Ethereum allows transfers to selfdestructed contracts so even in that situation it shouldn't stop the game. My bad. Anyway, just replace "self-destructed" contract with a "contract that causes error". |

Source code of smart contract is not designed properly.
Owner can take all the money bypassing the rules of game.
If you are referring to reentrancy attacks by external contract calls, Ethereum was updated in late 2016 to prevent "transfer" function from having enough gas to carry out such an attack. No, it's not about reentrancy. Steps to attack: 1. addEntry() 2. changeContractFeeAddress(destroyed contract) And now nobody can addEntry() 3. wait and claimLottery() to get whole balance |

Here is solution.
User Satoshi generates random string (secret #1).
User Satoshi creates a game and sends hash of secret #1.
User Nakamoto generates random string (secret #2).
User Nakamoto joins the game and sends hash of secret #2.
Both players receives opponent's hash and sends its secrets.
Server calculates winner based on both secrets.
A player who has not sended his secret loses.
Also it may make sense to add an additional secret and hash from the server.

An Official Notice has been released:🚀 Crash has arrived! Come check out the new and first ever multiplayer game mode at http://Stake.com ! This crash is not multiplayer game as the players do not interact with each other at all. It is a multiplayer game since more than 1 Gambler bets on the same time on the same payout.

Multiplayer: https://en.wikipedia.org/wiki/Multiplayer_video_gameMultiplayer games allow players interaction with other individuals in partnership, competition or rivalry, providing them with social communication absent from single-player games. Multiplayer: https://en.wikipedia.org/wiki/Multiplayer_video_gameThe crash game at Stake is a multiplayer game, the main idea of multiplayer game is by giving opportunity for more than 1 players to bet on the same game. If your main concern is about the "interaction", yes there is an interaction between players through the chat feature. Players are communicating on the chat while betting on the same bet(s). If it is not a multiplayer game, I'm curious to know which kind of game which can be considered as multiplayer game in your opinion? So, dice is multiplayer too, since players can chat? Multiplayer gambling - this is when the players' stakes affect each other's winnings and loses. Like bustabit v1. |

Hi, just been found this thread, and had a look around the site
In the thread it is reported that 1% is deducted, which is brilliant.
But on today's football matches(champions league qualifers), the current odds are suggesting >5% deduction
For example current odds for the 3 possible outcomes 5.462, 2.731, 1.986
Have not read all of thread, have you changed from 1% deduction?
5% is basic onehash house edge for all events. Onehash never reported it's house edge. At least I have not seen. |

More importantly though, is what we've seen on our game though and in fact, after some recent very large wins from players, that number is actually only .11% right now. Looks like you mixed up the profit of investors (0.113% right now) and the practical house edge (1-99.690% = 0.310% right now). The difference is "only" three times. |

If your goal is to actually understand how the game works I understand how original bustabit v1 concept works. consider reading our FAQ as you can find the relevant points below in there. I didn't find link to faq page anywhere on game site  Anyway, there are mistakes. For example, this one: 1% of games will instant bust (0x) and no bonuses will be awarded Chance of instant bust is lower - 1/101. Simply put, low multipliers have a lower house edge. The house edge (margin) is scaled between 0 (1.01x) and .99...%(~20x). House edge is 0 at 1.00x, not at 1.01x. Same bad as with faq page. Did not find link to this page anywhere on the site. So why did we say .75% and not 1%? The reason for this is pretty simple. If you look at the realized HE for trusted BaBv1 games in the past (including BaBv1 itself) it comes in most often between .2-3%. More importantly though, is what we've seen on our game though and in fact, after some recent very large wins from players, that number is actually only .11% right now. That is to say, the house edge that we've realized is actually much lower than .75%. BaBv1 games is not your games. Other players played there with other tactics. In the end, your margin does not correspond neither to practice, neither to theory, it is simply taken from your head. Since the edge of the house - the key point of gambling, it is unfair misrepresentation. In addition, you can see for yourself that calculating of house edge on practical data is extremely stupid idea. After a few more large wins from players, will the house edge become negative? And you will tell this nonsense to users and investors? House edge is between 0.5% to 1.5% according to cashout multiplier in case of getting average bonus (0.5%). End of story. Again misleading graph which corresponds to the BaBv1, not to ethercrash. Correct one (x-1)/(x-0.01)+0.5:  |

Ethercrash used to have a 1% social bonus prior to it being reduced to 0.5%
This is why the current stats reflect that the house has paid more than 0.5% out in bonuses.
Well, that's reasonable. But still there are great problems with margin. So looks like 0.75% is an average house edge between previous average house edge (0.5%) and current average house edge (1%). Clever manipulation. |

1% of games will instant bust (0x) and no bonuses will be awarded, all other games have bonuses equal to 0.5% of the amount wagered. So, players will get about 0.495% of the wagered amount in bonuses. Total Wagered: 1,091,106.88 ETH
Players won in bonuses: 9,228.14 ETH Won in bonuses: 0.845% of the wagered amount. So how can it be that the actual value is so far from the mathematically calculated value? We recently got a few big winners who won over 1700 ETH togheter, we have also switched to this higher house edge since just a few months (it used to be 0-1%) Are you site's owner? Do you understand how it works? Do you understand what you are saying? That is complete bullshit. Big wins or big loses of players does not affect bonus in any way. Let's look at instant-busted round. All players get 0% in bonuses. And let's look at normal round. All players get 0.5% of total wagered in bonuses. And now it is obvious that players receives from 0% to 0.5% of total wagered in bonuses. It's impossible for players to get more than 0.5% in bonuses. But your stats page says it's about 0.845%. In the end, your stats page is bullshit. "Players won in bonuses: 9,232.68 ETH" - lie. "Players won in total: 1,088,749 ETH" - lie. "the current return to player is 99.698%" - lie. "0.75% average house edge" - lie. |

How did you calculate average house edge? According to my calculations, house edge is between 0.5% and 1.5%. And that is 1% average house edge. Our house edge is dynamic, the current return to player is 99.698% , the way we have calculated the average was from the players betting history and cash out targets. If current return to player is 99.698%, then average house edge is 0.302%. So, again, what's about 0.75%? |

Code of smart contracts are vurnarable. It's easy to revert transaction that does not pay to you. And to try one more time after that with other random number in next block. So i strongly do not recommend to gamble at that site.
i invite you to try to hack our website, our website is full decentralized and run on ethereum blockchain. Im very sure you can't we already spend more than 1 month to test all vulnerabilities and we can guarantee that the jackpot goes into normal parameters without any problems. As i can see you have 0 knowledge on solidity code. To hack your site? But I was talking about a smart contract, not about the site. And your website does not run on ethereum blockchain. Blockchain is not about websites. If you are guarantee the security of your contracts, then let's play against each other! Since it's impossible to hack contract without any funds on it. 1vs1 jackpot https://galaxyeth.com/jackpot/1vs1jackpot.htmlcontract https://etherscan.io/address/0x559cd99b1eb1cd61224d9d2a9aec3f8634bfbef4I'm waiting your bet, at least 5 Eth. |

There's a problem with your provably fair method (you copied the bustabit scheme, without doing the "seeding event" to prove that the hash chain itself is fair). In other words: you are proving the games are predetermined, but you're not proving they're from a fair distribution. Does this qualify for the 100 ETH bounty?
Yes, it is obvious that manipulation is possible. So, it's qualify. Congratulations) |
