I play my game on normal with X2 speed.
Puzzle 1 requires a builder to uncover the well which will supply water to you villagers.
If you use the help feature, this puzzle is accomplished during the tutorial. Simply find
your builder by clicking the villagers and looking at their occupation to find the
builder. Pick up the builder and drag him/her to the well. They will uncover it
immediately.
Puzzle 2 is the completion of the hut which has some building done on it already. After
your builder uncovers the well, drag him to the partially constructed hut, and he will
complete it.
Puzzle 3 is the completion of cleaning up the shipwrecked debris on the beach. Your
farmers will not be able to fish with debris on the beach. They cannot access the water
until the debris is moved. Level 3 of Farming is required for fishing.
Puzzle 4 is the founding of the school. Drag and drop a master scientist to the east end
(side near the food bin) of the building opposite the research table.  The action will
read: Founding a school.
Puzzle 5 is the clearing of the blockage of the lagoon. You must have level 2 of
Construction to complete this puzzle. Drag a master builder to the pile of rocks blocking
the lagoon and they will begin to clear the rocks. This puzzle is very important. It must
be completed for 2 other puzzles to be completed.
Puzzle 6 can only be completed providing you have completed puzzle 5, and you must have
level 3 in Farming. Drag and drop a master farmer into the lagoon. He will begin to search
for a strange fish. If he emerges without the fish, throw him back in. It will take
several tries, so patience. And keep putting him back in the lagoon until he emerges with
the fish. He will take it to the food bin, and the celebration begins!
Puzzle 7 is the discovery of the graveyard. You need 2 things to complete this puzzle.
You must have level 2 of Spirituality and a dead villager! Drag and drop an adult villager
into the barren cracked dirt area in the upper right hand corner of the village. The
graveyard is discovered and flowers will bloom. The villagers will celebrate and then
begin burying the deceased. After the first time, they will continue this procession each
time villagers die. All adults stop what they are doing and take part.
Puzzle 8 is the completion/discovery of herb mastery. There are 4 plants that one villager
only will have to study. This gives the knowledge to the entire village and only needs to
be completed once. Each of these plants are medicinal herbs. Two are located on the east
side of the village...one is a rose, the other a purple lily. One is located in the back
of the village near the boulder. It is a medicinal cactus. The fourth is located just
south of the lagoon. Keep your villager highlighted so you can see when it say's, "Now
your whole village understand the meaning of this herb."
Puzzle 9 is also dependent upon the completion of the lagoon. On the east side of the
village there is the strange green patch/field where the little ones go when "Nature is
calling. Drag a master farmer to the patch. He will begin to water it with water from the
lagoon, NOT the well. This patch is watered with water from the lagoon only. Other
villagers of different occupations may be dropped in the patch also, some will stick with
the watering, some will not...just drag them right back to the patch and they will water.
It is a sight to see the procession of villagers with their bowls of water.
It takes an enormous amount of water for the flowers to return.
Puzzle 10 is a strange one as you cannot complete it until you complete Puzzle 14.
Puzzle 10 is the return of the fruit to the fruit bearing orange plant in the back left of
the village just near the lagoon. In order to complete this Puzzle, you need the Golden
Child (Puzzle 13) and the butterflies he summons (Puzzle 14) in the flower garden to
pollinate this fruitless, fruit bearing plant.
Puzzle 11 is restoring the temple from the ruins found in the lower left of your village.
Drag and drop some Master Builders over there; make sure you have Level 3 of

Puzzle 12 is completion of the idol. This is chiseled out of that huge rock that the
villagers are so curious about.  In order to carve/chisel the Idol, they villagers must
have completed the restoration of the temple, and have Level 3 in Spirituality. Drag and
drop your builders to the rock and they will begin chiseling.
Puzzle 13 is the birth of the Golden Child.  Before his birth, you must have completed the
idol, the lagoon, and you mush have Level 3 in Fertility!  When these thing are completed,
take a nursing mom to the lagoon and drop her in the water.  The baby immediately becomes
the golden child and walks on water all adorned in gold. There is a great celebration.
Puzzle 14 is dependent on the completion of the flower garden, and the birth of the golden
child.  Drag him and drop him in the flowers and he summons butterflies.  When you see the
butterflies, move the golden child back to the orange fruitless plant back near the back
of the lagoon. (Puzzle 10) The butterflies fly around the plant pollinating it, and the
fruit returns.
Puzzle 15 is the buried treasure. Only a master builder can locate it. Grab a builder and
slowly move him around that area until it says he sees something, or "Can something be
buried here" Then drop him. May take several tries. Other villagers will join in. Your
village must also have Level 3 in Construction and Science. The buried treasure can be
found south of the food bin in the sandy area. It is located in line with the temple and
food bin.
