The Extractor is a building used to extract shapes or colors from source tiles. It is unlocked from the start of the game.
Extractors have a thinner white border. They can only directly output onto a belt, so their outputs have to be merged using balancers, and it is impossible to utilize the entirety of a resource patch.
The Chain Extractor is a variant of the Extractor, used to extract shapes or colors from source tiles, with the upgrade that it can be chained so that one extractor feeds into the next. It is unlocked after Level 11.
Chain extractors have a thicker dark border. Because chain extractors can feed into adjacent chain extractors, they are much more space-efficient, and the entirety of a resource patch can be utilized.
Their base speed is 0.4 items/s (24 items/min), exactly 1/5 of the belt base speed. This means that if they are on the same upgrade tier, 5 extractors will exactly fill a belt.
Extractors will only produce output when placed on a shape or color resource tile. If placed on a blank tile, they will do nothing.
