Crypto Japanese Cave (2)
(Published on 13. October 2022, 23:25 by KNT)
Shade some cells such that all unshaded cells are orthogonally connected, and all orthogonally connected groups of shaded cells touch the edge of the grid.
Clues outside the grid indicate the sums of connected groups of either shaded or unshaded numbers in the respective row or column, in order, where numbers in cells with the opposite shading serve as delimeters between groups. All the columns are for one of either shaded or unshaded, and all of the rows are for whichever type of shading the columns is not.
The letters A to H replace numbers from 0 to 9, and no two letters may replace the same number. A question mark can be any number from 0 to 9, and for all double digit clues, none may have a leading zero.

So proud of this solve. I lost count on how many times I have broken it during the last couple of months.
Great logic and solve path. Thanks KNT

Finally !!!
After several month of trying to solve this one, I have finally spotted the crucial piece of logic that was missing to get into this puzzle :)
Amazingly good opening sequence !
Now I can move forward to the next in the serie ! A lot of catching up ahead of me :)

An absolutely amazing solve! I had many pitfalls by forgetting the 0 can change all Japanese sum deductions, but climbing out of them and finding the right path was definitely worth it.

Updated visuals: using "?" instead of "." for better visibility

Way better than the first one ;)

Brilliant construction with a very challenging and engaging solve path till the very end!
The 0 really adds an extra layer for the solve, and there are plenty of unexpected deductions in the beginning and the later half, I really enjoyed them overall ;)

Every letter and digit obtained are worth it.

Thanks for this challenging puzzle. The "0" definitely adds a dimension to the diff.

Even better than #1! Loved the arithmetic logic in this one. Thanks KNT :)
