Mastermind game, which can be played by a user "against" the computer. This is a game where a player tries to guess the numberc ombinations. At the end of each attempt to guess the 4 number combinations, the computer will provide feedback whether the player had guess a number correctly, or/and a number and digit correctly. A player must guess the right number combinations within 10 attempts to win the game.

At the start of the game the computer will randomly select a pattern of four different numbers from a total of 8 different numbers. A player will have 10 attempts to guess the number combinations and only 5 minutes. At the end of each guess, computer will provide one of the following response as feedback:

• The player had guess a correct number
• The player had guessed a correct number and its correct location
• The player’s guess was incorrect

• Clone the repo and install the dependencies.

git clone https://github.com/SvitlanaAno/MastermindGame.git

• Open Android Studio and create a new project from the just downloaded source.

• Run the app on an emulator or directly on a device.

• Android Studio version 2020.3.1 or newer
• Java 11

The app is implementing the MVVM pattern and consists:

Four Screens, each screen is implemented as a Fragment

• TitleFragment - dispalys screen with play button and rules button.
• GameFragment - dispalys available for selection number 0-7( in the aspect of UI view the number are fixed) and combinations of 4 selected numbers, the number of guesses left and a timer, also dispalys a list of all the history of guesses and their feedback.
• ResultFragment - dispalys score of the current game and total score of user games, and restart an reset button.
• Rules Fragment - displays the overal rules how to play the game.

Two ViewModels

• GameViewModel - consist mastermind game logic.
• ResultViewModel - consist logic to retrieve current score value using Safe Args and user total game score value from Preferences DataStore.

Model and Network packages includes:

• Guess - data class for creating guesses objects.
• UserPreference - class Creating, observing from and writing user total game score to a preferences dataStore.
• SecretNumberApiService - for making api calls to an HTTP web service and retrieve Secret random number.

• Navigation component within Jetpack to move the user between different screens.
• Transformation map
• Data Binding in XML files
• ViewModel Factory
• Using Backing Properties to protect MutableLiveData
• Observable state LiveData variables to trigger navigation

• Android architecture components
• ViewModel
• LiveData
• DataStore
• Retrofit

Use Random Number Generator API (https://www.random.org/clients/http/api/) to generate the number combinations.

• add tests
• add view to guess history to show how many number correct and on the right position
• add settings screen for difficulty level selection
• add animation on the result screen
