KPK 2021 Leftover: Double Back (Little Killer)
(Published on 29. September 2021, 07:00 by athin)
Rules of Double Back:
- Draw a non-intersecting loop through the centers of all empty cells.
- The loop passes through each region exactly twice.
These two puzzles are the leftover of KPK 2021.
The first one is a standard Double Back puzzle. The second one is a variant with Little-Killer clues: Digits on the pointed diagonal show how many cells the loop bends on the corresponding diagonal.
Solution code: Row 5 for the first puzzle and Row 2 for the second puzzle (left-right). Use L for cells with a bend in the loop, and I for cells with a straight in the loop.

Nice, but very tricky.
