I don't know what has happened, but Spider Solitaire (intermediate level) became easier to win. The longest streak I've ever had was 22 games until recently. I won 37 games in a row and then clicked the WRONG thing when I was going to return to the game instead of quit and end game. ARGH!!! I've won all the ones since then now and would have over 40 in a row if I hadn't done that. Many times I'll go back and undo all the way back to the beginning or to some other place. Then I'll keep trying various moves until either I win or give up. I was so on a roll with 100% until I over-clicked. I am so bummed. I will not reset and start over though. (sigh) I'll just carry on from here and see if I can top my previous streak.
Added later: I spoke too soon and screwed myself when I clicked the wrong part. The game has gotten harder again. :-(
