Thanks, Matthew for all of your hard work to create the Advent Calendar. It was so much fun to work together with my son, even though we live thousands of miles apart. He is a coder and I am definitely old-school math.

×2 ×1 I have really enjoyed these puzzles over the last 26 days. I particularly liked the variety of puzzles, some leading me to graphing software, others to my amateur coding, and many just to a piece of paper and a pencil. Some ideas for the classroom too!×2 ×1

×2 ×1 @(anonymous): Yes, you should have enough info to work all that out. I recommend using a spreadsheet to keep track of all the feedings. ×1

×1 Really struggling with the final logic puzzle this year...is it possible to work out what each reindeer was fed before each test flight as well as their favourite foods? The information seems so little!

Huh! Today's clue gave enough info to bring the possibilities down to bruteforceable levels... and the second attempt worked!

I just realised that the advent calendar itself is a magic square, nice touch.×2 ×1 ×1

×2 ×1 ×1 @Elijah: Each reindeer was fed exactly one food before each test flight. Multiple reindeer may have the same favourite foods. ×1
Matthew
×1 Can it be assumed that before each reindeer has a different favourite food, and/or that the saboteur fed each reindeer a unique food each test flight? ×1

Each puzzle was tricky enough to require some thought, but not so tricky as to be discouraging.
Looking forward to next year already!
