Sudoku is a popular logic-based game number placement game that appears in many daily newspapers around the world. Working on number based math and logic games may help boost your brain power – or at least keep it fresh. Think of it as mental exercise. For most people however, they simply like it. I’ve met people who “hate” mathematics, yet gladly fill out a sudoku or related puzzle to relax.

My former colleague Alejandro Erickson has created a wonderful new book of puzzles, a logic-game that focuses on geometric reasoning, rather than number reasoning like sudoku. It’s called Tomoku. In the video below, Alejandro demonstrates how to solve tomoku tatami puzzle from his book “Tomoku! 80 Challenging Tatami Puzzles”

You can give the game a try online on the Tomoku puzzle website
