City Cash

"City Cash makes the world go round - so the Monkeys say. The more of it you get, the faster you can expand your city! You can build another Banana Farm in your city every 5 levels. Build one to maximize your income."

- "More Money!" Quest description



 is the main currency in Bloons Monkey City. It is used to build and upgrade buildings, upgrade your towers in Upgrade Buildings, and researching new bloon types in the Bloon Research Lab, as well as buying decorations in the Mobile version.

At the start of the game, the player has a maximum City Cash deposit capacity of $1500. The main ways of increasing this capacity are by building or upgrading Monkey Banks but finding the Magic Banana Bag Special Item also helps.

City cash can be obtained, up to your city's deposit capacity, by collecting it from your city's Banana Farm/s or from contested territory but it can also be gained (potentially beyond this capacity): by conquering tiles or by winning My Tracks battles; by completing quests; by reaching Contested Territory Milestone or Occupation targets; by raiding other players and by obtaining a 20,000 Bounty Card from a Monkey Knowledge Pack.

If the player exceeds their deposit limit, the City Cash meter will turn red in the mobile version and yellow in the browser version on how much City Cash you have, signaling that it's higher than the maximum capacity. However, any cash coming from Banana Farms or the Contested Territory land will not be accepted while the capacity is full.

Examples of expensive upgrades and items with costs that, when their purchase first becomes possible, exceed the maximum possible bank capacity include the Banana Research Facility upgrade costing $75,000 and the Oversize Airship Support Bay costing $80,000. Both of them become available for purchase while a maximum of 8 Level 3 Banks could potentially have been built in the city to enable a total deposit capacity of $72,000.

Through a use both of city banks and by timely completion of actions that award city cash, players can pay for the buildings and upgrades that their progress may require.
