What determines the We Love the King Day? How much happiness exactly do you need?

Also, is there any benefit to having a huge amount of health, like a pop boom?

It's somewhere in the game manual booklet... (ya.. it's thicker than CD case... )

- being happy, and being healthy. then u got a chance.

- benefits is u don't have to pay them to work, no maintainence cost.

Default settings require a city size 8 with no sickness and no anger above the capacity then you have a 1 in 1000 chance of it happening the bonus is for the city you pay no maintinance for that city that turn it happens.
