I'm enjoying the maths Advent calendar from @mscroggs A nice puzzle every day https://www.mscroggs.co.uk/
There is also this one published by Technische Universität Berlin: https://www.mathekalender.de/wp/ It has interesting puzzles but some of them require a lot of time to solve!

@alexdbolton@mathstodon.xyz @mscroggs@mathstodon.xyz Thanks for the info. Both sites look fun! But I could not complete the registration process on Technische Universität Berlin's puzzle site. Are there anyone in similar situation?
