(I created a facebook game, and wanted to upload it in scirra arcade, but it seems that it is not possible, you know any sites hosting games for free in HTML 5? Thank you.)
There are a bunch such as en.altervista.org. I'm working on Fii.com myself. One concern however is Facebook wants secure mode. Players need to uncheck the secure only setting in their account and I'm not sure yet if you can use the credits API unless you have a secure server. Have yet to find a free secure server. :(
Develop games in your browser. Powerful, performant & highly capable.
I use fav.cc and 000webhost.com
As Ianceal has said, Facebook requires you webpage have a SSL, and a trusted one too.
Thanks, I'll try here, if you can stand, but I think we can close here, thank you.
