I've spent several years developing an ad-free website with over 50 different solitaire/puzzle games:
I am currently rewriting the engine for the fourth time and plan to add 400 games to the platform next year, as well as social features such as daily challenges, awards and leaderboards.
My main goal, however, is to make this project the largest collection of free modern solitaire games available for mobile devices and desktop computers.
So far, the project has been incredibly exciting, and I've learned so much!
This is awesome!
