This website is straightforward and easy to use. It demonstrates the speed of the Nano Network through faucet claims. There are no additional earning options available - only the faucet. To participate, simply connect your wallet by entering your Nano, XDG, or BAN address and spin every 20 minutes. There isn't a visible countdown, so you'll only find out how long you need to wait after attempting to roll again.
Sometimes, the site may 'forget' your wallet, but you can easily fix this by re-entering it and you'll be ready to go again!
