Don't read these unless you want to know exactly how to solve each of the puzzles.
Puzzle 1 is the creation of tools used to obtain food. South and slightly to the east of the food bin (on the beach) is a large fish skeleton. Drop an adult on the skeleton and they will use the bones to make three cutting tools. Once the tools are made they will deposit them in the science lab. You can store up to 6 sharp tools in the lab.
Puzzle 2 is the ability to plug the hole where the water is falling, and instead direct it to the blackberry bush. Drop a villager who is both an adept builder and an adept scientist on the chevron-shaped stone at the base of the cliff. The water will now flow through the pool beside the lab and down towards the blackberry bush.
Puzzle 3 is boiling water, and Puzzle 4 is making soap. You can kill two birds with one stone by boiling water to make soap.
To boil water: you first need to bring water to the kettle in the lab. At the cliff are two sets of bowls, one set at the top of the cliff is for fresh water, one set at the bottom of the cliff is for salt water. Drop an adult on the pile of stones at the bottom of the bridge to the lab, just to the left of the bridge, and they will carry one to the fire. Wait a while and the stone will glow red, indicating that it is ready. Drop an adult on the red hot stone in the fire and they will carry it back to the lab, but only if there is water in the pot.
To make soap: Have a child collect three of the white flowers at the base of the bridge to the lab, to the left of the stones. The child will bring them to the lab and place them on the smaller table. Have an adult get salt water using the lower set of bowls. Once the pot has water, have an adult bring a stone to the fire. Drop an adult on the red hot stone in the fire and they will bring it to the lab. Once the water is boiling, drop an adult on the small lab table where the flowers are. The adult will add the flowers one at a time, and make soap! When the water disappears from the pot, drop an adult on it and they will stack the soap on a nearby rack.
Puzzle 5 creates butterflies. At the bottom of the stream, just below the blackberry bush, is a dry plant. Once you solve Puzzle 2 (the stream), the plant will begin to recover. Several hours after puzzle 2 is solved, the plant will fully recover and turn green. Drop an adult on the plant to cut the leaves. The adult will get covered in sap (you will see green smoke rising from the villager). Once this happens butterflies will appear. Slowly move the villager to the Tree (the big tree), making sure that the butterflies are following. Once you reach the tree, drop the villager on the tree. The villager will wipe the sap on the tree and the butterflies will stay.
Puzzle 6 allows you to rescue frogs. When the frogs are living in the stream underneath the tree, the tree is healthier. Once you solve Puzzle 2 (the stream), wait for it to rain. When it rains, the area around the large palm tree fills with water, and frogs start jumping around. Drop adults in the puddles to catch frogs and move them up to the stream. Rescue at least 6 frogs to complete the puzzle.
Puzzle 7 allows you to build a cooking pit and requires level 2 construction. Drag a villager onto the covered stone pit in the southwest. Once the villager has cleared the pit, it needs to be filled up with four hot rocks. Do this quickly, as if the rocks cool down, you’ll have to start over. Make several people do this task at the same time: when one is walking to the pit with a hot rock, have another ready to put a new rock on the fire. Also, you can start walking to the fire with a new rock when the other one is still heating. It takes about the same amount of time to heat a rock as it takes to walk to the fire, so when you’ve added a rock to the fire, wait a couple of seconds and then get the next villager to pick up a stone from the pile. Make sure another villager takes the hot stone out of the fire before the villager with the cold rock gets there, though! Once you have four hot rocks on the fire, it will tell you that the pit needs to be covered. Drag a villager to the banana tree to the right of the berry bush (image) and they will carry a banana leaf to the fire. This also needs to be done several times.
Puzzle 8 allows you to make cloth. Once you have level 2 Science, the basics of a new hut appear. Drop your villagers on it to build the hut. Once the cloth hut is completed, the "pulpy vines" growing on the rock cliff to the left of the big stairs will be fully grown. Make sure you have a cutting tool from Puzzle 1 in your lab and then drop a villager at the base of the vines. They will go get a cutting tool and cut down three lots of vines to take to the lab. Fill the pot with salt water and put a hot rock under it. Then drop a villager on the table and they will add the vines to the pot. When the "stew" is done, drop a villager on the pot and they will carry a bowl of stewed pulp to the flat rocks on the shore. Keep dropping villagers onto the pulp until the cloth is ready. They will then store the finished cloth by the cloth hut. Each completed process creates three rolls of cloth.
