Apply your knowledge by building a project

If you're just starting
  • Simple Tic-Tac-Toe (Kotlin)

    • Best to start

    Everybody remembers this paper-and-pencil game from childhood: Tic-Tac-Toe, also known as Noughts and crosses or Xs and Os. A single mistake usually costs you the game, but thankfully it is simple enough that most players discover the best strategy quickly. Let’s program Tic-Tac-Toe and get playing!

  • Coffee Machine (Kotlin)

    What can be better than a cup of coffee during a break? A coffee that you don’t have to make yourself. It’s enough to press a couple of buttons on the machine and you get a cup of energy; but first, we should teach the machine how to do it. In this project, you will work on programming a coffee machine simulator. The machine works with typical products: coffee, milk, sugar, and plastic cups; if it runs out of something, it shows a notification. You can get three types of coffee: espresso, cappuccino, and latte. Since nothing’s for free, it also collects the money.

  • Zookeeper (Kotlin)

    This short code challenge can help the local zoo look after its denizens. You will create a tool for monitoring animals and their status.

  • My First Project with Kotlin

    • Fastest to complete

    Imagine that you're the owner of a new small corner shop. You are doing well and want to determine how much you earned in the first month. Create a simple tool that will calculate your net income. Upon completing this project, you can use this tool for your own accounting needs.

  • Simple Chat Bot (Kotlin)

    Here, at the beginning of your programmer’s path, creating a simple console chat bot will do wonders to guide you through the basics of coding. During this journey you will also play some word and number games that you are going to implement all on your own. Pack up and let’s hit the road, my friend!
