Tetris Online (Japan) is an official online Tetris game for Microsoft Windows 2000/XP/Vista.

Gameplay

• ARE, IRS and IHS are not present.
• The Random Generator is used for piece distribution.
• Line clear delay is minimal to non-existent depending on the upgrade level.

T-spin

• T-spin recognition is 3-corner T.
• A T-spin Single which uses a wall kick is known as a T-spin Mini and is less powerful than a normal T-spin Single (see below). A T-spin Double/Triple with a kick is still counted as a T-spin Double/Triple.

Back To Back

• A Tetris or T-spin line clear is considered Back to Back (B2B/BtB) if the previous line clear was either a Tetris or T-spin.

REN

• REN is the Japanese term for combo.
• Each consecutive line clear increases REN by 1 regardless of the type of line clear (doubles/triples/tetrises only add 1 to the counter).
• The REN counter is displayed for REN 1 or higher. The first line clear can be thought of as REN 0, and thus is not displayed.

Single Player

Single player is only available to Premium users. It consists of the following four modes.

Time Attack

This is the well known 40-lines time attack mode, sometimes referred to as Tetris Sprint or 40 lines.

Challenge

• The aim of Challenge is to maximize your score before the timer runs out.
• Players begin the game at Level 1 with 2 minutes of time available.
• There are 30 levels in total.
• To clear a level, the player must bring the goal down to 0.
• The goal of each level is equal to 5 times the level.
• Completion of each level adds 30 seconds to the timer.
• Overclearing does not affect the goal of the next level.

Line Clear	Goal Reduction
Single	1
Double	3
Triple	5
Tetris	8
Tetris (B2B)	12
T-spin Mini	6
T-spin Mini (B2B)	9
T-spin Single	8
T-spin Single (B2B)	12
T-spin Double	12
T-spin Double (B2B)	18
T-spin Triple	16
T-spin Triple (B2B)	24

• A B2B line clear reduces the goal by 1.5 times more than its normal counterpart.
• REN reduces the goal by the same amount as the garbage it sends in multiplayer (see below)

Marathon

• The aim is to maximize your score before the game ends.
• There are 20 levels in total, the goal of each level is 10 lines.
• Line clears carry over to the next level.
• All line clears reduce the goal by the amount of lines cleared only.
• The maximum amount of lines clearable is 203 lines.

Hori Tetris

• The aim is to dig through a field of rising garbage.
• Four difficulty levels exist:
  • Easy - 100 lines
  • Normal - 200 lines
  • Difficult - 400 lines
  • Very Difficult - 1000 lines

Multi Player

Multi Player consists of the following classes/rooms:

Class	Free for All	Team Play	Maps	AI	Miscellaneous
Specials	Yes	Yes	Yes	No	Special items available
Beginner	Yes	Yes	Yes	Yes	15 LPM or under only
Intermediate	Yes	Yes	Yes	Yes
Expert	Yes	Yes	Yes	Yes	20G
1v1	No	No	No	No	Ratings, 'King of the Hill' format

• The maximum room size is 6. Premium users may create password-protected rooms.
• Teams must be the same size before a team match can start.
• After topping out, a player may choose to practice while waiting. The practice session continues until the current match ends.
• In a 1v1 game room, the winner stays in the round and the loser joins the end of the queue of spectators.
• TP earned after every match is calculated as follows:

TP = (players placed below you + 1) x (5 if premium, 1 otherwise) + (# of KOs)

Garbage Distribution

• In a free for all match, a target cursor that randomly switches between players determines to whom your lines are sent.
• Unlike other Tetris Guideline games, the change of garbage holes is not random. Each attack always sends garbage with the holes in the same column. However, the next attack will have a 100% chance of change in the column of the garbage hole.
• Additional line sends from B2B and REN are grouped with the corresponding line clear attack.

Possible garbage fields

1. Tetris, Tetris (B2B)

2. Single, Triple, Single, Tetris, T-spin Single (REN 4)

Training

Training is only available to Premium users. Training mode involves battling against the AI in a 1v1 match. There are 24 levels consisting of 3 stages each:

• Tetris
• REN
• T-spin
