Make a list and check it twice because Advent of Code season is almost here!

We can’t wait for December 1, when the first of the 25 holiday-themed puzzles unlocks on adventofcode.com. 

For the second year in a row, JetBrains will be sponsoring Advent of Code in 2022. Many of our colleagues will solve these fun algorithmic problems every day. We invite you to join us in participating in Advent of Code in Kotlin this year!

It’s a great way to practice your problem-solving, keep your Kotlin skills sharp, compete, and learn from the fantastic community surrounding the event. And it’s a wonderful way to get your hands on some exclusive Kotlin prizes! 🎁

Livestreams

This year, we have livestreams planned every day at 5:00 pm UTC, during which we’ll discuss the puzzle of the day, giving you 12 hours to solve the puzzle beforehand. Together, we’ll walk through the problem statement, discuss possible approaches to solving the task, and chat with some fun guests from the Kotlin team, Google, and the community. Subscribe to our YouTube channel to stay tuned!

While we of course appreciate everyone with a competitive spirit, we don’t want to rush you. You don’t have to be the fastest or complete every challenge to win a prize. We want to make sure you experience the beauty of solving holiday puzzles in idiomatic Kotlin.
