Fallout Shelter rooms

There are a total of 20 available rooms that begin at level 1 and can be upgraded with caps to as maximum of level 3. Rooms can also be merged by placing an identical room of the same tier next to it. Each production room requires a specific S.P.E.C.I.A.L trait to run at its max efficiency, and each training room increases the traits of dwellers.

Production Rooms
Production rooms yield one resource, except for the Nuka-Cola bottler which produces Food and Water. Production time is dependent on the number of dwellers and their trait level for the room's required trait. Once a room has produced a load, they do not produce any more until you actively collect the resource. Depending on the Luck of the workers, collecting the resource may also give a sum of caps.

These rooms can be rushed depending on the probability given in-game. This probability depends on the luck and required trait of the workers in the room, and if successful the room will instantly yield resources and a number of caps equal to the percentage of the chance taken. A failure results in an instant incident in that room, either fire or radroaches.

Although it is not visible in their SPECIAL stat bars, wearing outfits that raise stats will raise them beyond 10, helping production.

Training Rooms
These rooms raise one of the traits for the dwellers stationed in it. Training time depends on current level and how many occupants are in the room. Going from level 1 to level 2 takes a few minutes while going from 9 to 10 takes up to 20 hours. Dwellers train faster with more dwellers in the room.
