Thanks for the visitors today - and your feedback.
One aspect keeps coming up though:
Should play be on-chain or off-chain?
For on-chain play, there's no need to register, verify, load up an "account". All transactions/plays are viewable on the blockchain. But there's more of a hit due to fees. We actually contribute 0.0001BTC towards fees when sending winnings. Is that enough to make it worthwhile to players? Players having accounts adds to the security workload of a website. We'd also rather not hang onto players' funds any longer than necessary. Both of these aspects make a website more of a target for hackers.
We were originally on-chain, then we changed to off-chain but then people complained about having to sign up!
Is the answer to implement both? Or do players prefer on-chain for more peace of mind? Or maybe it's a case of "you can't please 100% of the people 100% of the time"?

How to verify results ? Are the game results probably fair? I don't see any thing regarding fairness of the results, no secret key or seed nothing to verify results.
Also what is the house edge?

Provability / fairness: If you click on the question mark icon ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fbitcoin-arcade.com%2Fimages%2Finfo.png&t=665&c=pvkS1ObM0EotAw) then click on the microscope icon ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fbitcoin-arcade.com%2Fimages%2Ffairness.png&t=665&c=U71dV7KxPhkdZg) then you should see a list of hashes of future seeds plus the results of previous races/grabs. We publish the hashes of future seeds in advance so you can check they don't change when people play. There used to be a detailed walk-through of using the seed, etc. but we removed it as it took up too much room. Essentially there's a SHA256 hash of the seed and a fixed string to provide an integer that maps to a winner.

Your site is giving me a certificate error. You may want to fix that. It says that my connection is not secure. I am currently using mobile. I did not proceed. Hope you can fix that soon because I like the idea of this game of yours. Wish you could give some free bits to try out and see how the game works for starters.

The website has a brand-new SSL cert as of 26th November 2016 which checks out fine on Chrome but I see the same issue on my Android. (I have to admit I don't browse websites on my phone) I'll get onto this ASAP!

How much confirmation does it require to send back wining? Is it only 1 or 2 We publish the hashes of future seeds in advance so you can check they don't change when people play.
How to check game id? there is no any info regarding game id in the game history also it seems that probably fair page isn't updating in real time.

Your site is giving me a certificate error. OK, that error has gone away on my mobile now - can you check with yours please? It turned out to be a missing "intermediate" certificate that linked the website's certificate with the root CA's certificate. I guess Chrome has secret sauce to somehow cache/know/find/download that certificate where my mobile did not (although Android is made by Google too so work that one out!)

Visited the site, looks interesting with flat graphic design catching eyes, I like it. Like people said the provably fair should be place to page tab which presenting the provably fair description. The notify about the result game is should be adding, if I play multiple game and the amount is just a random btc, I don't know where it's come from, probably adding a transaction information for every bet is good idea, for example I bet on toy game, so I get a game ID, when the result come out it's also show a game ID which I have been take a bet.
And one question, how if the network become slow? When I try to send an amount to deposit for a bet, but the network become slow and the game has been running. I see horse games running fast game.

Seriously? A 10.32% house edge for your 2x multiplier game? ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FZVTH54u.png&t=665&c=mUvSozDW1btwOQ) Do you actually expect people to bet and be expected to lose 10% of their wager, every time. Bitsler (and most dice sites) offer less than or equal to a 1% house edge, and you guys are 10 times that. Just crazy. Even those non provably fair slot games have a lower edge. 8.359% edge for your arcade game, slightly better but still crap. -0.5*(3665/10000)+-0.3*(2618/10000)+0.1*(1666/10000)+0.2*(1527/10000)+2.5*(524/10000)

We asked for your feedback and made some changes: It's now easier to check and verify the fairness of the games that you play. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fbitcoin-arcade.com%2Fimages%2Fbet-history.png&t=665&c=1egq2bwwP1mqAA) You can click on the game ID which will take you to the fairness entry for that game. You said our house edge was too high - we were originally matching the odds from the real seaside games. It's now down from around 10% to around 1.5%. You're now more likely to win, and we have payouts up to x25 your stake, so come along and join the fun! ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

I really like your arcade.
In my opinion a lot of casinos are too overloaded with features; I'd rather have retro games like this than fancy slot games that aren't provably fair. And good on you for lowering the house edge for a fairer size.

2 Questions,
It says
For every game, a random secret string is generated and we publish the SHA256 hash for this ahead of time.
Where is this secret SHA256 hash posted exactly? I can't find it.
For the horse game, what is the house edge exactly. Is it the White hour which is 3.94%? So does that mean the house edge is 4% for that game?
