Tazra B: How do I finish puzzle 16 on Virtual Villagers 3: The Secret City?
I have opened the door that leads to the secret sun dial room, and I have placed my villager onto the ghosts. I have revealed the secret of Isola but when I click puzzles it says that Puzzle 16 has not yet been completed. Any one else had this problem?

Puzzle 16 – The Sun Dial

You will need to have solved Puzzles 13, 14, and 15. Once all three keys are in the door, the

sun dial room will be revealed. Drop a villager on the sun dial until it reaches the position at

the furthest left (there are three locations for the sun dial). When a beam of sunlight hits the

sun dial, ghostly figures will appear in the room. Drop a villager on those ghosts and the

mystery of the secret city will be revealed! Note: I had to do this a couple times before the

game gave me credit for completing the puzzle… not sure why… but be prepared to do this

action (and watch the movie) more than once. – Lara
