The New Tetris for N64 was developed by H2O and published by Nintendo. Like Tetrisphere before it, The New Tetris features a soundtrack by Neil Voss.

It has lock delay, soft and firm drop, 4×4 squares, hold piece (though not IHS), three next pieces, ghost piece (TLS), and milder wall kick than SRS (notably, T-spin triples don't work but lock delay is still abusable on no-garbage play). The speed never gets anywhere near 20G. [oh? roughly where does it top out?] Colors of some tetrominoes differ from those of the Tetris Guideline: L is magenta, T is yellow, and O is light gray.

Top-out condition is the same as in Atari's Tetяis and the "push" mode of Nintendo's Tetris DS: the game ends when one block is placed above the playfield's top row.

The New Tetris defines twists (known in the manual as "spin moves") differently from the "T-spin" rule used in Tetris Worlds, Tetris DS, and other games that use SRS. In this game, a twist occurs when a tetromino locks in a position such that it cannot move left, right, or up without rotating.

[edit] Tetromino behavior

ARE: ca. 500 ms
Randomizer: Preliminary data suggests a 63-piece bag
Entry position: rows 21-22, centered, JLSTZ rounded to the right
Lock delay: ca. 500 ms, step reset, no manual lock
DAS: ca. 10 frames, repeating 5 frames
Up: Firm drop, not locking
Down: Soft drop, not locking
Top out: tetromino locks with a block in row 21

The New Tetris: Rotations in free space. Top row: I, O. Next rows: J, L, S, T, Z.

The rotation system of The New Tetris is a predecessor to SRS, with somewhat flexible wall kicks and floor kicks. But surprisingly for a game co-developed by BPS, its handling of J, L, S, and Z in free space is more like Atari Games' arcade game and its unlicensed NES port than like BPS's previous games.

Wall kick is yet to be fully described.

[edit] Squares

Main article: Square Platforming

A 4x4 block square made out of four tetrominoes becomes a monolithic square of the same size.

A square is entirely within the playfield.
If things are projecting out of a 4x4 block region, it is not a square.
If it has a hole in it, it is not a square.
If it contains blocks that form part of a tetromino or square that was partially removed, it is not a square.

Monosquare: A 4x4 block square made out of four identical tetrominoes.
Multisquare: Any other 4x4 block square made out of four tetrominoes.

[edit] Details

If a tetromino forms two overlapping squares at once, the gold wins over silver, the top wins over the bottom, and the left wins over the right. It is not known whether the top-right wins over the bottom-left.

The following diagrams use The New Tetris colors, which are not the same as the later Tetris Guideline colors:
