Many free dominoes games.
More and more games will be added soon.
I guess this is the first attempt to program many dominoes games. I have been in contact with the admin of the Facebook page for a while. I sent him my suggestions. If you have any suggestions, plz don't hesitate to send them. https://www.facebook.com/onlinedominogames
Dominoes rules are available. They are based on pagat, Wikipedia and dominoes websites
