It works just by entering your Bitcoin address and get free Satoshi every certain time based on the faucet itself, sometimes there is a range of payment not fixed payment,
You can also use some sort of Bitcoin faucet rotators,it contains several Bitcoin faucets at the same page and you use your bitcoin address to claim from the first faucet then move to the next faucet in the same page till you claim your free bitcoins from all faucets,of course this is much easier and more convenient.
this is a good example of this rotators
