Daily Sodoku

when I try to play daily sodoku it appears to be frozen.  The numbers come up, but there are gift package images and a lot of other clutter over the top.  Can't play.  this has been going on for about a week.  Sometimes, if I leave the game and come back later it will work.  But that hasn't worked the last two days.  It caused me to loose a challenge last week because it froze and I couldn't finish by the deadline.
