There is a difference. The other casinos only allow you to claim their faucet when your balance is 0 so you can try out the games for free. Then when you have a balance the faucet is unavailable. We allow you to use us just as a faucet and not use the rest of the site if you want. That's why even though the site has changed from when it was just a faucet funded by advertising having the word free in the name is still appropriate.
Therefore, Freebitco is the best and most generous faucet which is a casino as well. We can also say that Freebitco is a casino which has the best faucet.
Generally, users can use freebitco as a casino and also a faucet. These two are not in conflict with each other.
