I鈥檝e enjoyed this advent calendar so far. I鈥檓 on day 14. The puzzles have a mix of easy to difficult and do require creative and logical thinking.
I gave this 3 stars because of the following:
There are some mistakes in some of the puzzles that you only find out after giving up and looking up the hints on the website.
There was a puzzle that was so hard that I used all the hints, but then the answer wasn鈥檛 explained at all. So I鈥檓 left without closure or understanding why.
Also, there was a puzzle that required calling international numbers. Knowing that it鈥檚 not included in my phone plan, I was forced to use the hints to move on. This is a huge oversight on the game makers鈥 part.
If none of those things bother you, then I say this is a great alternative to candy advent calendars.
