How Old Miles and I develop an idea- sequel: take cover

(Eingestellt am 14. März 2021, 07:15 Uhr von bigger)

You might think it's the same three idea all over again. But this time, it's going to be really hard. The idea comes from Mark Sweep.

The thing is, it remind me of a type call sum after 1 (or any digit). You can find similar ideas with A-sum tag, which is sum before A.(why that name) So like before, I just need to swap the sum part out with other ideas. But, why 1? Of course it can't be any digit behind any digit, which is an rediculously undoable idea. There came the idea of parity.

Digits outside the grid is the first digit behind an even digit.

It's tough. So the idea must be complicated to be easy. So comes this.

Digits outside the grid is the first digit behind the first even digit.

This puzzle is made by Old Miles from China. If you really want to solve it logically (I use a lot T and E), I could give you an easier version with given digit. Ask in the hidden comment.

the other way we develop an idea basically is bringing in uncertainty. It can be fully uncertainty like the n-sum, or partial uncertainty like parity. The thing is every change of the rule should affect the tricks solver used and the experience they been through. You might notice all the puzzle I post have cohesive rules. When you understand the rules, you know where to start and how to start. When checking the fragile puzzle rules, by the time one understand the rules, the tricks flood in. Now this two puzzle is the opposite. It's easy to understand, but one can get barely nothing about the tricks. I think I push that idea to its limit. Hope you also enjoy this explore.

By the way, you guys should check out Timwi. We are not that much fans of calculation. Old Miles said when a puzzle has to deal with calculations, it's audience would be scarce, in China. So he wouldn't make a variant on neighbor sum. If you are interested in what would happen when neighbor sum has uncertainty, Timwi's puzzle would be interesting to check out.

Lösungscode: row 4 column 4 of the first one then second one (24 digits)

Most of your first paragraph has disappeared. You can replace the ampersand with `&` and then we can see what you wrote.

Bigger: Oh, I didn't notice that one. Thanks.

Update rule explanation. Now I think of it, the second one is a lot like glum hippo's parity party.
