We examine here the cost / benefits of expanding each type of city building as well as houses.
Common assumptions
- the city expansion or the house upgrade is completed day 25, 10 days from now
- benefit is calculated over next 3 periods until end of game: periods end on days : 105, 150, 180.
- AC number grows such that end of P1: 45, P2, 50, P3, 55 so acf is 27, 31, 35.
- costs and benefits are in donations

3 | +10 | ((160 - 10 x place) / 100) x 2 x Active Citizen Factor |
Benefit over 1 month: = (1.1 - 0.1 x place) x ACF
For 6th place and ACF of 27 = 0.5 x AACF = 0.25 expansion levels =
13.5 donations or 40.5 resources
For 1st place : 0.5 expansion levels

Bath House
You can play a dice game where you have even odds of winning. Choose 3 numbers to have 1 in 2 chance
Level | Culture Points | # of resource donations for city levell expansion |
---|---|---|
1 | 0 | 0 |
2 | +10 | + 0.075 donation to the city per lost game |
3 | +10 | + 0.15 donation to the city per lost game |
You can throw the dice 5 times and you have to guess what the result will be:
- 1 guess: 1 in 6 chance, you win 6 resources (including resource you bet),
- 2 guesses: 1 in 3, you win 3,
- 3 guesses 1 in 2 you win 2.
In the long run you break even but you can easily have a 5-6 resource losing streak
This is interesting. It actually pays more to make 1 guess because you lose 5 in 6 but win 6 when you win. Here you can easily have a 20 resource losing streak and then win 18 resources 5 turns.
I think the only reasonable way to play this is with 3 guesses.
Benefit over 1 month: =
- Betting 3 number: # of players x 30 days x .075 donations x 3 resources x 5 times x 1/2 losses = # of players x 16,875 resources
- Betting 1 number: # of players x 30 days x .075 donations x 3 resources x 5 times x 5/6 losses = # of players x 28.125 resources
For each level of the bathhouse:
With 15 players betting each day 3 numbers 5 times: 253 resources a month.
With 15 players betting each day 1 number 5 times: 421 resources a month.
