Acknowledgements and Changes **2023-12-12** Added a more complex divisibility check to let setters immediately know certain puzzle-parameter combinations are unsolvable. **2023-12-13** Fixed a regression in the knob interface noticed by @PinkHoodie - parameters can now be edited normally again **2023-12-16** Territories are now colorised and a recent regression found by @placeholder was fixed. **2024-08-07** A regression on the divisibility checker found by @PinkHoodie was corrected (cause:template changes) **2024-08-07** @PinkHoodie transcribed a missing puzzle from the holiday series (2011) - thank you!
