Capture the Ether Writeup

This writeup is a runthrough of challenges at https://capturetheether.com/challenges/ built on the Ropsten testnet. I will go through each problem in four steps:

1. The intention of the contract
2. The flawed assumption
3. The process of exploiting the vulnerability
4. The potential patches

I'll provide examples of the code I wrote as needed. To save time, we'll skip into the Lotteries section, starting with Guess the secret number, as that's the first problem which truly required some thought.
