3rd Annual Puzzle Lovers Advent in Advance (October 2021) (and a bit of November)

not sure if this is allowed here or not, haven't found anything related to 'events' in the faq, so let me know if I have to delete it or something.

anyway, I've just started this year's advent in advance, which is a month-long giveaway event in october with a simple concept: 31 days, 31 games. each giveaway runs for 3 days, ones started on odd days (1, 3, 5...) are for everybody who's lvl1 or above, even days (2, 4, 6...) are only for group members.

I won't link the group in case it's a no-no, just the first giveaway with further details, started earlier today. tomorrow I'll link day 2 to it and link day 2 to day 1, and so on. I think this is what's called a train around here.

ok, so here's day 1, good luck:
