https://FreeSolitaire.win brings around $500/mo (advertising revenue).

I started making this PWA in 2016 and I’ve been slowly adding to it over time. I intend it to stay minimal & lightweight. No framework, etc.

Fun fact: because it is so lightweight, it was included in the Moya app (https://play.google.com/store/apps/details?id=nu.bi.moya), a popular messaging app in South Africa that is “data-free” for users (it does reverse-billing). Now half the players are South Africans!

Feedback is welcome ;-)
