I just reload the page and when it stops again without reaching the 100% and opening my game, I just reload it again.Reload your game until it finally opens.If this doesn`t solve it, you need to close your browser, clear the cache and load it again.And if it is still not loading, try to reboot your computer.
They stop at a certain percentage and do not continue loading it.What you can do is to reload your browser.That is what I do when my Candy Crush game stops loading. There are times when the games in Facebook are not loading properly.
