Tetris Friends

Tetris Friends is a Tetris game available on its own website. Registered users are able to compare their scores with their friends and with the entire community. It is the only official Flash implementation of Tetris made by the Tetris company itself. Tetris Friends has over a million registered users. Until 2012, there was also a Facebook version.

You must be 13 to be eligible to play Tetris Friends (birth date required (if found to be under 13, game is blocked until your 13th birthday)). You will also need to provide your gender and region (required!) so that TTC can customize your gameplay.

Below is a table for Normal Mode and Expert Mode (Numbers in bold are different than E+ Mode):

Modes
There are 11 game modes available. The game features 6 single player modes and 5 multiplayer modes.

Marathon
A standard marathon mode with 15 levels. The game ends once level fifteen is completed, and the score is recorded and added to the high score list if the user has a registered account.

In both versions, this mode always starts from level 1.

The website version uses the variable goal system (5 for level 1, 10 for level 2, 15 for level 3, 20 for level 4, etc.), but lines is not true lines. It scores in the same way as Tetris Worlds.

The Facebook version has a different goal system (5 for levels 1-5, 10 for levels 6-10, and 15 for levels 11-15).

Scoring Strategy
Tetris Friends has a goal system where the way to get to the next level is to clear a certain number of goal lines that increases as the levels do. The optimal way to acheive a high score is using the Single-single combo strategy:

Sprint
Clear 40 lines as fast as possible. Level is not selectable and fixed to 1. This is an excellent mode to practice in because it is the only 1P mode which has the same game mechanics as Arena with Expert Mode. The time required to clear all the lines is recorded as the score. When you reach the top of the screen, you lose the game, and the score will not be recorded.

Sprint 5P (Sprint 4P in Facebook)
In Sprint 5P, the player is playing against four opponents in Sprint mode. Opponents are just previously recorded games that were played by other people, or even the players themselves, based on your current rank. This mode uses slower gravity than normal Sprint and therefore has a heavy time penalty for all twists.

Arena
Arena is the only live multiplayer mode. This mode features realtime multiplayer for 2-6 players. There are currently 20 player ranks and 4 player classes. The player is awarded points based on how well they do, how many lines of garbage they sent, and how many people they KO'd.

Ultra
2 minute ultra mode. The goal is to score as many points as possibly you can within 2 minutes. In the Facebook version, the music is selectable from 5 songs. Only "Midnite" music is available in the website version. This mode was formerly known as Tetris Solo, additionally, a 3 minute mode was also available. Level is not selectable and fixed to 1. Scores are not recorded if a player tops out.

T-Spin with wall kick is allowed even if it is played in Facebook version. However there are some graphical glitches. If you perform TST, only the score marker (the floating "+1600" text) will be displayed.

Battle 2P
In Battle 2P, the player plays against a randomly selected opponent. As in Sprint 5P mode, opponents are just the previously recorded play. The goal is to KO the opponent three times by forcing them to reach the top of the screen. Garbage lines don't have holes. They can be removed by attacking the opponent. There is a two-minute time limit. If no one has won by the end of two minutes, the player that has been KO'd the most times loses. If both have the same number of KO's, then the player that sent the most lines of garbage to the other player is the winner.

Battle 6P
In this game, you play against five other opponents. There is a target that constantly alternates between the other five players. When garbage is sent by the player, the person that the target is current pointing at is the one that receives the garbage. KO's are awarded to the person that last sent garbage to the KO'd player, so timing of attacks is important in earning KO's. The last player standing after two minutes is the winner. If multiple people have not lost, then the player with the greatest difference in KO's to loses is the winner. If that is tied, then number of lines of garbage sent is the tie-breaker, as in Battle 2P. By doing well, the players can earn stars, which promotes them to new ranks. Doing poorly will cause players to lose stars. You can select a map. (the initial block patterns, as seen in TOJ)

Game Tunings
Game fine tuning is very expensive to be bought with tokens, but cheap with rubies. Very important, after purchasing these upgrades you must customize them on your profile page under "My Tetris Style" > Advanced for them to have actual effect. Two big upgrades are DAS and ARR. There are also two other upgrades which were designed to neutralize the effect of the 0.5 second line clear delay: IHS and IRS. It is recommended first to get 5 ARR, then at least 3 DAS, then IRS and IHS.


 * DAS - Delayed Auto Shift: controls how long it takes for a piece to start sliding once you hold left or right. The maximum (fifth) value may not be recommendable without
