Acknowledgements and Changes
2023-10-27 Carrick22 kindly sent a nice Ore-dango puzzle!
2023-10-28 A second, harder, puzzle was sent by Carrick22. Aux mark contrast improved (Karoo). Thank you!

2023-10-30 Carrick22 shared a third, larger, Ore-dango!
2023-11-14 Orangetriangle reported a critical bug, now corrected - thank you!
2023-11-23 Random 8 expanded the original rules to include branching skewers, by making two puzzles!
2023-12-14 Partial support for extended skewer crossing, as straight lines, through empty cells, a suggestion by Lennard Sprong (X_Sheep). Please note you must draw the lines first and remove the cells after. Branching cannot occur outside cells (not supported). Puzzle added to demonstrate.
