What is LOK?

Lok are a fresh new kind of living beings that spawned in the middle of a vast, incomprehensible world. Help them understand their surroundings and guide them towards expansion of their civilisation.

This book consists of hand-crafted puzzles to solve. Besides solving puzzles, you are also required to figure out most of the rules by yourself.

The goal of each puzzle is to black out all cells in a grid. You do this by finding keywords and using their effects.
