All the free Bitcoin sites given by the others look already awesome!
Just to add some more value to it right here, I'd like to suggest to look at the type of instant pay-out Bitcoin/other crypto coin faucets which could be helpful for you to collect coins right in your wallet, faster than other direct payout faucet sites. (which usually has a minimal threshold to withdraw)
Just to give a clue, only if you aren't aware yet, crypto faucets connected with Coinpot Micro Crypto Payment wallet or Faucethub wallet are instant payout that you can get the earned coins in your wallet as soon as you claim. (Faucethub has got some deceitful part in it though, just briefly speaking)
Several or slightly more of free faucets coins are belonging to Coinpot wallet, and they offers in some different crypto coins respectively, like Bitcoin, of course, Dash, Litecoin, Doge coin. I especially like it because all coins I earned from each separated site of Coinpot faucets are paid and stored just in one account and it's an easy management for the whole different types of coins, plus it allows to exchange each different currency to what you want to exchange to within the coinpot wallet dashboard. So it's quite convenient managing coins. (I usually earn all of each different coins and store them in the account for a while, and when I want to transfer all them to other crypto wallet, I usually exchange all them to one single currency for a convenience like some litecoin,bitcoin,dash,doge, all them into either Dash or Litecoin.
