Build a console-based (i.e. runs in terminal) unix-compatible interactive card game. You can pick Blackjack, Solitaire, Memory, or any other game of your choosing (please include game rules in this case).

Along with your code, include a design document covering:

1. Instructions for running your code and any tests you may have written
2. Rules for your card game, if not one of the three listed above
3. A brief explanation of your design choices and any data structures or algorithms that you implemented
4. Choice of tooling (language, libraries, test runner, etc.) and rationale behind those choices.

1. The card game can be single or multiplayer
2. Many card games rely on the cards of a player being hidden from other players. You may want to consider implementing such a feature.
3. Feel free to use any programming language.
4. Please cite any external libraries that you use.
5. We suggest you spend no more than 3 hours on this challenge.

You will be assessed on your creativity and the quality of your code and design document. This includes, but is not limited to, the following:

1. Does the game work, i.e. is it possible to play a complete game of the card game you chose?
2. How thoughtful were your system design decisions?
3. Is the game designed well / easily playable?
4. Is the code organized, modular, and well-factored?
5. What edge cases were considered and accounted for?
