A puzzle book by Blaž Urban Gracar

Discover a vast unknown world and learn its cryptic language

through more than 90 word-search puzzles!


LOK is a book of mind-bending word-search puzzles.

The goal of each puzzle is to find Lok ​keywords and use their special effects to black out all cells in a grid. On top of that, you must also figure out most of the rules by yourself, deducing them from the carefully crafted sequence of more than 90 puzzles, contained in the main storyline, 2 expansions and many off-page enigmas. The result is a deep and rewarding experience with surprising twists and insights.


LOK is available as a physical book. It is spiral-bound and it includes a transparent sheet that can be placed over any page and drawn on with a dry erase marker. Solving puzzles on paper is the way that LOK is meant to be played. Buy it here.


PDF available in English and Japanese

LOK is also available as a free PDF for everyone to enjoy. You can draw over the PDF with any drawing tool software - a good free drawing tool is Drawboard. You can also download the Japanese edition with the translation by CompetorDownload the PDF from the LOK's Itch.io page.

"... While the market is currently flooded with all kinds of derivative logic books filled with computer generated Sudokus and Kakuros, LOK differentiates itself as an ingenious passion project of someone who simply wants to contribute to the world of puzzling."

Playthrough of the first 5 puzzles of the book:


"... So I really enjoyed this ... I liked the way it introduces the rules, because it doesn't tell you strictly the rules, but it just shows you a puzzle and 'Oh, there's a new word! ... This puzzle is solvable, so what does the new word do? ... This word must do something that blacks out these squares,' and so you kind of figure out what it does, which I think is really cool."
