Would it be possible in the future to include the rules for each puzzle on the Penpa page? It would be very helpful to be able to double the rules for a given variant without having to open the pdf. Thanks for a great series, and I look forward to next year's events.
I'm not sure if it doesn't show up for you but there is a rules button above each grid that's supposed to show just that. A reminder that Chrome is the suggested browser to use and there could be some sub optimal behaviour on others.
