When visiting neighbors' cities, players have the option to assist each neighbor by:
- Reducing a Contract's completion time by 10% of the remaining time.
- Reducing a Building's construction time by 10% of the remaining time.
- Restoring an Expired Contract.
Players are able to assist each neighbor a fixed number of times per day, indicated by the number in the red circle on the lower left of each neighbor's avatar and by the vertical lightning bolt bargraph when viewing a neighbor's city. Players receive 1 Reputation Point each time they assist a neighbor and an additional 1 Reputation Point when they use up their daily maximum number of assists for a neighbor.
Every time a player earns 1 Reputation Point, they also earn according to a formula based on Reputation Level.
A player's Reputation Level will increase at set intervals of Reputation Points (as with XP), see Reputation Chart below. As Reputation Level increases, the player will be able to assist each neighbor more times per day. Players are initially able to assist each friend 5 times per day and gain 1 additional assist at every 5th Reputation Level:

Assistance offers may not expire. Testing has shown that if a player receives an offer of assistance but does not accept it before a contract completes, the offer of assistance is still valid for the next contract started in that production building.
Applying maximum number of assistance offers per day. If a neighbor has fewer active production buildings than the player has available assistance offers, the player can still use up their maximum by applying as many offers as possible, visiting another part of the neighbor's city (e.g. Rocky Mountains), click the available buildings there, then returning to the neighbor's main city. The active production buildings will reset and allow the player to offer assistance again.
