Puzzles are ordered going across the rows from left to right, starting at the top left hand corner.

by the way, if you're hoping something neat will happen when you finish the puzzles, like a thing telling you that you won, forget it. nothing special happens.

Puzzle 1: the well - put a villager to work on the construction in the middle of the village, then when they have a little experiance, take them to the well. they will fix it.

Puzzle 2: the hut - have one or more villagers work on the construction in the middle of the village until it is done. you can check thier progress by clicking on the construction.

Puzzle 3: the ocean - drag a villager to the debris on the beach. they will start cleaning it up. it takes a very long time, and there is no way to check the progress.

Puzzle 4: the school - take a master scientist to the long hut, they will convert it into a school. you get a master scientist by having a villager research for a while.

Puzzle 5: the lagoon - You must upgrade to contruction level 2 before completeing this puzzle. once you have, take a villager to the pile of rocks in the top right hand corner of the island. have them clear it until it is gone, which will take a while.

Puzzle 6: the fish - you must complete puzzle 5 for this. once you upgrade to harvesting level three, Take a master farmer to the lagoon, and they will begin hunting a strange fish. It may take many tries before they succeed, so be patient and keep trying.

Puzzle 7: the graveyard - you must upgrade to spirituality level 2 first. once a villager dies (hopefully from old age) drag a villager to the upper right hand corner of the island. they'll do the rest.

Puzzle 8: the plants - there are many strange plants surrounding the edges of the island. drag villagers to all the plants and let them study them. it doesn't have to be the same villager for it to work. (Plant locations: three on wall between boulder and lagoon, one just below the lagoon, and two odd looking flowers on the right hand side of the island)

Puzzle 9: the flowers - you must complete puzzle 5 for this. on the right side of the island, below the graveyard, your villagers will see dead flowers. let them water the flowers with the lagoon water... eventually they will grow.

Puzzle 10: the star flower - you must complete puzzle 13 and 14 for this. once you have butterflies following your golden child (this will make sense if you read the other puzzles) take him to the middle plant along the wall between the boulder (or cave, if you've finished that puzzle) and the lagoon.

Puzzle 11: the temple - you must upgrade to construction level 3 for this. you may also have to have spirituality level 2, but i'm unsure if that was a requirement.
once you do, drag a builder to the rocks at the bottom right corner of the island. it will take a while, as all construction does.

Puzzle 12: the idol - you must complete puzzle 11 for this. you must also upgrade to spirituality level 3. afterward, drag a builder to the rock that everyone's been so curious about, located below the lagoon. again, it takes a while.

Puzzle 13: the golden child - you must complete puzzles 5 and 12 for this. you must also upgrade to fertility level 3. take a nursing mother to the lagoon. the golden child will appear and will remain 5 years old, no matter how long you wait. he can do the puzzles that require him imediately.

Puzzle 14: the butterfly - you must complete puzzles 9 and 13 for this. take the golden child to the flower garden. it may not work the first time, so just keep moving him around. the butterflies also may have to be on the map, but i'm not sure.

Puzzle 15: the treasure - you must upgrade to construction level 3 and technology level 3 for this. take a master builder to the area below the food bin and drop him around until he digs. it takes a few tries, but eventually other builders will help. it takes a while.

Puzzle 16: the cave - you must complete puzzle 13 for this. luckily, that's all you have to do. the golden child does the rest on his own.
