>> Retro-style horse-racing arcade game! >>

[catbref]

We were tired of playing the same old BitCoin games, so we decided to come up with something fun and new. We just loved visiting the arcades and spending our pennies on all the wonderful arcade games, eating ice cream and having fun so we decided to bring a bit of that magic to you.

Play this vintage-style derby racing game using BitCoin or BurstCoin. Play for fun with small amounts,  0.002 to 0.02 BTC or 2,000 to 20,000 BURST, but WIN BIG with our top X 25 multiplier!
We're a new company and we'd just love your feedback on this new game, or tell us what future games you want to play!

the site is really nice, but not have the provably fair? Is the first thing i see in new gambling site. Later, you can add a faucet or a fun games mode for simply test a site

[panjul07]

From the picture in the OP, it looks good. But when I tried to access your site, I feel it quite heavy to load...getting stuck..
"Play for fun with a small bet amount 0.002-0.02btc" does it mean that the minimal bet is 0.002 and max bet is 0.02btc?
If the answer is yes, I think your minimal bet is quite high...and I believe this is not a good start to a new site. Perhaps you need to reduce the minimal bet..
One more question, is your game provably fair?

[GrandmaJean]

maximum bet is really low i think, minimum bet is also high, i think you should let people bet from 0.0005 to the amount that your funds let

[catbref]

Thanks for the replies already!

Right now it uses arc4random_uniform() to generate winners but retrospective provability will be coming soon.

Min bet is 0.002 BTC, max bet is 0.02 BTC but I can change these very easily.
I was a bit worried about transaction fees swamping the minimum bet but I don't mind lowering it.

Any comments on the user interface? Is it too complicated to work out how to use the site?

[98problems]

i think lowering the minimum bet and making bigger maximum would surely attract a lot of players to your game who would like to try it out

[catbref]

OK, I lowered the min bet to 0.0002 BTC. When more people try it out and report back then I'll raise the upper limit too!

I have see the site with 2 pc/ip different, and the address for deposit is the same for all users? 1DerbyR7HJfEcRdhzaK4gwQgyXZ52co2r7  ??

[catbref]

yes but it varies depending on which horse you want to bet on:

red: 1DerbyR7HJfEcRdhzaK4gwQgyXZ52co2r7
blue: 1DerbyBW6CEfYSwRgceEHtk72jottXcUUc
green: 1DerbyGZZfN1yZpHKx8vTY167X3NDwPutQ
yellow: 1DerbyY8osKYeUs5kq967MLTpSz7AdWBLP
white: 1DerbyWua9JtbwafFSsvdKvFYn91kuDnzB

winnings get sent back to the player's sending account

I'd say that it is not a deposit address, but bet address. The way you play the game is like in Luckybit, it is a on-chain game. Players will need to pay miners fee for every single bet.

If you worry about the transaction fees, better to change your game into off-chain game.
And when a player win, who will pay for the miner fee? your site or the player?

[jeannemadrigal2]

Ha!  Nice game, I remember this type of game.  Too bad I always loose when I play it lol.

I saw the white horse winning, but im afraid to see the max multiplier winning when im watching it feels like this are only for show to attract players then they manipulate the rolls

Site pays transaction fees for winnings.

The white horse has to win SOMETIMES!
Also, the race you see is exactly the same race other people on the site see - at the same time too!
Multiple people could be betting on the same race.

---edit---

Just to clarify - because everyone sees the same race at the same time then there's no possibility that you're seeing white horse wins to reel you into playing.
Also, winners are currently generated using arc4random_uniform() but I can see provability is an urgent feature I need to address.

[JamesCB]

Max bet * max multiplier = .5btc


Care to show proofs of your bankroll? Can you pay several users hitting max multiplier?

[marioantonini]

thanks panjul07, now i have understand.
But someone have test the game and received a payment?

[tiggytomb]

I remember these games in the arcades, still there in some local ones.  I see that you need to select your horse and then send your coins to the address supplied, maybe I have missed something but it would be nice and a bit quicker if you could top up your account and not have to select and then send coins each and every time.  Would be interested to see if anybody hits the big one and if you are able to pay out multiple winners.  Cool game though, brings back some memories

[catbref]

I think you're right: it looks like we need to add some form of registration so people can load up their account and play by just pressing the "Bet Now" button.
Would save a lot of fees!

I think I have an idea of how to do the provability - will get back to you when I've tested it.
Pretty much time to go to bed here though.

[panjul07]

thanks panjul07, now i have understand.

I think no one played the game so far, since there is no provably fair verifier yet and there is no statistics on the site.
Hope those two things will be added as soon as possible.

Yes that site looks weird and horrible to play there without provably fair system, i think OP will explain how this site generate the bet result and i cant be manipulated on big bets, statics will nice addition to see how much wagered there and who got big profit there. these addition can build trust to get active players.
