I’ve been playing this game every morning, along with several other Mobility games, as part of my “get my brain up and running” session. Until recently, that is.
     I’ve reached puzzle #1974, and have enjoyed the various themes made available for my choice.  Until they weren’t made available any more. The last 31 times I’ve completed a theme and should have had choice of a new theme, I was limited to choosing either “Places” or “1990’s.”
     In fact, the last 10 times, I wasn’t given a choice.  The windows said “Theme 1” and “Places.”  Tapping “Theme 1” got no response, so those last ten times I played “Places.”
    As a final frustration, now the theme never completes.  Every puzzle that comes up is “The Eiffel Tower in Paris.” Scout’s honor.
    I’ve finally given up.  All I play is the daily puzzle.
   I tell you sincerely that Word Search has been my favorite word puzzle until these bizarre things started occurring. I surely hope you can straighten this out.
    Oh, one more thing: I’ve intermittently had the black screen problem that other players have mentioned. Not lately, though. Just “The Eiffel Tower in Paris” over and over and over.........
