Greetings guys and girls, I`m very excited to present you the FIRST and REALLY WORKING Ethereum based dice game. The other dice games had bad random number generators. I have fixed it, this is the final version of my dice game!

The dice game is Exciting and Unique, and it's an attachment to EthVenturesFinal, meaning that the fees from here goes to EthVenturesFinal investors and not to me Smiley !






How it works?

You must deposit minimum 0.1 Ether, and you have a 25% chance of Winning the entire Balance, and there is No House Edge. The average prize is 0.4 ether, for 0.1 Ether deposit, a 0.3 Ether Profit for every Winner. It's provably fair, you can verify the source code!

There is also a Jackpot Feature, for every 40th depositor can win the jackpot which accumulates over time, as 15-20% of the deposits goes to this pool. This means that the Jackpot will be on average
0.8 Ether!






Features:


 • Adjustable House Fee: Currently set to 5%, it will be lowered after big volume
 • Adjustable Minimum Deposit: Currently 0.1 Ether
 • Adjustable Owner: Casino can be sold to new manager if needed (I`m not planning selling it)
 • No House Edge
 • Provably fair & no advantage to anybody
 • 25% chance for winning 400% profit on every gamble
 • Jackpot for every 40th player, for 800% profit
 • 100% Open-Source, Transparent and Bug-Free






How to gamble?

Send minimum 0.1 Ether here, the prize will be sent back automatically to the address you sent from:
0x78b058ccda93816487c655367dcb79664a216ad2







Source Code:


You can see that I have many test contracts linked to the creator address and many more on other ones, so I`ve tested this very thoroughly, and I can safely say that it's bug-free and works like a charm! The current version is the final one, so I wish you happy gambling and big wins!

Hmm this one looks better dude, much much better than the previous, it seems like you have been working hard in the past days.

I really like that, you are a very dedicated person to your work, and that can be admired in a developer.

The randomizer is definitely improved over the last one!  However, it's still not a 25% chance, I think it's more like 50%!!

Code:
if(uint(sha3(gamblerlist[list_length].etherAddress,list_length))+uint(sha3(msg.gas)) % 2==0 && Bankroll > 0) //if the hashed length of your address is even,
{   //which is a 25% chance, then you get paid out all balance!

This first piece of the conditional is not random and doesn't serve much purpose: uint(sha3(gamblerlist[list_length].etherAddress,list_length))

A player can know ahead of time what their address is and what the list_length is and can perform an sha3() on that.  You can not use already known data to generate a random number.

The next part of the conditional is trickier: uint(sha3(msg.gas))

In this case the sha3() is being performed on the gas that was spent.  I'm not certain what is involved in calculating that number, this may well provide an acceptable amount of entropy, or at least a greater challenge to calculate.

When you add those parts together you end up with a single very large number: uint(sha3(gamblerlist[list_length].etherAddress,list_length)) + uint(sha3(msg.gas))

The problem is that very large number is being run through a modulus of 2:  % 2==0

That will return either a 0 or a 1 depending on if the number is even or odd, which is a 50% chance, not 25%.  You probably want to use % 4==0 to determine if your pseudo-random number is divisible by 4.

The odds of winning this are actually 50/50  Cheesy

Looks like players start to play it, it's good, and the attachment works flawlessly, dividends are also being paid out  Smiley

No One is playing, look at transaction history.


Only OP chatting with his multiple accounts to promote his scam.

Have a feeling BetGod is also this guy, www.bitcointalk.org/index.php?action=profile;u=687379 (btc-raffle.com)

Just the way he seems to be pretending to be a good programmer to impress while complimenting himself with many alt accounts.

I could be wrong though.
I know what I can't be wrong about:
He is idiot.

It's not working!

The transfer to the Ethventures Contract ran into an error. And not any dividends where paid out! See https://etherscan.io/address/0xee462a6717f17c57c826f1ad9b4d3813495296c9#internaltx . After Block 1307118 there was no payment to the investors.

People should learn to use and show test contracts before claiming things work flawlessly.

Now 1/4 chance to win nearly nothing.

How can we play if there is nothing on the contract?

This would have been a good idea if you had done it when you already had 4-5 well established and profitable apps. It's pure speculation otherwise.
