Here is a screen shot of a "ledge" problem. These "ledge" puzzles have given me real trouble in the past. I have spent 2 or 3 minutes trying to nudge a single piece off a ledge. In this puzzle, the pieces won't drop through cleanly in two of the six columns. They need to be moved around to drop correctly. For some reason trying to figure this out makes me see double and mutter unkind things.
