Solitaire Classic was originally developed from July 2016 with C++ and Madewithmarmalde middleware, however due that middleware going out of support - the team changed to C# and Unity and ported the game. Closed beta testing with the new architecture, the back end work, and soft-launch resting completed with the game going live in October 2017.
