Introducing the first ever roulette program doing provably what it supposed to do.

Personal Note

I understand that neither this nor the previous pyramid scheme adheres to some high moral compass.

I'm very much a believer of this project and what it stands for and have been ever since I first heard of it.

For me this is about growing as a programmer while sharing some little program-contracts, I myself would've liked to have, with the community.

Authenticity

To check that the roulette.sol contract is actually the one on the ethereum blockchain, compile it with optimizations enabled, at https://chriseth.github.io/browser-solidity/ and compare the resulting Bytecode with the output of web3.eth.getCode('0x5fe5b7546d1628f7348b023a0393de1fc825a4fd');

Init Contract

In geth console type:

var rouletteContract = web3.eth.contract([{"constant":true,"inputs":[],"name":"casinoBalance","outputs":[{"name":"","type":"uint256"}],"type":"function"},{"constant":false,"inputs":[],"name":"kill","outputs":[],"type":"function"},{"constant":false,"inputs":[{"name":"amount","type":"uint256"}],"name":"casinoWithdraw","outputs":[],"type":"function"},{"constant":false,"inputs":[{"name":"number","type":"uint256"}],"name":"betOnNumber","outputs":[{"name":"","type":"string"}],"type":"function"},{"constant":false,"inputs":[],"name":"casinoDeposit","outputs":[],"type":"function"},{"constant":false,"inputs":[{"name":"color","type":"uint256"}],"name":"betOnColor","outputs":[{"name":"","type":"string"}],"type":"function"},{"constant":true,"inputs":[],"name":"welcome","outputs":[{"name":"","type":"string"}],"type":"function"},{"inputs":[],"type":"constructor"}]);
var roulette = rouletteContract.at('0x5fe5b7546d1628f7348b023a0393de1fc825a4fd');

roulette.welcome.call();

web3.fromWei(roulette.casinoBalance.call(), "ether");

Bet on Number

In geth console type:

var number = 17; // Number to bet on

var amount = 5; // Value has to be between 1 ETH and 10 ETH

roulette.betOnNumber.sendTransaction(number,{from:eth.accounts[0], value: web3.toWei(amount, 'ether'), gas: 400000});
web3.fromWei(roulette.casinoBalance.call(), "ether");
web3.fromWei(eth.getBalance(eth.accounts[0]), "ether");

assuming eth.accounts[0] is the desired account, otherwise change it.

Bet on Color

In geth console type:

var color = 0; // '0' = red, '1' = black

var amount = 5; // Value has to be between 1 ETH and 10 ETH

roulette.betOnColor.sendTransaction(color,{from:eth.accounts[0], value: web3.toWei(amount, 'ether'), gas: 400000});
web3.fromWei(roulette.casinoBalance.call(), "ether");
web3.fromWei(eth.getBalance(eth.accounts[0]), "ether");

assuming eth.accounts[0] is the desired account, otherwise change it.
