im pretty new, and Im on primedice and it seems alright so far esp with a faucet.
but I dont know if theres any other ones that are like it.
If you want a bitcoin gambling site that is as trusted as Primedice, then the answer is no.
If you just want provably fair dice sites with a faucet, there are lots of alternatives such as satoshidice, dadice, fortunejack, crypto-games, etc.
