Well I've completed every puzzle except one...#15. The hints on this website said that you had to drop your villager in the EXACT spot to complete this puzzle...Where is it? I'm pretty sure that thing is a trasure chest.

Thanks!

It's more than a matter of the right spot. You have to have a villager with the right skills and the right tech levels.

If you were looking in the spoilers section of the guide, the exact spot was described for you. You can also see screen shots if you scroll through the 'share your pics' thread.

i know where the spot is!
it is in the middle of the temple,food bin.sea and a house
and u need a master builder and u need to have research
all tech

The above answer contains incorrect information. There are tech requirements, but not that many.

well thats all i know since i just found that out what the 15 puzzle is and where and i had already mastered all tech
so i did not know what and how much u needed of tech to do it

Usually we try not to post blatant spoilers, since all of the solutions are posted in the Virtual Villagers Guide. Most of us just post the link to that guide, since the answers are already there, and it doesn't spoil the game for people who didn't want to accidentally see the answers. It's better to make sure that you really know an answer before you post something, since people depend on what's in the forums.
