This mode is very similar to Sprint; however, instead of line completion, you are aiming for a score. This means you're likely better off doing line completion combos (getting consecutive line completions with each tetrad drop) or by doing T-block spins (Tetris Friends calls these T-spins).The time limit is the same (two real minutes) so you need to use various dirty tricks to set-up a situation to score. Score big and quickly, because time marches on. Tetris Battle 2P and Battle 6PThe only difference between 2P and 6P is the randomized element of penalty lines being added into your playfield from opponents. Battle 6P mode also offers preset maps (to start your line combos and T-spins) but more on that later.The goal is simple - in two minutes time, 'score' higher than your opponent(s).

But what determines score?. Knockouts delivered.

To complete the Mission, you must complete 7 games of Battle 2P with a Max Combo of 7 or higher within 7 days to earn this badge and 100 tokens. Tips As suggested on the missions release, it would be advisable to use the multiplayer.

The more opponents you knock out (by filling up their playfield with blocks) the higher you will rank. If the number of knockouts is tied the next condition is looked at. Lines completed. The player with the most lines completed will rank ahead.

This is the usual determining factor (not KO's) in 6P matches. If there is a tie among players for lines completed, the next condition is used to determine the winner. Overall height of blocks.

The player with the lowest height will win. If you accumulated a very high stack to set-up your tetris line clears, you will likely not be ahead in this category - better clear a great many number of lines and KO enemies to get ahead!Tetris Battle 6P MapsAs mentioned before, the Battle 6P mode has different maps you can select to start your combos and Tetrises off. Here's a quick breakdown of each map:This the classic random block set-up. You can easily swing (rotate/shift) a J-block into the bottom right or an L-block on the bottom left. Worming blocks into the lower corners will somewhat speed up the process of getting rid of the obstructions.Note that I, O, T and Z/S blocks will not be able to rotate/shift under the first layer of obstacles as they will instantly collide with the obstructions.This concentrates a bunch of blocks into a quadrant but leaves a small hole in the corner.

In a way, this is the opposite of the map 'Monster' but it is slightly easier to break into the empty cavity because there is an easy chute for an I-block on the right side.The problems add up once you don't take into account the assymetry of the stack. Despite it looking like a perfect sphere, it is offset so thin blocks (I, J, and L) slipping into the right side tend to fall straight through but they will be blocked on the left side.This map is one with a 2-block wide chute, showing you what can be done to make line combos work. Once you start piling in J and L blocks, you can begin to see you'll need I-blocks to keep the combo going.Should you start the line with Z/S blocks, you will need to keep using them as well as the occasional T-block to hammer out the blocks left over after line clears.Note that the top of this map thins out for you to place tetrads you don't have room for. Use it to build a solid vertical wall to keep your line combinations ongoing. If you are able to construct well formed (and solid) stacks on both sides before you start your line combinations, you will likely be able to Knockout an opponent.This map is not intended for rotation (it's more for show) but if you manage a rotation, it will likely not be the Tetris Friends recognized T-spin.Because the covered spaces are rather cavernous, use a conservative approach.

Open the tops of the empty cells, then quickly fill them with tetrads to open up more. Use care when doing this as you do not want to pile on more blocks you need to uncover later.As part of your strategy, you may even forego uncovering the spaces and simply use the leftover pits in the stack when needed to complete lines.

Since you only have two minutes anyway, spending the time uncovering empty spaces will result in a less than spectacular rank.This is a shorter stacked version of Combo King and it is certainly better for some players who like building square stacks. It otherwise has the same 2-block chute for line combinations.The only difference between this map and Combo King is that if you start doing line combos immediately, you will grind down the stack much faster.The opposite 'Jon Bovi' map of Smiley. There is a cavern in the bottom right corner but the rest of the stack is terraced in a way to frustrate you.Focus on uncovering the hole on the right side first (the monster's mouth) then pare off the slope of the monster's head. Once you've uncovered the map's empty corner, things should go much easier - don't forget that the blocks in the middle can be exploited to build your stack for a tetris.This map is a good version of Combo King.

The chute is 4-blocks wide, giving you more room to manuever tetrads, but also requiring more than one tetrad to start the line combination.Only I-blocks will be able to trigger a line combination if you did not fill the chute with other blocks like Z/S and J/L blocks. Don't be afraid of holding O-blocks if they will get in the way; unlike Combo King, you cannot stack away unwanted tetrads because the sides of the stack have reached the very top.The cornerstone of this map are the three neatly arranged T-block spaces you can T-spin into.While it is usually the case where you can T-spin two T-blocks together (by exploiting the hold function), sometimes you will be able to connect three T-spins together (because a third T-block will appear in the upcoming queue).Should this fortunate (the blocks you get are random) event occur, give it a shot. It will be the easiest three T-spins you will get. Once the stack is gone, fall back to getting rid of things the old fashioned way.Unless you are an able-skilled practicioner, you will be hard pressed to create successive T-spin spaces to pull off combos. Far better to square off your stack and shoot for tetrises, doubles, or triples.Tetris Marathon and SurvivalMarathon requires you to complete 15 levels of Tetris, whereas Survival requires you to survive 20.

Unlike the other modes, Marathon and Survival will accelerate the falling speed of tetrads as you complete levels.This means while you can still do a Hold or view the ghost tetrad, the speed at which the blocks fall will steadily increase until they are just a shade slower than a hard drop.Gauge the drops carefully and complete as many lines as possible - in a way, the goal of setting up a tetris and then completing them hasn't changed. Just be aware that as the speed of the tetrads increases, you cannot afford to make mistakes (and you may have to settle for singles, doubles, and triples).Getting a knack of paring down your stack height is also a good skill. Keep the height low and the formation of the blocks in the stack tight. Once blocks start falling like rain, you will not have the luxury of hesitation. Tetris 1989 and N-BloxThese two modes are classic modes. The Hold Function and the hard drop are not available, but the ability to do tetrises, block sliding and rotation are still valid.

