本节主要就是一个新手教学，让人先了解游戏玩法及闯关模式，需要对 MetaMask、JavaScript、console等有基本了解。
打开 Developer Console (F12) ，输入
会打印当前钱包地址。
依步骤了解指令用法，按 Get new instance 开始闯关。MetaMask 会弹出交易请求，确认以部署关卡合约，关卡正式开始。
打开 Developer Console (F12) ，依次输入:

| > await contract.info()
< "You will find what you need in info1()."
> await contract.info1()
< "Try info2(), but with "hello" as a parameter."
> await contract.info2("hello")
< "The property infoNum holds the number of the next info method to call."
> await contract.infoNum()
< BN {negative: 0, words: [42, empty], length: 1, red: null}
> await contract.info42()
< "theMethodName is the name of the next method."
> await contract.theMethodName()
< "The method name is method7123949."
> await contract.method7123949()
< "If you know the password, submit it to authenticate()."
> await contract.password()
< "ethernaut0"
> await contract.authenticate("ethernaut0")

最后会弹出一个 MetaMask 的交易请求，确认后再按 Submit instance，再确认后 Console 会弹出 “You have completed this level!!!” 即本关完成。
