Letibus Advent Calendar 2025

~ Knowledge of Letibus Design puzzle games is required to solve the puzzles of this advent calendar ~

In November 2025, on the "Letibus Club" Discord channel, the user Plushloler had an idea of making an advent calendar of puzzles using the various puzzle systems introduced by the Letibus Design games ("LOK", "Abdec", "Workworkwork" and "Herd"). With the user Nitrrose as the driving force behind the organisation, lots of people responded to the call for submissions and after an intense month of preparation and playtesting, the Letibus Advent Calendar was ready. Originally posted on social networks from December 1st to December 25th, these puzzles are now compiled in a PDF and a zip with JPGs for everybody to revisit.

I want to sincerely thank the "Letibus Club" community for their inspirations, work and commitment. I never dreamed that the silly puzzles that I make in my free time would blossom through the minds of so many talented people into this beautiful batch of mind-blowing challenges. - Blaž
