Compatible in the original DS and DS Lite only, does not work in the 3DS, 2DS or DSi. Tetris DS THQ version. Features 6 complete game modes. Classic Tetris, Cascade Tetris, Hotline Tetris, Tetris Draw, Tetris Warning and Tetris Trash. Tested and saving works. Excellent condition. Game cartridge only, includes a small protective cart case Classic Tetris allows you to hold a piece with the X button and hard-drop with the usual Up, but also maps L and R to hard-drop, which is sure to throw off any veterans of Nintendo's Tetris DS. Cascade Tetris is the same as Cascade from Tetris Worlds, and is basically just Tetris with gravity. Pieces are treated as one solid block that can be broken apart by line clears. Individual pieces will freely fall, instead of being suspended in midair as in more normal Tetris variants Hotline Tetris continues the Tetris Worlds theme, being largely the same as the other games from that series. Goal points are scored when clearing lines only on the marked lines, with more points for the higher ones. Tetris Draw requires you to draw pieces on the bottom screen. After they're drawn, they will float above the playfield. You can drop them with L or R, and simply start drawing again to cancel. Garbage constantly rises so you can't afford to take your time. Tetris Warning is Tetris except played in a huge well, 48 blocks tall. Pieces will spawn on the top screen at preset intervals, with random positions and orientations. You can only control the bottom-most active piece, and control switches to the next lowest one after it's been placed. Tetris Trash features two playfields. The top playfield is your standard Tetris, just limited to an incredibly small 10x10 square. Placing any block outside of the playfield is an immediate loss. The bottom playfield comes into play when you push Y. The top playfield will rotate 180 degrees, and the pieces inside will fall down the screen into the lower playfield. Pieces, on the lower field only, are affected by gravity (or cascade rules).
