Ren-Bahn #2 [Renban U-Bahn]
(Published on 6. September 2025, 16:46 by Christounet)
Here is the second puzzle I made with this U-Bahn variant. With an extra layer of empty cells. Be aware that the size of the grid is not a square but a 7x8. I hope you enjoy!
The puzzle :
Play on Penpa (answer check with green lines for the U-Bahn and digits in blue).
Rules :
U-Bahn (7×8 grid) : Draw a totally connected loop network through the centers of some cells, which may branch or turn, but may not have any dead ends.
Cells in the spaces above or left of the grid may contain U-Bahn clues as allowed by other rules, where U-Bahn clues indicate how many times the corresponding line shape (i.e. empty, cross, branch, straight line, or turn) appears in the corresponding row or column, irrespective of the line shape's rotation.
Renban lines : each purple line contains a set of consecutive numbers in any order, without repeats.
Example puzzle:
Play on Penpa (answer check with green lines for the U-Bahn and digits in blue).
Solution code: For each row except the last one, the number of lines leading down from than row.
