I added information about the faucet as shown in DuckDice's
rules page. The minimum claim is 0.00000078 BTC for the lowest account level, so that's what I added.They also mention that the cooldown period is 3 minutes ~
Actually, it is equivalent to $0.015. The faucet claim amount fluctuates for the price change of Bitcoin, but it remains equivalent to $0.015 in crypto always. And the gap between two faucet claim is indeed 1 minute. I just checked it by claiming faucets on my account. Seems like you have followed the wrong details
The Faucet will be claimed by a player who won a game or in the case of three consequent draws with two different players. If a player lost three times in a row cooldown will be set to 3 minutes.
Simpledice sent me an email saying that they have removed the faucet feature from their site.
I'm also getting the same error message there. Unfortunately, I didn't check their faucet before suggesting about their faucet here. Probably the faucet claim is disabled there as they have confirmed it to you through email.
