Tic Tac Toe

A secured web app to play Tic Tac Toe against a dummy computer opponent.

Features & Notes

• Play a game on a 3x3 board with an option to go first or after the computer opponent.
• Computer opponent's AI chooses random squares, except when going first in which case the center tile is always picked.
• User game data is persisted to an in-memory database. As long as the server is not restarted, a player can leave and return to finish an in-progress game.
• App is secured with a username & password login. Database is seeded with two usernames rick and morty. Both have the same password pickle.
• UI renders each time through a full page refresh in the name of simplicity.
