BTCDice is now open to the public!  

http://btcdice.com

BTCDice is a lucky number Bitcoin betting site with up to 64,000x payout and an expected return of 98+%. The house pays out on every bet, win or lose.

To play, place a bet to one of our game addresses and wait for a return transaction. Most transactions are returned within just a couple seconds.  The house uses highly interconnected nodes with more than 800 connections, each, to the bitcoin network in order to maintain the fastest possible payments and transaction detection.

If you win, you'll get (your bet * the game multiplier) - house cut and 0.0005 transaction fee. If you lose, you'll get ((0.005 * your bet) - house cut), or 0.00000001, whichever is larger.

The house does NOT require confirmations before sending back your winnings, except on bets that are above the max or below the minimum bet for the game.

In order to play, you must be using a wallet that allows you to receive coins back to the same address you send them from.

To see how it works, try sending a 0.01 BTC bet to 1BTCDiceLs79syendE1DM1XCaHcKkzBNnP which is our game address that has a 73.2422% chance to win, and pays out 1.365x your bet.

At the time of posting this, BTCDice offers higher payouts and lower house percentages than SatoshiDICE.

We support a full JSON API for looking up transactions, addresses and games, to make writing software to interface with our platform easy.

I hate to be this guy, but your website is nearly a clone of SD as is the game.
Good luck but may i suggest employing some originality.

Adding to my list under pending.

Competition in a free market is a good thing.

This is completely true, SD has suffered several outages and if you play your cards right you will be there to fill the needs of the gamers next outage

I don't know if I should be telling you this or not, but you calculated your payouts wrongly.  In some of the games your house edge is negative.

You made 2 mistakes:

1) you pay out 0.5% on losing bets, which you don't take into consideration
2) you need to multiply by 0.98, not subtract 0.04 to get a 2% house edge

Look at your "lessthan 2" bet for instance.  I have a 1-in-32768 chance of winning, and when I win I get 32767.96x.  When I lose I get 0.5%.

If you ignore the 0.5% for losing, the house edge is 100-(100*32767.96/32768) = 0.0001%.

But when you take the 0.5% for losing into account too, the house edge goes down to 100-(100*(32767.96 + 32767*0.005)/32768) = -0.49986%.

ie. you're losing 0.5% of each bet in the long term.

Here are the correct house edge details for each bet:

under     1 : house edge =  1.844%
under     2 : house edge = -0.500%
under     4 : house edge = -0.500%
under     8 : house edge = -0.499%
under    16 : house edge = -0.499%
under    32 : house edge = -0.498%
under    64 : house edge = -0.496%
under   128 : house edge = -0.491%
under   256 : house edge = -0.482%
under   512 : house edge = -0.465%
under  1000 : house edge = -0.431%
under  1500 : house edge = -0.398%
under  2000 : house edge = -0.363%
under  3000 : house edge = -0.292%
under  4000 : house edge = -0.225%
under  6000 : house edge = -0.091%
under  8000 : house edge =  0.049%
under 12000 : house edge =  0.330%
under 16000 : house edge =  0.599%
under 24000 : house edge =  1.136%
under 32000 : house edge =  1.697%
under 32768 : house edge =  1.750%
under 48000 : house edge =  2.820%

I only noticed this because of how close your payout on under 48000 is to SatoshiDice's payout.

And here are the correct payouts to make the house edge really be 2%:

edge=0.98; max=65536; lose=0.005

         4000,6000,8000,12000,16000,24000,32000,32768,48000:
  print "%5d %9.3fx" % (n, (max*edge - lose*(max-n)) / n)

    1 63897.605x
    2 31948.805x
    4 15974.405x

Good to see Dooglus yet again helping out site admins  

[BTCDice]

Thank you for the notice.  I would hate to have lost a bunch of BTC over the long run.
I've corrected the issue.

[BTCDice]

House edge has been reduced to 1.8% to stay competitive.

Place your bets!

:-)

Where does it end!

[BTCDice]

I have another update that is sure to make users happy!  

• Reduced house percent to %1.65.
• Increased Max Bet to 100 BTC on less than 48000, 32768, 32000, and 24000 games.
• Increased Max Bet to 50 BTC on less than 24000 and 16000 games.

Have Fun and Good Luck!

You run the same risk as anybody using your site.  You can very easily go bankrupt.  I've done some simulations of SatotshiDice and despite a house edge of 1.5% in a nontrival number of runs SatotshiDice goes bankrupt (most of the time the gambler goes bankrupt).  I didn't take into account the reduction of the max bet or the increase of the house edge which is what SatoshiDice used to counter this problem.

You are also risking legal problems.  Where I live (Massachusetts, United States) this is illegal.  The creator of SatoshiDice actually sold his site to someone else to avoid this risk.

[Maged]

It appears that you aren't taking extremely necessary precautions to protect you from losing all of your money. You have no idea how much work SatoshiDice put into protecting themselves behind-the-scenes. If you can't figure out the problem I'm referring to, you should shut down your site now and give up.

That is funny. 
I am tracking down a bug that is missing a few bets.  Sorry about that.

Your payment has been paid.

Good Luck!

[opticbit]

wish I had started playing before douglas had anything to say.

only played one round, I'm up .03 btc.  good enough.

Nice clone.  (satoshidice.net is a bad clone- reports of not paying out.)

[LuaKT]

Anyone else having issues when sending payments with sendmany?

I sent this transaction: https://blockchain.info/tx-index/13069740/d865f6929497516968ccb1bee9f8df1d5e47254f23c3dabdce23ed0fc9722279?show_adv=true
Which contains 5 payments of 0.2.

The corresponding transaction on BTCDice is this: http://btcdice.com/details.html?q=11435 which is showing as I only paid 0.2 BTC total.

Am I going insane or is it bugged?

I looked at transactions and see the problem. You sent multiple payment to the same bet address in the same transaction which main client does not support, and I do not support due to potential double-spend attack. The server only supports main client functionality. I will send back your whole bets as good faith gesture and in the future you must send single bet per address in each sendmany.
