This is my best and favorite 9th key pattern. It's fast, quite stable, and it's easy to notice if you are off pattern well before a collision. It saves the stairsteps above the monster box and at the bottom till late in the pattern (spots where it's easy to make a tiny mistake). There is one apparent close call with Blinky where he goes against his usual behavior and turns away when he is right on Pac-Man's tail, but the coolest part has you charging Pinky right before a reverse, "scaring" him off into the tunnel as he Bounces into Inky sending him in the other direction, you have to see it it's pretty cool. I recently modified the ending to an even safer solution. It clears the board in 45 seconds.
