RS-Bahn (2) (Region Sums U-Bahn)
(Published on 6. December 2025, 00:00 by cyddrdrd)
Rules
- Sudoku: Fill the grid with digits 1-6, so that no digit repeats in the same row, column, or 2×3 box.
- U-Bahn: Draw a totally connected network through the centers of some cells in the grid. The network may branch or turn, but may not have any dead ends. Clues outside the grid indicate how many times the corresponding line shape (cross, branch, straight line, or turn) appears in that row/column, regardless of rotation.
- Region Sum Lines: Box borders divide the network into segments with the same sum.
