In or Out? (Between Lockout Ambiguity)

(Published on 1. October 2021, 16:33 by tallcat)

Solving "RGB" by Qodec made me want to return to an ambiguity puzzle. Here, given their opposite nature, I thought it would be really neat to use Between and Lockout Lines. Would love to hear your thoughts if you enjoyed the puzzle. Happy solving!

Normal Sudoku rules apply

Lines in the grid represent either Between or Lockout lines. The solver must deduce which are which.

Between: Digits on the line must fall strictly between the two endpoint digits.
Lockout: Endpoints must be at least 4 apart. Digits on the line must fall strictly outside the endpoints.

Digits may repeat on lines if allowed by other rules.



Can be played online at F-puzzles, Sudokulab and CTC

Solution code: Column 5 (top to bottom) followed by Row 2 (left to right). 18 digits, no spaces.

Ridiculously good !
Even after the amazing first part (which is as intricate as it is beautiful), each line still had its own disambiguation logic, until the very end.
Thanks+++
