City project

The city project lets players donate unused items to benefit their city. It is a permanent feature on every world, unlocked automatically at 1,000 prestige.

Contributing

• Click your city and open the City project tab: next reward, project points still needed, contribution ranking.
• Exchange rate shows how many project points each item is worth; the cost per point depends on the era.
• Pick the item and the quantity, then Donate. You cannot give more than the current reward still needs; any surplus carries over to the next one. Only gold donations ask for confirmation.

Rewards

• Up to five rewards per city level, unlocked in order. Once all five are unlocked, the city must level up. If it levels up before, the remaining rewards are lost.
• Each reward needs 50% more points than the previous one (50, 75, 113…); the total also depends on the city's level and population.
• Some rewards benefit every connected player (revenue bonus, shorter waiting times, prestige bonus, better competition rewards); others are vouchers for players whose home city it is.
• One of the five steps of each level hides the Magnus bonus engine, given at random to a contributor.
• The best contributors earn prestige.

Good to know

• It is switched off 24 hours before the endgame.
• You cannot contribute while co-managing another account.
• It works in the mobile app.
