Draw a connected subway line plan in the grid, which runs horizontally and vertically from field center to field center and does not leave the diagram anywhere. The lines can branch or turn at the center of the field, but there are no dead ends. The numbers at the top and left borders indicate how many of the corresponding shapes appear in the corresponding row or column. The shapes can also be rotated.

Solution code: For each column except the last, from left to right, the number of lines leading to the right. Then for each line except the last from top to bottom, the number of lines going down.

Great puzzle! Nice end to the series.
Really enjoyed these - it's cool seeing a series focusing on some of the more theoretical deductions in u-bahn like this, made somewhat approachable by the small grids. I knew most of the logic in these before starting, but this seems like it would have been a great series to learn from if I hadn't.
Thanks for the puzzles.

Ja, da ist uns wohl tatsächlich dasselbe aufgefallen. Diese Art Einstieg hatte ich jetzt erwartet. Wirklich sehr schöne Serie :)
