Yes, DNA Cool (Palindrome/Look-And-Say Hexuro)
(Published on 7. August 2026, 17:54 by Nell Gwyn)

I made this for a live Setting Saturday event at SudokuCon.
- Hexagonal Kakuro: Place a digit from 1 to 9 in each empty cell such that digits do not repeat in an unbroken line of cells with no black hexagons separating them (along any of the three directions in which cells share edges).
- Clues on black hexagons indicate the sum of all the digits that clue sees in the indicated direction, up until either the next black hexagon or the edge of the grid.
- Palindrome: Digits on a gray line must read the same in both directions (the center of each line is marked with a dot for clarity).
- Look-And-Say Cages: A clue in the corner of a dotted cage describes how many of certain digits appear in that cage. For example, a clue "1321" is read as "1 3, 2 1" and means that the cage contains (exactly) one 3 and (exactly) two 1s.

Solution code: The five digits after the black hexagon in row 2 (read left to right), followed by the five digits after the black hexagon in row 6 (also left to right).
