense.

Consider the 26 in the top left corner, and what will happen if it goes to the right, between the 20 and 7.

This should tell you a lot about where the 26 does go, and you can then use similar logic for the 20 for even more of a start.
