Philosophy that cannot be played is boring!

Logos

Logos is a one-of-a-kind system that brings together:

A bold, innovative take on the classic Sudoku Puzzle.
A fresh author’s interpretation of the ancient philosophical oracle, the Book of Changes.
An original deck of Logos Associative Cards.

Because it adapts to you. Depending on your mood, you can:

Challenge yourself and sharpen your strategic thinking, logic, and focus by playing the thrilling Sudoku 42 – either with a friend or against the program.
Slow down, unwind, and meditate with Logos Sudoku Solitaire. Each layout reveals a chapter from the Book of Changes and an associative Logos card to guide your reflection.
Draw a Logos card in the Card Bot, explore what it evoked for other players, and share your own insights.
Open a theme in the Notebook Bot and record your reflections. The associative Logos cards will help you uncover layers of your own unconscious.

Choose your favorite card and order it as a T-shirt, mug, or puzzle from the Logos Shop.
