Pentominous U-Bahn (Warm-up #2)
(Published on 15. November 2024, 09:15 by KNT)
Draw a totally connected loop network through the centers of some cells, which may branch or turn, but may not have any dead ends. A clue outside the grid indicates how many times the corresponding line shape (i.e. a cross, branch, straight line, or turn) appears in the corresponding row or column, irrespective of the line shape's rotation. The loop network may enter the black cells freely.
Every pentomino must contain one turn, one straight, one branch, one cross, and one empty cell.

I found this much more accessible/ intuitive than the first warmup, but perhaps I was rusty! What a fun ruleset, so inventive. I thoroughly enjoyed this. Onto the main course now, wish me luck. Thank you for two great warmup puzzles!

Really fun ruleset. Each pentomino needing one of each shape was more intuitive to me than each pentomino being composed of only one shape (as in #1). However, the blackened cells in this puzzle kept tripping me up. I hadn't appreciated that a Ubahn clue could be satisfied by the shape of a blackened cell, and the dark color made it difficult to notate/keep track of.

Even more fun than #2! Great way to lull us into a false sense of security :D
