Offline Single Player Modes
Tetris DS features several modes that utilze the original tetris format in different ways.

Standard
This is similar to the original Tetris with no special twists; You simply rotate the tetriminos and fit them into horizontal lines.


 * Marathon
 * After clearing certain amount of lines, the character animation on the top screen changes. Every horizontal line you clear counts as one line. Every 10 lines you clear moves you up to the next level. If you beat Level 20, you unlock the Endless mode, which lets you play forever. Every level is an etch faster.


 * Line Clear
 * Similar concept to Marathon; clear lines to make the character at the top move. The difference, however, is that you have a certain amount of lines to clear. You can set 2 things before the match; the Level and the height. Level changes how fast the blocks fall, while Height changes the amount of junk blocks that the game starts off with. The higher the both of those are, the more points you get.


 * Vs CPU
 * The title explains the purpose. It's simply a game of tetris against a computer simulated opponent. The speed of the computer is affected by levels. Levels range from 1 to 5, with 1 being the weakest and 5 being the strongest. In competetive Tetris, whoever reaches the top first loses. You gain the ability to send "New Blocks" to your opponent. New blocks are lines of gray tetris pieces missing one block (so the line doesn't clear). Clearing 2 lines sends 1 new block line, Clearing 3 lines sends 2 new block lines, and clearing 4 blokcs sends 4 new block lines. If you get "Back to Back TETRIS", then it will send 5 new block lines.
