Developed by Intelligent Systems, Panel de Pon DS is a DS installment in the puzzle title that's variously known as Tetris Attack, Pokemon Puzzle League and Pokemon Puzzle Challenge. The rules are different from Tetris, but the point is the same: eliminate tiles and make combos. The DS version adds a few elements to the mix, including the expected stylus-based controls. Just like Tetris, you'll be able to play against far off players thanks to included 4-player Wi-Fi support.
This game is also known as Panel de Pon DS in Japan.
