Tetris Friends is an online Tetris game developed by Tetris Online, Inc. It is available on its website and previously on Facebook.[1] 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.[2][3] Tetris Friends has over a million registered users.[4]

Tetris Friends features 6 single player modes and 5 multiplayer modes. Coins are earned for playing any of the games modes. The coins can be used to unlock new skins and Tetrimino styles. The version available on Facebook only has 4 of the modes available on the official website and it has no coin system, but it does feature a special mode available only on Facebook.

All game modes except Tetris 1989 and N-Blox use the SRS rotational system, feature the hold function which allows players to save a block for future use, and have a four Tetrimino preview that allows players to see the next few upcoming blocks.

Game Modes[edit]

Single Player[edit]


In Marathon Mode, players have to clear a specified number of lines while trying to score as many points as possible. Clearing multiple lines with one piece is worth more than the actual number cleared. For instance, clearing a single line is worth only one, while clearing four lines with a single piece is worth eight lines. Once the goal has been reached, the level and speed increases and a new, higher goal is set. There are fifteen levels in total. 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.


Sprint Mode requires players to clear forty lines as quickly as possible. The time required to clear all the lines is recorded as the score. The speed is automatically set to the lowest setting.


Ultra Mode challenges players to score as many points as possible in two minutes. Clearing multiple lines with a single piece scores more points. Special moves called t-spins are also worth extra points. If the player loses by reaching the top, the score does not count and is not recorded in the high score list.


Survival Mode is similar to Marathon Mode. Players have to clear ten lines per level while scoring as many points as possible. Every line cleared is worth only one, unlike in Marathon Mode. There are a total of twenty levels, each one at a higher speed than the last. Once all twenty levels are beaten, the player enters the bonus level. The bonus level is a semi-invisible level. Blocks alternate between being visible and invisible. The blocks are invisible for increasing longer time periods as the level progresses. There is no limit on how many lines the player can clear, and the player only loses when the blocks reach the top of the field. This game mode is not available on the Facebook version.

Tetris 1989[edit]

This mode attempts to simulate the classic Game Boy version of Tetris. There are two modes within this game. Mode A challenges players to clear as many lines as possible. Once certain goals are reached, the speed increases. Mode B requires players to clear a specified number of lines. These are similar to other game modes, but the rotational system of the blocks is slightly different, and there is no hold feature, making this mode more difficult. This game mode is not available on the Facebook version.


N-Blox mode is similar to Tetris 1989. It does not use many of the new features such as the hold function and the four block preview. Players are also not allowed to change the keyboard controls, which they can in every other mode. The goal is to score as many points as possible. The speed increases after a certain number of lines are cleared. This is similar to other standard Tetris modes available in other games. This mode is not available on the Facebook version.


This mode is similar to the N-Blox and Tetris 1989 modes. There are no hold pieces, ghost pieces, or four piece preview. The game is endless and challenges players to achieve the high score. This game is a remake of the first Tetris game that was released on Facebook. It is only available to play on Facebook, and is not found on the Tetris Friends website.


Battle 2P[edit]

In Battle 2P, the player plays against a previously recorded game that was played by another person, or even the player himself. The goal is to KO the other player three times by forcing them to reach the top of the screen. Players can send garbage, blank lines of tiles that cannot be cleared normally, to the other player by clearing multiple lines with a single piece, by clearing lines with consecutive pieces, or by performing the t-spin maneuver. 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. Players earn stars when they win. Once enough stars have been earned, the player is promoted to the next rank where he is matched up with better players. There are a total of twenty ranks attainable.[5]

Battle 6P[edit]

This mode is very similar to Battle 2P. The player is pitted against five other opponents this time. The opposing players are also recordings as in Battle 2P. 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. There are also twenty ranks as in Battle 2P. This mode is not available on the Facebook version.

Sprint 5P[edit]

In Sprint 5P, the player is playing against four others players in the basic Sprint Mode. The players are previously recorded as in Battle 2P. The goal is to clear forty lines before the other players. Players earn stars by placing first or second, and they lose stars by placing fourth of fifth. Once enough stars are earned, they advance to a new rank just as in Battle 2P.


Arena is the only live multiplayer mode. It pits up to six players against each other in real time. It works similarly to Battle 6P, except that when a player is KO'd he is out of that round. There are also items available in the game. When special flashing blocks are cleared, the player is awarded with a randomly selected item that harms the opponent in some way. Items can cause more garbage, speed up the game for the opponent, or even make the blocks invisible, amongst other things. The player is awarded points based on how well he does, how many lines of garbage he sent, and how many people he KO'd. Once a player earns 1,000 points, he is promoted to the next rank. If his points reach 0 because he lost points in a match, he is demoted a rank. This mode is not available on the Facebook version.

Rally 8P[edit]

In Rally 8P, the player has to race to the bottom of the field by clearing all the blocks. The player has to race against 7 other previously recorded players. The mode features cascade rules, which allows blocks to fall all the way down if the blocks below them are removed. Items are also available in this mode as in Arena. Wins earn stars, which allow promotion like most of the other multiplayer modes. This mode is not available on the Facebook version.
