Abdec is a forgotten textbook about the writing system of the weird and elusive "Abb" creatures. Their typography resembles devilishly difficult packing puzzles. Due to a fire accident that burnt important pages in the book - the last remaining Abdec book in the world, which was also scanned for this reissue - players need to figure out how the Abdec writing system works completely on their own.
From the creator of the critically acclaimed puzzle book LOK, Abdec continues with the same design philosophy of making rules a part of the puzzle, but takes it to the extreme. Meant for thinky connoisseurs and those who want to explore ruleless puzzlescapes beyond LOK, it offers a challenging, but deeply rewarding solving experience.
Abdec is available as a spiral-bound physical book, printed in full colour. It includes a transparent sheet that can be placed over any page and drawn on with a dry erase marker. On 88 pages you will find more than 70 puzzles, multiple awe-inspiring secrets hidden in plain sight, plus hints, explained rules and solutions.
