I just checked Rocketpot for the first time, and here's my impression of it.

1. I think it's very important to have the option of cashing out earlier than the target, and it's good that this site has it. It's true that players rarely have the nerve to wait for a payout above 200x, and yet I think they should the ability of cashing out any time they want to.

2. The layout is eye-appealing and the musical score is unobtrusive, just as it should be.

3. I agree with posters above that a small faucet, even just 20 sats per 5 minutes, 10 claims per day, wouldn't hurt (of course, if you know a way of preventing abuse).
