Tetris DS

Standard mode
Standard Tetris.

This mode supports single player, 2 to 10 player "Ni-Fi" (proprietary local Wi-Fi) with one DS Game Card, and 2 or 4 players in Nintendo Wi-Fi Connection, although many people have found it impossible to get a 4-player game going without it failing with an 86420 error.

The playfield in single player standard is at least 23 cells tall. Verification: Lay an I tetromino on its short end with only visible block, then clear some lines. All four blocks of the I will remain.

Scoring tables

 * The following is based on original research and could use verification.


 * Level = floor(number of lines before line clear / 10)
 * Soft drop: 1 point per cell
 * Hard drop: 2 points per cell
 * Line clears:
 * single: Level * 100
 * double: Level * 300
 * triple: Level * 500
 * tetris: Level * 800
 * T-spin no lines (kick): Level * 100
 * T-spin no lines (no kick): Level * 400
 * T-spin single (kick): Level * 200
 * T-spin single (no kick): Level * 800
 * T-spin double: Level * 1200
 * T-spin triple: Level * 1600
 * back to back (tetris or t-spin 1-3 lines): * 3/2
 * for example, back to back tetris: Level * 1200

Push mode
Theme: Donkey Kong Influences: Original PC prototype of 2-player Tetris Playfield: 10w x 38h

Push mode starts with two blocks near the center of a playfield roughly twice as tall as the standard playfield. Tetrominoes drop in opposite directions for the two players. Dropping a tetromino past the mass of blocks causes it to disappear. When a player completes more than one line at once, all blocks in the playfield move a number of lines toward the other player's side. (Unlike in Standard mode, T-spins and Back to Backs do not count extra.) Once one block is placed or pushed off a player's end of the playfield, the player loses.

In push mode, it is possible for a game to be drawn by clearing all blocks from the playfield, although the program is incapable of recognizing a drawn game, and the first player to disconnect will lose.

This mode supports single player, 2-player Ni-Fi, and Nintendo Wi-Fi Connection.

Mission mode
Theme: The Legend of Zelda

Missions include Conspicuous by their absence are any missions involving T-spins.
 * clear at least 2, 3, or 4 lines with a single tetromino
 * clear 2 or 3 lines with any tetromino other than I
 * clear 1 or 2 lines with a specified tetromino
 * clear 5 lines where only one or two specified tetrominoes are dealt
 * clear 5 lines under increased drop speed
 * clear 3, 4, or 5 lines using a single type of tetromino
 * clear 2 or 3 lines separated by one or two gap rows, otherwise known as a hurdle
 * clear a line at a given height on the playfield
 * clear a line without rotating tetrominoes, where tetrominoes spawn in random orientations
 * clear four lines at a time twice in a row

Modes:
 * Marathon: complete each mission in the time available or have 5 garbage lines added.
 * Time Trial: choose dificulties 1 through 5, and complete the set of 10 missions, given in randomized order, as quickly as possible.

Catch mode
Theme: Metroid Influences: Klustar (GBC) and Katamari Damacy (PS2)

This mode has been compared to inverse Tetris. Player moves and rotates a clump of blocks to catch the falling tetrominoes and avoid the falling metroids. Forming a 4x4 square of blocks without gaps (not necessarily of whole tetrominoes, unlike The New Tetris and Square Tetris mode of Tetris Worlds) will cause the tetrominoes to light up and explode 10 seconds later. The player can add overlapping 4x4 squares to this critical mass within these 10 seconds, or the player can trigger this explosion early. Hitting a falling metroid with the clump, hitting a falling tetromino with the clump while it is rotating, or letting a tetromino hit the bottom, will cause the player to lose health. When the health bar is depleted, the game is over.

Puzzle mode
Theme: Yoshi's Cookie

Three, four, or five tetrominoes are displayed in the touch screen. The player chooses a tetromino and orientation using either the stylus or the +Control Pad and A Button, and if it would clear one or more line, it is dropped into the puzzle in the top screen. (Sliding and in-place spins are not possible.) Goal is to clear all lines.

Alleged design defect: For L, J, and T, which have four distinct orientations, the default orientation is assigned to Left on the +Control Pad, not Up as would be expected.

Touch mode
Theme: Balloon Fight Influence: Klotski; Puzznic

This mode has two modes, one where the blocks drop, and you try to maximize points by shifting and (in levels 1, 2, and 3) rotating tetrominoes and partial tetrominoes to form lines. The other mode "Puzzle" mode, has you attempting to achieve various goals by moving blocks into a certain position to achieve certain numbers of combos, line clears, clear ll blocks.
