Brilliant app. I want to thank the Japanese developer for all your hard work and commitment to this fascinating technology. The Japanese abacus is a tool that helps the development of the mind to a supreme degree. I have seen kids in japanese junior high schools doing things so astounding, making super fast calculations of huge numbers. It is almost unbelievable. The Japanese abacus, or Sokoban, is my favorite tool for brain training. But is much more than that. It is an art form. I love it.
