Chiryoku = Intellectual Power.

Compared to the West, people in Japan live longer, healthier lives and at the heart of their culture – and part of their daily routine – are brain-training puzzles.

The square-box puzzles here, familiar to millions in Japan, are a workout for your mind.

Test and strengthen your mental agility, concentration, numerical skills, powers of reasoning, observation and creative thinking.

Enjoy working through puzzles that will take you from total beginner to master mind and help keep your brain healthy for years to come.
