I've spent several years solo-developing an ad-free website with over 50 different solitaire/puzzle games:

https://inSolitaire.com

I've rewritten this project (almost) completely three times and now doing it for the fourth time, with tests and best practices.

I would be incredibly grateful for any feedback what I'm missing with it.

So far it has been great fun and I have learnt an incredible range of things!
