I'm glad that you like it.

We might have a few problems at the moment, so please if anything is not working as supposed, let us know.

That is one of the UI problems we should fix soon. Technically it is correct that your chance to win the jackpot is 0% if you haven't played at all But it gives bad impression to the users.

Basically, that is the chance to win the weekly jackpot. More you play, higher is the chance to win it. The percentage is calculated as the (number of payments you made / total number of payments) for the week.
There is section in the FAQ (which is in the footer and we should move it to the header) explaining how does it work.

The idea is that 1% of all payments accumulates into the weekly jackpot. We still haven't decided what is the best way to determine the winner. You can check the jackpot list (button in the footer of the page) of all addresses that played with numbers assigned. Your address will be highlighted (if you have played before, i.e. slot that you played in has finished). Maybe we will take the first transaction id, or block chain id in the next week, and take that as a SEED for random.org.

I hope that I have explained our idea.

Those are great news

Thanks

Thank you for your answers.

This is BETA version - we should definitely put that on the website.

At the moment we have one and only slot type and it costs 0.1 DASH. Having that in mind it would be too expensive to send back single instantX to each player at the current rate. We have talked about the sendtomanyix command here:
https://bitcointalk.org/index.php?topic=421615.msg13712922#msg13712922

We hope that it will be implemented at some point.

If we had slots that cost more, then it would make more sense to send InstantX transactions to all players. We are definitely going to add that in the near future, but as I said before, since it is BETA we would have to keep it this way for now.

One more issue is that we are not able to mix coins using dashd, so we can't send a lot of instantX transactions back to the users. Maybe that option exists but I am not aware of it?

InstantX provides nice liquidity for the games when players play - I agree, it is one way, but hopefully that will be improved in the future.

I definitely agree that we should add the option to deposit DASH via mobile wallets using QR Code. I like that idea a lot. We have discussed that already and I believe we will add it in the next version.
