Caps (Fallout Shelter)

Caps are a resource in Fallout Shelter.

Overview
The basic currency of the wasteland is used as a resource to build and purchase improvements to the vault and its dwellers.

Earning caps
Caps can be acquired from a multitude of sources. Here they are, ordered from worst to best:


 * Low income
 * Leveling up your dwellers: Each level gained by your dwellers will give you a few caps. The amount is determined by the new level: A level 10 dweller will give you 10 caps.
 * Selling gear: You can sell unwanted pieces of equipment recovered from the wasteland. Unless rare or legendary, however, don't count on being paid a lot of cash
 * Rushing: Rushing a room will provide you with cap rewards. The reward is tied to the accident risk, at a 1-1 ratio (the reward increases by 1 cap per 1% of accident risk).


 * High income
 * Exploring: Sending out your Vault dwellers into the wasteland will result in them bringing back outfits, weapons, and, of course, caps. Particularly good explorers will bring back thousands of caps, potentially.
 * Completing objectives: Completing objectives earns some of the highest cap rewards, from as little as 25 to as much as 200 and more.
 * Lunchboxes: Lunchboxes can contain random cards that give you 100, 200, or 500 caps.
 * Discovering the Mysterious Stranger within your vault will reward you with a large amount of caps.


 * Varied income
 * Production: Having Dwellers with high luck in a room and completing a food, water, energy, stimpaks, or RadAway production cycle may on occasion reward bonus caps along with the resources from the room. This can be anywhere from a few dozen to several hundred caps.
 * Destroying already built rooms will return the player anywhere between a few tens and several thousand caps.
 * Bottle and Cappy
