Tetris Kiwamemichi (テトリス極道) is a Tetris game for the Sega Naomi arcade platform and the PlayStation 2.

Gameplay

Tetris Kiwamemichi features the standard Guideline ruleset for gameplay. However, there is also a 750ms delay between a piece spawning and said piece speeding up to the current gravity value, thus making it easier to maneuver a tetromino at 20G.

Two level systems are used in-game:

• Arcade – the level increases every piece drop or line clear, similar to the Grand Master series. This is the sole system in the arcade version, and is selectable in the PlayStation 2 version.
• Home – the level increases every 10 lines cleared. This is the default system in the PlayStation 2 version.

Modes

Tetris

Endless Marathon mode. If using the Home level system, the starting level is selectable; the level cap is 20 (200 lines). The game ends when the player tops out.

Scoring

Scoring for the Tetris mode is as follows:
(Base score) x (Level before clear + Lines cleared + 2) x (Back-to-Back bonus)
where:

• The Back-to-Back bonus is 1.5x for back-to-back Tetrises, and 1x in all other cases
• The base score is identical to the Nintendo NES Tetris base scores:

Lines cleared	Base score
1	40
2	100
3	300
4	1200

In all cases, the maximum score per clear is capped at 100,000 points. This means there is a maximum score per line, and the optimal line clear changes as time goes on (as seen in this spreadsheet.)

On the PS2 version, all scoring is reduced to 1/10th of its arcade equivalent, with the cap still remaining at 100,000 points. This means that Tetrises are optimal for far longer than in the arcade version.

Chain Colors

Any blocks of the same color as the same piece used to clear a line will collapse with cascade gravity. Only available in the arcade version.

Target

The player must clear a set of garbage lines with blue gems in them, similar to Flash Point.

Level Star

The player must clear a set number of lines within a certain time period. The line goal increases per level.

Line Break / Hotline

The player must clear lines inside a set of highlighted rows to complete a stage.

Battle Mode

Standard versus gameplay with garbage line attack system. The position of the garbage holes on the playfield change for every line(s) sent, and all holes are aligned to a single column. Items are also available in-game.

Co-Op Play

Two players (or up to four in the PlayStation 2 version) clear lines within a shared 20 × 20 playfield. Each player can freely move their piece across the entire width of the playfield.
