Cake by the Lake
(Eingestellt am 20. Juli 2024, 00:00 Uhr von marty_sears)
Happy birthday to Lake, a fantastic setter and top bloke, who I am actually gonna meet in person today for the first time :) This puzzle is also in response to a prompt from gdc to set something with shaded cells that all act as some kind of modifier.
Rules:
- Normal sudoku rules apply.
- Colour some cells green (land) and some cells blue (lake). All cells of the same colour must be orthogonally connected. A 2x2 area may not be all land, but it might be all lake.
- LAKE: Lake cells must not touch the edge of the grid. The value of a lake cell equals its row number plus its column number, regardless of what digit appears in that cell. Eg: If r4c2 is lake then its value is 6.
- CAKES: The value of a cake cell indicates exactly how many cakes have that value.
- SAME DIFFERENCE: Adjacent values on a turquoise line always have the same difference. This difference must be determined for each line.

The level of care and detail you put into your birthday puzzles is nothing short of remarkable. Phenomenal.

Awesome as always. I missread the rule that the border is all land... then its more complex :-). Rereading the rules made a lot suddently clear and 3 star is ok to me. What a joy solving thx once more.

Very nice submission for the prompt. Liked the choice for shading rule and the modifiers. Also really cool interactions with the same difference lines.

Quite a bit easier for me than the rating but might just be hitting my strong suits. Probably my favorite puzzle this month! Lots of deductions I wasn’t expecting when reading the rules.

Wow, that was super fun, fresh and clever! But definitely no more than 2* in my opinion. In mid-solve I thought I had broken it, but then noticed that I hadn't finished reading the sentence in the rules about 2x2. I had just assumed it's the normal yin yang.

Perhaps you wanted to say that a 2x2 area can be completely land, but it cannot be completely water. Otherwise, I don't understand... After all, according to the rules, water can be in a very limited area of the grid. It must be an interesting sudoku. But I can't understand the rules yet...
Marty: No, a 2x2 may not be completely land. But it might be completely water. I'm not sure what you mean about water being in a very limited area of the grid? (to clarify, the value of a water cell does not necessarily equal the digit in the cell. So there might be a 7 in r1c1, but it would have a value of 2 rather than 7, for the purposes of the line its on.) Hope this helps?
