This game could use an Undo button

Sometimes when the ad refreshes, it changes where the puzzle is on the screen and I hit the wrong square by mistake. Also when I try to submit and it says I got it wrong, I'd like to be able to back up a few steps.

Anyone else wish there was an Undo button?

I agree! An "undo" button would be a fabulous addition to the game.

Yes! I have wished for an Undo button many times. Often when I go wrong, I don't remember which boxes I need to uncheck, and so I just start over. With an Undo button, I could just back up a step or two.
