Happiness is a game mechanic that determines among other things the speed of your citizens at their jobs.
The higher the happiness is, the faster your workers work. Happiness goes from 0-99, then :D and XD. The working rate at happiness 0 is 0.25x (between 0-99 seems to be linear), :D is 2.00x (100), and XD is 2.50x (125).
- Getting the happiness to 53 is one of the tasks in the scenario A New Beginning.
- Getting the happiness to 80 is one of the tasks in scenario An Interworld City.
- Getting to :D happiness for the first time gives you the Statue of Happiness building.
- Maintaining :D or higher happiness for 14 in-game days gives you the Beacon.
Happiness is achieved by satisfying your citizens goals. To see which areas could use improvement, you can click the happiness counter for more information.
Can be achieved by constructing higher happiness homes for people to live in, upgrading homes You can make use of the Living Research Center to quickly upgrade basic homes into other kinds.
Make sure everyone has a job/school to go to. Some jobs can help with other aspects of happiness i.e. pubs.
Build more Nightclubs. Scrapyard Nightclubs are better for providing this happiness than normal ones.
Simply build more Pubs & Restaurants. Factory Pubs aren't any better than regular ones, though. The Xmas Market counts for this.
Build more Modern Art Museums. Art Colonies can help too.
Place more Parks, Botanical Gardens, Eco Farms & Xmas Trees.
Build Arcades, Lab Escape Rooms & Holo Game Halls.
Make Schools, Tinkerers' Houses & Libraries. Build enough schools to accommodate all child citizens. Make sure a citizen is actually working in the school building or it will have no effect.
Place Medical Clinics & upgrade them. Increasing the Education happiness helps in one of the upgrades.
- The only way to get happiness above :D is to use the Festival HQ.
