Happiness (Fallout Shelter)

Happiness is an important factor in keeping a vault functioning a peak efficiency in Fallout Shelter. The higher a dweller's happiness; the higher the dweller's efficiency bonus is. There are several ways of keeping vault dwellers happy:


 * Keep them healthy. A lack of food, water or power will bring down their mood.
 * Assign them to the correct job. Dwellers are happier in rooms which correspond to their highest SPECIAL stat.
 * Give them some time with the opposite sex in a living quarter. It will lift their spirits and make them happy.
 * If they are sick, a little RadAway and/or Stimpaks will increase their happiness.
 * Sometimes they just get bored. Assign them to the training rooms for some book worm or physical training.
