When I tried to open the game a sign appears with a lock that says; "Content isn't available right now. When this appears it's usually because the owner only shared it with a small group of people, changed who can see it or it's been deleted"
It same with the desk top version and on Facebook. The only way I could even get to the forums was to google Viking Yoworld. Interesting is that the game appeared with no problem. I always log on thru the desktop and play off and on Facebook

Sorry it is working now
