Happiness (Fallout Shelter) (2024)

in:Clarification needed, Fallout Shelter gameplay

English

	The following is based on information from Fallout Shelter or Fallout Shelter Online.

Maintaining happiness[]

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.
A successful rush raises happiness for everyone assigned to that room by 10%, but failing one does the exact opposite.
Since the radio studio boosts Happiness in the Vault, placing high Charisma dwellers inside the radio room will increase everyone's happiness greatly.
Give them some time with the opposite sex in the living rooms. It will lift their spirits and make them happy. If they are in any other room, their happiness will raise to at least 75%.
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.

Happiness icons are color coded, for easy reference:

"Green: Your dweller is happy, way to go!"
"Yellow: Your dweller is doing okay, but could be happier."
"Red: Your dweller is sad, cheer them up."

Effects on gameplay[]

Dwellers' faces will reflect their happiness level. The happier dwellers are, the harder they work. The collective happiness of the vault will give a happiness bonus, giving an extra percentage on resource creation. The bonus ranges from 0% increase to 10% increase and is calculated with the following formula:

A dweller with 50% happiness

Good happiness animations

Low happiness animations

Notes[]

Dwellers will often vocalize what they want, so pay close attention to what a dweller is telling you to know more about what makes them happy.^{[clarification needed]}
Dwellers can have 1/3 irradiated health pool and 1/10 missing HP, but still have 100% happiness, as of version 1.13.13.^[1]
