I think you must be talking about freebitco.in as it is the most legit faucet site that gives free coins, has rolling dice and the ability to multiply BTC with its hi-lo game. Yes this site is legit and has been running successfully over the past many years. This site has been mine and many others' first way to earn BTC.
One thing I would like to mention in don't stick around with such sites for too long as many end up with all their coins lost. Too much of playing will make you a loser at the end. Faucets are just a pass time and cannot be treated as a source of income.
