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.