Simply play and score your highest score for tokens and advancement.If you're good (and survive fairly long) at the middle and higher levels of these classic modes, you should have little trouble in the other competitive modes of Tetris Friends.

From Hard Drop - Tetris Wiki

Tetris Friends was a Tetris game available on its own website. Registered users were able to compare their scores with their friends and with the entire community. It was the only official Flash implementation of Tetris made by the Tetris company itself with over a million registered users. A Facebook version was released and was available until 2012. On June 1, 2019, the game is no longer available, with Tetris Battle also not available.

Expert Plus (E+) mode:

• The assumption is that in all modes, combos above 12 will generate 5 lines for each line cleared.

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.

Can be played in all versions

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.).

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 excellent system performance, namely a good network and graphics card.

• ARR - Auto Repeat Rate: controls how fast the pieces slide left and right.

• IHS - Initial Hold System: allows holding the next piece during line clear delay.

• IRS - Initial Rotation System: allows the next piece to be rotated during line clear delay.

Hidden Missions

As you complete premium missions, which cost rubies, you fill in a grid which will unlock hidden missions once you complete a row. Below are a list of the known hidden missions (acknowledgements to Bigwig, Pikiwedia, and Ravendarksky):

• [Row 1 HM] For the Glory: Perform 10 Tetrises and 10 T-Spins in a single game of Marathon within 7 days.

• [Row 2 HM] Hotline Deluxe: complete 10 hotlines in a single game of ultra in 7 days.
  

• [Row 3 HM] Limbo Bar Deluxe: Beat 3 games of 2p consecutively while staying under the limbo line.
  

Comment: This one is annoying because by the third game the bar is so low it's easy to break above it. Losing a 2P game does not cause the 3 game consecutive to reset IIRC but breaking the limbo bar does.

• [Row 4 HM] Hotlines: Complete all 40 lines on the HotLine.
  

Comment: While HMs 5 and 6 are currently unknown, this is reported to be the only mission that's fun or worthwhile.

Hidden Missions 5 and 6 currently do not exist because Tetris Friends has halted the development of premium missions.

• [Row 5 HM] ?
  
• [Row 6 HM] ?
  

Arena Modes

After progressing beyond the silver class, the option of Expert Mode and Expert Mode + become available when making a room. A Purple E or E+ in the upper right of a game room will indicate the mode. It is highly advised that all games be played in Expert + mode.

Expert Mode: Speed increase, consistent garbage shifting, and sequential targeting.

• Speed increase means higher gravity which means that tspins are quicker and therefore more powerful. Your tspins will start to misfire if you jump back and forth from these gravity modes. The gravity in Sprint is the same as Expert mode while unfortunately Ultra, Battle 2P, Battle 6P, and even Sprint5P have that of normal gravity.

• Consistent garbage shifting means that every discrete combo or line(s) cleared will create a hole in a different spot. In normal mode you tend to get only one giant hole which tends to make gameplay silly.

• Sequential targeting means that the gunscope, which shows where your lines and/or items will be sent, will move predictably from left to right rather than randomly. But please be sportsman and do not abuse the targetting feature to bully other players.

Expert + Mode: Contains all features of Expert Mode plus the following: garbage block, combo attack adjustments, and extended time.

• Garbage block was adapted from Tetris Online Japan (TOJ) and gives you an opportunity to combo to stall and/or counter your red bar. The red bar shows how many lines will be sent to you unless you combo. When you lower the red bar to counter, your lines are absorbed and none are sent to other players and those lines will not be a part of your 'lines sent' total at the end of the match. Surplus lines after the red bar is eliminated will be sent.

• Combo attack adjustments. As consistent garbage shifting makes combos much more deadly since they produce messy garbage, the number of lines sent from combos is slightly reduced as shown in the chart.

• Extended time. The hurry-up garbage begins at 2 minutes.

Survival

This mode features similar objective as marathon, but has different goal system.Level advances by clearing every 10 lines. After beating 20 levels, you'll enter the 'Bonus Level'.The bonus level is semi-invisible challenge, and the game continues until you top out.This mode is available only in website version.In Facebook version it was available as a Holiday mode, but it isn't available.

1989

This mode simulates the Game Boy version of Tetris, but it is inaccurate.For example, DAS is somewhat faster, the gravity at level 15 is slower than original, and it has lock delay (Tetrominos lock down when soft dropped).In most regards, the rotation in this mode resembles the one used in Tetris DX, except only S and Z twists can be performed.Both the A and B type game can be played, but B-type game doesn't have a separate leaderboard.

N-Blox

Although this is not a real game mode, it can be played in website version.

The mode is meant to feel old-school, so most features in modern Tetris games, like Holds or longer Next Queues, do not appear.

Unlike other modes, you can't change keyboard mappings in this game.

The mode was developed by Paul Neave, who is known for his Chrome Experiments and flash games, making N-Blox the only mode in Tetris Friends developed by a third party.

No longer available

Acorn Drop

A 150 lines marathon game based on the Ice Age animated film series. All pieces have the same colors and designs, that of an acorn. This was a promotional game and is no longer available.

BlockStar

This mode is a remake of the first Tetris game released on Facebook.It has classic game elements: no Hold Queue, no Ghost Piece, classic lock (no lock delay), only one piece preview, endless game time, etc.This mode is unavailable.
