I had a mission to solve all puzzles without buying farming 2 and 3
and my trusty villagers...I got lucky 2 out of the first 7 were runners... and I now have all puzzles all collectables and only 20 population ... sad about the two in the graves though.. they were originals in their 20's when i found them but both elders... I feel now I have achieved something!! now all I have to buy is science L3 and Exploration L3 and get another 41 elders lol

How could you solve puzzle 3 puzzle 7 without level 3 farming??

and the algae eating fish requires level three farming

Oy, I meant Puzzle 7 of course. Going back and editing that.

sorry I solved them all except that one I solved that one last when I had enough tech points

I had all the collectables before I had uncovered the mosaic

Congrats on "all the collectibles". Do you have a strategy? I have only 9's and one 10.

I just kept looking
needed dupicates for tech points needed mushrooms for food...looked and looked, when a rare one came I pause the game grab as many kids as I could find and not only got the collectable but got extra tech points

Ah! I never thought of Pause, so a lot disappeared while I was looking for a child.

the collectables and mushrooms will still disappear on pause mode

but it does keep the squirmy little children from running away

you may want to check the map and look at their normal haunts to see if the kids are there, like down by the woodpile, , trying to get the coconuts, etc

Also I just now realized that after you find and pick up the child, you can use the numerical keypad to zoom him/her to where the collectible is. Assuming you can remember..
