You shouldn't be claiming that you have a "faucet" if it is just for purpose of testing the game! Some fun coins would be enough for this.
What is Faucet?
The Faucet feature allows you get some amount of cryptocurrency to play with for FREE. The purpose of the Faucet is to test the game with zero risk prior to depositing.
^ And what if after testing a player will succeed and is able to manage the money from a faucet to become large sums. Is the casino allow the player to withdraw the winning even don't have any single amount that has been deposited? This comment was right, if for testing purposes, why not you will create token or coin just for testing and a faucet not claiming just for testing only because possible it will become a large amount if there is someone who will able to manage it. Nevertheless, your casino looks good and fine with the user interface, just be a competitive gambling casino here that can lure gamblers.
