Of course I don't entirely know what's going on, but it's not far fetched to think that this actually just happened. As a matter of fact, if you visit the website you will notice it's completely offline.

But... it worked
Yes, It did, and I used it for a while and had some fun. Of course, the idea that I was getting tokens, getting a share of the casino, kept me coming back, even though I knew I was actually net negative on my playing along. So, you could say I also had my guard down.
Today however, it stopped working, and a good indication that it's Closed for Business is this little fact:

And... It's gone
Just like that, Magic-dice is illiquid. In plain words, they cannot pay out players who would "win" at this very moment. So of course, the website is down, but this did not stop some people from sending funds to @magicdice, funds that are likely not going to be returned.
But Who?
Well, you could say that @magicdice was somewhat anonymous, and this is kind of true. As far as I know the Steemian behind the project was none of the known avatars. But using the magic of the internet, I found a little detail that is very, very interesting.

Yes, our old friend Zombee is actually @magicdice. I would love to say I'm surprised, but I'm not really. Since he is a talented developer, and as you can probably deduce from the other name on that picture, the creator of dmania too.
Why is it a scam?
The word may sound harsh, but as far as I know, If they exit right now, none of us are getting our tokens, and even if we did, even if we received some steem-engine tokens, if the casino has closed it's doors they are literally worthless.
If you are delegating to @magicdice, now might be a good time to get your SP back, granted as far as I know, there's been no communication behind the downtime, nor the cashing out.
