Scoring

Most games award points to the player for completing various tasks. The earliest games awarded points only for dropping tetrominoes, and some even gave a penalty for leaving piece preview turned on.

After Tetris for Game Boy, most games adopted a scoring system designed to reward difficult clears by giving points for more lines cleared at once. Some systems also encouraged starting at higher difficulty.

Original Nintendo scoring system

This score was used in Nintendo's versions of Tetris for NES, for Game Boy, and for Super NES, as well as in Bullet Proof Software's versions beginning with the Famicom version.

Level	Points for 1 line	Points for 2 lines	Points for 3 lines	Points for 4 lines
0	40	100	300	1200
1	80	200	600	2400
2	120	300	900	3600
...
9	400	1000	3000	12000
n	40 * (n + 1)	100 * (n + 1)	300 * (n + 1)	1200 * (n + 1)

For each piece, the game also awards the number of points equal to the number of grid spaces that the player has continuously soft dropped the piece. Unlike the points for lines, this does not increase per level.

List of games

The following is a list of games that use this system, along with notes and differences:

• Tetris (BPS): Points are only totalled up after each level. Since the game only has hard drop, the score per piece is the number of rows covered by the hard drop (?).
• Tetris (Nintendo)
• Tetris (Game Boy)
• Tetris 2 + Bombliss: Awards 3 or 5 points if piece is soft dropped (research pending). Tetrises from level 55 onwards are affected by integer overflow and as a result score much less (e.g. lv. 55 Tetris scores 66000-65536 = 464 points).
• Super Tetris 2 + Bombliss
• Super Tetris 3
• Tetris X: Does not score dropping pieces.
• Tetris DX: Level multiplier stops increasing after level 20.
• SuperLite 1500 Series: The Tetris: Does not score dropping pieces. Awards a fixed 1,000,000 point bonus for a perfect clear.
• Tetris (Wonderswan Color): Base score assigned to level 1. Does not score dropping pieces. Awards a fixed 1,000,000 point bonus for a perfect clear.

The New Tetris

The New Tetris awards "lines": one for each line cleared, one extra line for clearing four lines with one I tetromino, and several lines for clearing parts of a 4x4 square. This does not increase as the game gets faster. Soft and firm drops do not give points; instead, they allow the player to place more tetrominoes (and clear more lines) in the three minute game.

Tetris Worlds

Each mode of Tetris Worlds has its own scoring system. As in The New Tetris, the unit of score in each mode is "lines"; 2-, 3-, and 4-line clears grant additional points in some modes.

Tetris Deluxe

Tetris Deluxe scoring system is similar to Tetris Worlds.

Tetris DS

Each mode of Tetris DS has its own scoring system. Most notably, the system used in Standard mode represents a fusion of the 1, 3, 5, 8 pattern used in several modes of Tetris Worlds with the section multiplier of the NES and Game Boy system.
