ABDEC – Decipher the Lost Language 🧠📘

This is not just a puzzle book—it’s an excavation of a forgotten system.

ABDEC from Letibus Design is a spiral-bound puzzle book that invites you to decipher the mysterious writing system of the strange little “Abb” creatures. Instead of teaching you the rules up front, the book asks you to discover them yourself through more than 70 deeply clever, page-transcending puzzles, hidden secrets, and rewarding breakthroughs.

📘 A Puzzle Book Like No Other

ABDEC is presented as a lost textbook, partially damaged and incomplete, forcing solvers to figure out how the writing system works entirely on their own. It’s a bold, rule-discovery experience built for curious minds and serious puzzle lovers.

🧩 70+ Mind-Bending Puzzles

Across 88 full-color pages, you’ll find more than 70 puzzles, plus hidden layers, secrets in plain sight, hints, explained rules, and solutions to support your journey.

✍️ Includes Transparent Plastic Sheet

The physical edition includes a transparent plastic sheet that can be placed over any page and written on with a dry-erase marker, opening up tactile and interactive ways to explore the puzzles without marking the book itself.
