So to everyone posting issues. I really helps a lot if you also post your error/logs. I see a lot of people just post a question, and not get any feedback. The easiest way to post you logs is to use gist and then post the link with your question - https://gist.github.com/

Hi, I'm from Chile. In my country we have a serious problem with corruption. I would like to be able to apply the blockchain technology in my local municipality. They know of some tool that can allow me to achieve greater transparency in the expenses of my municipality.

@mustafa92348 The secretNumber is visible to everyone. So, a player can just check the secret number and then call play.
phiferd
@phiferd
Although, running this in remix, it looks like there is something odd happening. I wouldn't suggest playing. :)
phiferd
@phiferd

nice. Added a log statement before the check:

        emit Played(number, secretNumber);
        if (number == secretNumber) {

output in Remix

{
        "from": "0x038f160ad632409bfb18582241d9fd88c1a072ba",
        "topic": "0x2ed17a434754b5adc8698800cd2ceb72b8e24735a9bfcc62f7b542161a7c2208",
        "event": "Played",
        "args": {
            "0": "12",
            "1": "1154414090619811796818182302139415280051214250812",
            "number": "12",
            "secret": "1154414090619811796818182302139415280051214250812",
            "length": 2
        }
    }

This is fascinating. Either I'm missing something obvious, or there is some low level bug here. Again DO NOT PLAY. You won't win.

hi
how to text comm in cantrract?
phiferd
@phiferd
My guess is that it has something to do with the way uint256 is converted to text. When converted to text, it appears to be a number between 0 and 16, but it's really not.
phiferd
@phiferd
Credit to @MicahZoltu for noticing that the assignment of game.player is overwriting secretNumber. game was not initialized normally, so its storage starts at the same offset as the contact. Assigning the first field of game overwrites the first field of CryptoRoulette. clever. :)
phiferd
@phiferd
Just and FYI, I opened an issue to see if the solidity team can prevent this sort of scam in the future. ethereum/solidity#4315
