Block Hints $1 has 22,850 Rush Hour puzzles. I emailed Joel (author of Blocked 100 levels) about using this free generator back in September 2008 I believe to do so but he kept it simple. Don't blame him. But for hardcore Rush Hour fans this is pure heaven. Graphics look dope and decent I just hope controls work well. Parking Lot has 360 levels. Pretty sure used the free Rush Hour Puzzle Solver to generate puzzles. More power to him as I've been waiting for someone to do this.
