Letibus custom puzzles

This is a collection of custom puzzles which follow the rules and systems of various games made by Letibus Design. Be aware that these puzzles and their previews may spoil the mechanics of some of these games, which are best enjoyed playing them blind. These games include LOK, Abdec, Workworkwork and Herd.

SPOILERS AHEAD!

BABA BABA (Abdec)

Find the right, unique shapes for Y, O, U, such that the solution is unique. If the letter shapes you find give multiple solutions, then they're not the right shapes!

Language Barrier (Abdec/LOK)

Crossover chapter between Abdec and LOK. Figure out how their mechanics interact.

Letibus Advent Calendar 2025

People on the Letibus Discord server came together to craft an advent calendar of puzzles, often coming up with interesting crossover-puzzles and variants with new mechanics. The advent calendar is available for free here. I made the puzzles for days 8 (Abdec/WWW), 19 (Abdec) and 23 (Abdec x 2).

Blažizza (Abdec/LOK/WWW/Herd)

A discussion on the Letibus Discord server sparked the idea of a puzzle that would work under the various rulesets of the Letibus games. I initially intended this to work for Abdec, LOK and WWW, and with some fiddling it turned into a really nice Herd puzzle as well. This requires post-game knowledge for LOK.
