Thinking can be trained too
Much more than a pastime
Deductive reasoning
Form hypotheses, test them against the clues and rule out possibilities until only one remains.
Careful reading
A single word, such as “between”, “near” or “not”, can change everything. Every detail counts.
Spatial awareness
Orient, place and connect elements on a grid: rows, columns, directions and diagonals.
Persistence
Making mistakes is part of the process. Review your decisions, try another strategy and get closer to the solution.

What is Katadoku?
Katadoku comes from kata (型), a Japanese term related to form and patterns, with an ending that recalls classic Japanese logic games.
Katadoku brings together different logic and deduction games with one shared foundation: a 3×3 grid. Each game presents a different challenge, but you will always connect clues, rule out possibilities and find the solution.
9 positions. 1 solution.
