+# Mastermind game 🧙‍
+
+A quick and dirty Mastermind single-player game implementation.
+
+https://scmx.github.io/mastermind
+
+The computer opponent decides on a code and you make guesses as to what the code
+is. When you've made a guess for all positions on a row, you instantly get the
+results and move on to the next row unless you just won. :tada:

+
+## Technologies
+- Modern JavaScript (but no transpilation)
+- CSS flexbox
+- [Hyperapp](https://github.com/hyperapp/hyperapp) - JavaScript
+micro-framework with virtual DOM, state management
+
+## References
+- https://en.wikipedia.org/wiki/Mastermind_(board_game)
+
+## Gotchas
+- Bad UI and UX
+- No tests
+- Big ugly view component
+- No JSX, used `h('div', {}, [...])` instead to try it out :unamused:
+- Very cheatable
+- Soon to be an intentionally abandoned side project
+
+## Challenges for you
+- Write your own version?
+- Write a two-player version?
+- Move opponent logic to a server to remove ability to cheat?
+- Write an isomorphic game server that can be run either in node or in the
+  browser?
