Requirements

Defining requirements for a project is extremely important because without a map or an outline, one might work towards something that might be completely unnecessary, wasting good amount of time/resource available.

Basic

• The player must be able to guess the combinations of numbers
• The player must be able to see their previous guesses
• The number of remaining guesses must be displayed
• The player guesses a combination of numbers and the server provides a feedback (calculate_bulls_and_cows(), submit_guess())
• The player must guess within the number of allowed attempts (num_of_guesses) to win
• The server randomly selects a pattern of selected secret code length (code_length) from a specified number of colors (num_of_colors)
• The game must use Random Number Generator API to generate the number combinations (get_random_number())
• Game configuration should be flexible (players can specify code_length, num_of_colors, and num_of_guesses in a room)

Multiplayer

• It must be multiplayer using websocket. (real-time communication)
• Game state must remembered after refreshing the page or when leaving and re-entering the room. (browser must save data on local storage)
• Player must know when other players have joined the game
• All clients in a room must be kept in sync
• Since it’s multiplayer, the game must have a User model for usernames
• Login must be secure
