Join Advent of Code with Axis!
November 11, 2025
Sign up and join ‘Advent of Code’* with Axis Leaderboard, a yearly advent calendar of small programming puzzles. Use your skills to solve puzzles that range from the very simple, to some real thinkers, using any coding language you choose.
There will be 12 days of puzzles to solve, and every day will have two stars to collect. The puzzles will become available every morning at 06:00 Swedish time (UTC+01:00).
Signing up to the Advent of Code leaderboard with Axis is a great way to practice problems, share experiences, learn from each other, and grow your knowledge.
