Advent of Code in Rust: Winners and Highlights

Tatiana Parshutkina

Thank you to everyone who joined Advent of Code 2025 in Rust! It was inspiring to see many Rustaceans solving algorithmic puzzles, and celebrating the holiday coding season with the community.

Before the Advent began, Vitaly Bragilevsky published a blog post on how to use AI in Advent of Code challenge responsibly and effectively. This year’s AoC featured 12 puzzles, and from December 1–12, we celebrated by posting daily RustRover features in our RustRover Advent Calendar – a small gift for the community and a way to highlight tools that make your Rust experience even better.

And the winners are… 

We invited you to take on the AoC puzzles using Rust, join our leaderboards, and compete for top scores and random prizes. Now, it’s time to congratulate our 10 winners who stood out among all participants.

Let’s give a big round of applause to the top five Rust developers who dominated the combined leaderboards with impressive results out of 71 participants:

1. Duro – 2017 (for the second year in a row, as in 2024!)
2. JohnX4321 – 1996
3. MaRcR11 – 1961
4. Giacomo Stevanato – 1910
5. Agnibha Chakraborty – 1885

Additionally, here are five participants were randomly selected as prize winners:

• bragrseg – 576
• ViincentLim – 1585
• N. Adhikary – 813
• Gunter Schmidt – 435
• Saurav Kumar – 676

We reached out to the winners who had social media contact information listed on their GitHub profiles. If you didn’t include contact details, please reach out to rustrover-support@jetbrains.com, and we’ll be happy to send you your prize. Congratulations to all our winners and to everyone who took part!
