Nice looking roulette table. I prefer these types to the other more graphic ones. It's nice and simple. Provably fair looks pretty good, I'm a little confused how your using a 3rd party RNG during the process (I think, correct me I'm wrong and I'll edit this).

Best of luck!

I don't see where it says they're using a 3rd party RNG, but they will need to source their randomness from somewhere.  Where they get their random numbers isn't really our concern.  In fact if their random numbers aren't very random then that's good for the players since we can take advantage of patterns in the numbers if we spot them.

What I'm not seeing is where the private key is published after each spin.  I see the public key and the hash of the private key, but the private key itself isn't showing itself to me.  Maybe I need to sign up first?  Or look on a different page?

The most obvious thing you're missing is the ability to bet on groups of 2, 3, 4 and 6 numbers by placing bets on corners and edges.

Thanks for the feedback. Both keys used to generate the seed are generated on our server, but they are pushed to the user before they can place their bet for the next round. Haven't received feedback regarding that yet, but I can see how a lack of a third-party rng could potentially dissuade some users, despite the provable integrity of the seed- what do you think?

The private keys are published on https://bitspin.co/spins. I'll add a link at the bottom of the page.

I'll consider adding group inside bets. I was resisting it at first in favor of simplicity. Thanks for the input!

That's just an algorithm that generates random-looking numbers given a seed.  The seed comes from the hash of the private and public keys.  And those two keys are generated using some undisclosed random number generator.  But it's all good.  Smiley

Does anyone have any thoughts as to how game play could be improved? Specifically:

-Is it clear that you have as much time as you need to place a bet? (I can see how the countdown timer might lead one to believe that you need to place and submit a bet before it expires.)
-Is it clear that you can immediately play for "fake bitcoins" when you land on the site?
-Is it clear that you have to click "Place bet" for the bet to be submitted?
-How do you feel about the interval length between spins (currently about 30 seconds)?

Thanks for your feedback and for signing up if you've already done so!

Thanks to everyone who's been playing, and congrats to the winners!

A mini tutorial was added after we got feedback that the play mechanics were somewhat unclear. Also, play is smoother on mobile platforms now.

Feedback is most welcome!

Thanks for the feedback! I agree the spin history should be on the side- I'm currently experimenting with different ways of doing it.

By the way, if you hover over the history numbers, you'll see the bet you made on that spin (if you made one), and you can click that number to repeat that bet. I'll make that more clear too.
