How to play the game
Prerequisites
  1. To play this ethereum roulette you will firstly need to install Metamask Plugin. You can find more about Metamask on their website
  2. Blockchain games consist of a web frontend, which is the page you currently view and also an Ethereum contract which you can think of as the 'backend'. The contract of this game is currently deployed on the "Ropsten" test network. On test networks, unlike the "mainnet" ether does not cost you real money and you can ask and receive it for free. The second step you need to do is receive some free ether. For this purpose you can use any of those sites: Or you can google for "Ropsten free ether". Requesting just 1 ether would be enough.
  3. Once you verify that Metamask sees your newly received ether on the Ropsten test network, you are ready to play!
Gameplay
  1. The initial game status would be "Expecting your bet". When in this state you can click on the betting board and little input fields would appear. The ether unit used throughout the game is "Finney", that is 1/1000 of an Ether. Your minium bet is 1 Finney and your maximum bet is 1000 Finney.
  2. You can bet at maximum of 10 positions. The maximum bet at single position is 1000. The maximum sum of your bets is 5000. Once you are ready you should click on "Place bets". The system will list all your bets along with some calculations on what your maximum profit is. A check will be made if the contract has enough balance to pay your eventual win.
  3. When you make sure that the system has correctly previewed your bets you can click on "Send bets" button. That action should pop-up an Metamask window which will request your authorization. You authorize the Metamask plugin to send your request on the blockchain by clicking "Submit".
  4. Once your bet is sent on the blockchain, you will have to wait for the next block to get mined. The game state will be "Waiting for next block. Please wait...". You may have to wait up to a minute.
  5. The random hash number of the next block will determine what the winning number is. Once it is known you will have the option to claim your bet.
  6. Another Metamask window will pop-up asking for your authorization again.
  7. Finally game outcome fields will appear which will summarize what the outcome is.
