Hi there,

Thank you for your interest! Sorry for my late reply as I don't check here very often.

I received such requests before and I looked into it. Unfortunately, there's no easy way to convert these books into Kindle/SmartGo format. I have thought about PDF, but it may not be mobile-friendly.

I can't promise anything, but in ascending order of likelihood:

• Kindle is almost impossible. I tried their conversion tool and it doesn't handle the go diagrams correctly. The only way to make this work would be to convert the go diagrams into image files.
• SmartGo is feasible, but again it will require a complete redesign of the books and involve a lot of extra work.
• PDF is the most likely. I have yet to find a good platform.

I appreciate your message and your encouragement means a lot to me.

Best, Ruoshi
