Skočko

Mastermind game

Overview

This is an Android mobile app project that:

• showcases Mastermind game
• uses MVVM architecture
• is inspired by a popular Serbian Mastermind variant (Skočko or Jumpy) from the TV Show Slagalica

Architecture

• Model layer is in charge of storing and accessing data
• RoomDB + Dao + Entities were implemented on the top of SQLite
• GameRepository is an abstraction in charge of empowering the separation of concerns
• GameViewModel is the core of the app which interacts both with the UI and the Data layer
• GameActivity is as lightweight as possible
• GameFragment is in charge of binding data and xml and passing events to GameViewModel
• UI and Unit test cases were implemented to prove app behaves properly
• Skočko app adapts well to edge cases like and supports screen rotation

Potential Enhancements

• add statistics
• increase the No of tests
• add more error handling
• add a timer
• implement difficulty levels
• test on multiple devices (tested on Samsung A10 and Pixel 2)

• Kudos to Mañana for designing Skočko, Bear and Piggy icons!
• Kotlin and MVVM knowledge base: Codelabs