Puzzle 9 is the creation of a Nursery School, so you can educate the children in your village. When you've achieved level 3 Learning, the beginnings of a new building appear. Get your builders to build it. Once it's finished, drag a villager who has mastered at least two skills to the building, and they will start teaching.
Puzzle 10 requires fishing nets, so you must complete Puzzle 12 first. (Seems out of order to me, but there doesn't seem to be a fully logical order to these puzzles!) Once your fishing nets are complete, fast running red crabs will start to appear on the north end of the beach. As soon as you see a crab, hit the spacebar to pause the game. Then go and find two children and drop them on the crab. Then hit the spacebar again to un-pause the game. The children will "distract the crab". While they are distracting the crab, drop an adult on the crab and they will pick it up and carry it to the mossy rocks at the base of the pond. Do this five times to clear each of the rocks.
Puzzle 11 requires availability of all food sources, so again, out of order—you need to complete Puzzles 7 and 12 first. Fill the pot with fresh water and put a hot rock under it to boil it. Get one of each plant (sweet, spicy, and soapy) and add to the pot. Then drop a villager onto the pot to add food from the food bin. This needs to be done twice. Now send a villager to collect berries, one to collect the yellow fruit, and one to collect a fish. It should say that they are "adding to the stew. A child needs to go to find a mushroom and they will add that to the stew too. The whole community is involved! When everything is added, you will get the grand feast. If the stew goes cold while you're still collecting ingredients, simply heat another rock and warm the stew up again. You can continue your recipe. When the grand feast stew is ready, everyone will come get a bowl of it and they will all gather around the fire for their meal.
Puzzle 12 Requires cloth, so you must complete Puzzle 8. When you've created cloth, drag someone to the broken piers on the beach and they will fix them. Keep dragging people on them and they will get cloth from the hut and repair the fishing nets. It takes about six rolls of cloth to repair the fishing nets.
Once you have the fishing nets, your villagers will have another source of food.
Puzzle 13 Requires level 2 dendrology, cloth, soap, and a cutting tool. Drag a villager to the tree and drop them on the sick branch. They will get some cloth to bind the tree. Once the tree is bound, drag someone to the cutting tools and they will cut off the sick branch. Finally, drag them onto the soap and they will clean the cut.
Puzzle 14 requires 20 villagers. Make a stew with fresh water and three sweet smelling flowers. Add some food from the food bin to the stew to finish it. Then drag 20 villagers onto the cooking pot. They will start carrying bowls of yellow colored stew to the Tree of Life.
Puzzle 15 requires level three dendrology and soap. To purify the tree, you need a villager who is both clean of mind and body. Once you've bought the highest level of dendrology, drop a villager near the wind flutes and they will start to meditate. HINT: Since the villager cannot be interrupted during meditation, send someone to teach at the school or to have an adult tell the children a story so they don't interrupt meditation. Adults clearing the river obstruction shouldn't get in the way. Once the villager is done meditating, they will be "clean of mind" and yellow orbs appear around their head. Now they have to become "clean of body" too. Drop a bar of soap in the pond and drop the villager with the yellow orbs in the pool. Wait until they're clean, which you can tell by the white sparkles around them. When you have a villager who is both clean of body and mind, drop them on the hole in the trunk of the Tree of Life. They will go inside the tree, take out some rotting roots and throw them on the fire. Now the tree is purified!
Puzzle 16 requires four steps completed in healing the tree, and three rolls of cloth. When it says "the Tree of Life is recovering" in your tech menu, you will start seeing a purple hummingbird flying around your village. At this point you can drag a villager onto the crates with the moth-eaten braids in the bottom left corner of the lab. They will take one of the braids and take it to a flat rock by the sea. Drop a villager onto the braid, and they will gather a roll of cloth to repair the rope. When you drop a villager on the finished rope, it will tell you that "the lei needs more flowers". Now watch where the hummingbird is goes. The hummingbird will hover around some flowers to pollinate them, after which you can drop a villager on the flower to pick it. If the hummingbird didn't pollinate a flower it will keep telling you "this flower is not in full bloom yet". You can usually get several flowers from one plant. You need six flowers for one lei and three leis to complete the puzzle. Note that if you interrupt your villager as they are carrying the lei to the tree you will have to make the whole lei again from scratch!
Well done, you've now cured the Tree of Life!
