Mancala Game

How to Play

1. Run docker compose up.
2. Open localhost:8080 in your browser—this is the first player’s game perspective.
3. Create a new game and copy game ID from an input field.
4. Open localhost:8080 in another browser tab—this is the second player’s game perspective.
5. Paste game ID in an input field and click Connect.
6. The game has started. Use board buttons to make turns. Switch browser tabs to switch between players.

Reasoning Behind Technical Decisions

1. Domain objects are immutable—thus they’re thread safe and easy to reason about.
2. Game logic is presented as a set of rules, connected into a Chain of Responsibility. It allows us to keep the code neat and clean and to test small chunks of logic separately.
3. Redis is used to store game state as a serialized string. If at some point we need more sophisticated approach (e.g. to search games by their status), we may want to switch to MongoDB or even to RDB.
4. Frontend is quite primitive—it’ll be easy to switch to a prettier one because API is documented with Swagger.
5. In a production environment we’ll want to pay attention to API’s security. However, I decided that this topic is out of this assignment’s scope.
