Livestreams

Starting December 1, we’ll be holding livestreams every day at 5:00 pm UTC to discuss the puzzle of the day, giving you 12 hours to solve the puzzle before we go through it together. We’ll be joined by guests from the Kotlin team and the community to discuss possible approaches to the problems. It’s a great way to tackle the challenges together and learn some cool Kotlin tricks!

Community

Join the discussion in the Advent of Code channel on the Kotlinlang Slack, and share tips and tricks with other participants. Each day we’ll post a new thread where you can share your puzzle solutions. The most active community members will get some neat rewards!

Template

Make the most of our GitHub template, which is designed to streamline the structure of your solutions. This repository template is specifically for use with Kotlin, and it offers a solid foundation for your solutions, allowing you to get set up quickly so you can dive right into the problems.

To create a new project with this template, simply log in to your GitHub account, follow the link below, and click the green Use this template button. Please do not fork it!

Use the template

The template below is a fork of the main Advent of Code Kotlin Template repository that uses the Amper tool for project configuration, recently introduced by JetBrains. With this version, we swapped the standard Gradle build configuration with the module.yaml Amper file.

Use the Amper template
