I've been playing for a few days now and have been following the posts of this forum and have noticed quite a few describing PUZZLES they've solved and doing so by the puzzle's number, yet I've not seen any list of Puzzles? Am I missing something? Can someone plz point me to a reference for these puzzles? Not really looking for a spoiler, just a list or hint as to what the puzzles are. From what I've read, there seems to be Twelve puzzles.

TIA, and sorry for the newbie question.

If you select "Menu" and then "Puzzles" you'll see the screen that displays the puzzles. Most of them will have question marks, because they aren't yet completed. People refer to them by number, according to their position on the screen, so as not to reveal too much information about them.

on your main page where you can change "new game" and prefrences.... you can click on puzzles. You are right, there are 12, and as the villagers "discover" something new, or complete a task a puzzle will be solved.
Hope this helps.

Hanging my head in shame....I guess I should explore the menu a bit more ehh?

As it turns out I've completed 1-4 & 7. Thanks!!!

Also, on the puzzles screen there is a button to access your game stats!

lots to explore, both in the game itself, and how you can play it. I have been playing with it for quite a while now, but still learning new things everyday
