Contract Puzzles

The goal of the Smart Contract puzzles is to work on reading smart contracts and writing good tests to modify those smart contracts.

Each Game contract will have a storage variable called isWon:

bool public isWon;

The objective is to set this isWon to true without modifying the smart contract.

At the same time, you're more than welcome to use console.log from hardhat if you need to debug your smart contracts.

Running the tests

First, install all the dependencies with npm i. Then, you can run all tests at once by running npx hardhat test. However, this might be frustrating when you are just trying to test an individual game.

If you are working on Game1, for instance, it will make more sense to run the test cases for the first game: npx hardhat test test/game1Test.js. Each Game contract will have a corresponding test file.

Your goal is to modify the tests to make the test case pass without modifying the smart contract (and leaving the isWon assertion in place).
