The best way to play the game is to check your puzzle.See how many of the puzzles are done.Your builders are needed to uncover most of the puzzles.Make sure you keep your food supply up with farmers.You can have only 10 farmers out of 90 and if they are young enough they will continue the food supply until they are old.Make sure as they get older and more babies are born to divide the work load out evenly.Doctors are needed to make sure your villagers stay healthy.Builders uncover puzzles and also help to make the population by building homes.You need all the scientist you can get so you can get your tech points up so you can buy the skills.Farmers are needed to keep them fed and alive. Once you have the golden child,he'll make sure the food supply stays in control.When your not playing the villagers are still living,so keep them fed and healthy and keep them working.My older people I usually let them get tech points or let them populate.They seem to live longer that way.The most villagers I have ever gotten is 91.And I have had about 7 sets of triplets.I enjoy my villagers.You will too.
