Overview

Cryptolotto is a powered by Ethereum DApp (decentralized application). The backend code is running on a decentralized peer-to-peer network and is presented by 8 smart contracts and a front-end. Cryptolotto works autonomously and with no entity controlling the key functions. The Cryptolotto's data and records of operation are cryptographically stored in a public, decentralized Ethereum blockchain network.

The main idea of Cryptolotto is straightforward: people from all over the world contribute equal amounts of ETH to one wallet during the set period of time. When a timer ends, this smart-contract powered wallet automatically sends all received ETH to one randomly chosen wallet-participant.



How to play

  • Use an Ethereum. To start playing, you should have one of these wallets: MetaMask, Ethereum Wallet, Parity Wallet or MyEtherWallet. Top up your wallet with enough amount of ETH first, before you start to play.
  • Select your Game. 5 games are running simultaneously. Each game has different duration and entrance cost. Entering the same one game more than once  is allowed. Also, you can join all games at the same time.
  • Copy the wallet address. Be sure to send your funds to the right wallet address. Each game has its own unique address presented on the Home page as well as on our official Github page.
  • Send your funds. Each game has its own price. To join the game, you need to send the right amount of ETH to the given address. If you get everything right, you will find your wallet address in the list of players.
  • Wait for result. Join our Telegram channel to receive notifications about Jackpot winners. If you are the winner, then you will receive all the Jackpot amount back to your wallet immediately after the end of the game.

The algorithm of picking a winner

Code:
   }
    
    function randomNumber(uint min, uint max) public constant returns (uint) {
        uint random = uint(keccak256(
            block.timestamp *
            block.difficulty *
            block.number *
            uint(block.blockhash(block.number - 1))
        ))%10 + 1;
      
        uint result = uint(keccak256(random))%(min+max)-min;
        
        if (result > max) {
            return max;
        }
        
        if (result < min) {
            return min;
        }
        
        return result;
    }

Quote
Each wallet-participant gets ${uint _number} when he joins the game. Random number determination depends on current block timestamp, block difficulty, block number and previous block hash. We set determination between min and max values. Additional conditions, in case something goes wrong, are set to prevent contract from sending Jackpot to invalid address.

Thank you for your feedback, we really appreciate it.

Currently, the shortest possible games are the Short 10m and Gold 10m games. A draw in these games is happening every 10 minutes. The difference is in the entrance cost.

We believe that 10 minutes is an optimal duration for the most shortest game. Making it even shorter will lead to a problems in case of the Ethereum network overload (a transaction processing time may be easily longer than 10 minutes).

are you the dev?


No, but he is somewhere aroud here Smiley Do you have any development-related questions? We would be glad to answer.
