Getting ready
You need to have a working installation of Ethereum (geth, Parity, ganache, and so on) or the Remix IDE to test this recipe. The contract inherits the winnable lottery contract created in the previous recipe. It is recommended to step through it before continuing with this recipe.
The contracts given are for illustration purposes only and cannot be used in real-world systems. It is also recommended to use SafeMath for arithmetic operations.
