UCit’s Advent Calendar 2025

Throughout December, UCit hosted a special kind of Advent Calendar. 
Each day, a new challenge invited our community to play, think, imagine and interact around HPC, technology and innovation.

From riddles and word games to creative challenges, equations and true-or-false statements, the variety of formats helped create a fun and engaging experience while staying true to our technical world.
 This Advent Calendar was also an opportunity to collaborate with several partners, whom we sincerely thank for their ideas, involvement and creativity.

Beyond the winners and the prizes, this Advent Calendar was above all a shared moment with our community. Your participation, comments and answers brought each challenge to life and played a key role in the success of this edition.

Thank you to everyone who took part throughout December.
 See you next year… for another edition full of surprises.
