Puzzle League DS - Beating Level 10+Hard CPU

In my opinion this (stage 10+hard setting) is the strongest Panel de Pon/Tetris Attack/Puzzle Leage DS AI out there. It's extremly quick and does very nice combos. However, sometimes it seems like the computer can't decide which panels it wants to clear first. It also has a little trouble with the instant clearing garbage blocks that are transforming. Nevertheless it provides a bigger challenge than Pokémon Puzzle League's and Tetris Attack's AIs. Note: The Level combined with the stage you choose sets the CPU's playing strength, so basically there are 30 difficulty levels, beginner on stage 1 being the easiest and hard on stage 10 the hardest.
