Crypto Japanese Halligen for Gliperal
(Published on 4. June 2023, 06:51 by KNT)
Ships are to be placed in some water cells. A colored water cell is called a lighthouse, and ships may not touch lighthouses or other ships, even diagonally. Lighthouses may only touch other lighthouses diagonally.
Place numbers from 1 to 9 on every island cell, ship, and lighthouse such that no number repeats in a row or column, or on an island. No water cell may contain a number. Clues outside the grid indicate the sums of connected groups of numbers in the respective row or column, in order, where empty cells serve as delimeters between groups.
A number on a colored cell on an island indicates the size of the island containing that cell. A number on a lighthouse indicates the total number of ships that share a row or column with that lighthouse.
Eleven of the twelve letters in outside clues replace unique numbers from 0 to 10. The letter that replaces 10 never appears in a two digit clue. The last letter replaces a different number from 0 to 9 in each occurrence. A question mark can be any number from 0 to 9, and for all clues, none may have a leading zero.

Solution code: Row 11, Column 11. X for empty cell, and S after each ship cell.

An absolutely brutal masterpiece! What great fun to solve it during free time over two days. KNT is something else when it comes to seeing puzzles. Thanks a lot for sharing this masterpiece.

A quick clarification please # can the ‘irrwisch’ take the value of 10 or should it always be digit?
—- Above may be ignored. It has to be a digit.

I can't *believe* it didn't occur to me to do this 4 weeks ago. New solvers! In this comment section... I present... to you... the full rules of halligen... IN ENGLISH!
Each cell in the grid is either land or water. There are no 2x2 of water, and all water are orthogonally connected.
Some water cells can contain a "lighthouse" or a "ship". If a given clue (denoted by a star in this puzzle) is on land, it counts the number of land cells in its maximal connected group. If a clue is on water, it represents a lighthouse and counts the total number of ships in its row and column.
Ships can't touch other ships and lighthouses, even diagonally. Lighthouses don't touch each other orthogonally, but may touch diagonally.
Have fun solving!

I used 6 colors for notating -- land, non-digit, water of unknown type, digit of unknown type, ship, and non-ship. I think I did okay.
As usual, I did not manage to complete a KNT birthday present in under 4 hours.

@Silverstep: No, the clues are in Base 10, and the digits in the grid are from 1-9. The letter that replaces the value '10' will always appear by itself.

Rules clarification: How does the digit "ten" work? Are the clues written in base-11?

Would be helpful if you posted the rules for halligen. The link comes up in German.

Happy birthday Gliperal, I hope you and others on the portal will enjoy this masterpiece! I really enjoyed testing it, there's a nice flow of beautiful and surprising deductions in typical KNT fashion, nothing was noticeable hard but it will require a good strategy to annotate the grid.
