Simple Chat Bot (Kotlin)
- 4.1
- 7 hr
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!

Simple Tic-Tac-Toe (Kotlin)
- 4.3
- 12 hr
- Best rating
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)
- 4.2
- 11 hr
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.

Cinema Room Manager (Kotlin)
- 4.2
- 12 hr
Cinema has been a part of the entertainment industry for a long time: a good movie is a way to escape reality and live through a variety of emotions. The best cinema experience you can get is probably in a cinema theatre. In this project, you will create an application that helps manage a cinema theatre: sell tickets, check available seats, see sales statistics, and more.

Unit Converter
- 4.2
- 14 hr
When you travel, everything changes: people, languages, time zones, and even units. It may be difficult to read the temperature in Fahrenheit when you’ve always used Celsius, or to measure yourself in kilos if you’ve only used pounds. It’s no easy matter, though a nice unit converter could certainly help! In this project, you will write a converter that handles distance, weight, and temperature units – all the traveller’s essentials.
Chuck Norris Cipher Encoder (Kotlin)
- 4.1
- 13 hr
Secret agents use encryption all the time. You know that everything can be encrypted as different characters. What about encryption that uses only one character and space? This method has a name — the Chuck Norris cipher. In this project, you will create a program that can encrypt any text into a sequence of zeros and spaces and decrypt this sequence into text.
