Connected Update: Multiplayer Modes



The piece falls the entire height of the matrix instantly.

The randomizer system used in Tetris Effect. Every sequence of 7 pieces consists of one of every Tetrimino in the game.

All/Perfect Clear
The state of clearing all Tetriminos on the Matrix after beginning play.

Attacks Per Minute- the number of lines sent to your opponent, averaged over a 60 second period.

Auto Repeat Rate: The frequency with which a piece repeats a held left or right input.

The act of clearing only consecutive T-Spins and Tetrises. Not to be confused with Combos.

A term for a stack of garbage rows where the one missing hole in each does not create a neat, tidy well. Taken from Swiss cheese, which is typically full of holes.

The act of clearing sets of lines without interruption.

Delayed Auto Shift: the amount of time before an input is repeated/ARR is engaged.

Refers to clearing lines to lower the stack in the playfield.

Drops/Pieces per Minute: the number of pieces you place, averaged over a 60 second period.

A section of the stack that requires a certain piece or pieces to make flat.

Entry delay
The delay between locking a piece and the next piece spawning. Also called “ARE.”

The ability to place pieces using as few key presses as possible.

Flat stacking
A strategy for placing Tetriminos that increases the chances the player will be able to accommodate the next pieces.  The stack, when flat stacking, should be flat but not too flat.

Performing moves with no specific pattern in mind.

Four-wide (4w)
A strategy that leaves 4 consecutive open columns with 3 pieces of residue inside, used for combo chaining. Typically done in the center (c4w) or to the side (s4w) of the board.

The lines you send to your opponent as a result of clearing multiple rows from your field with only one Tetrimino. These appear at the bottom of their field with one piece missing. Your opponent can similarly add garbage to your field in the same manner.

The rate at which pieces fall to the bottom of the matrix. The higher the gravity, the faster the active piece moves to the bottom of the matrix/field/stack. The fastest gravity in Tetris Effect: Connected is called ‘20G’ where a new piece instantly starts on the stack before it can be moved or rotated.

Initial Hold System: The ability to hold a piece before the next piece is spawned.  Often used by advanced players.

Initial Rotation System: The ability to rotate a piece before it spawns. Often used by advanced players.

The 20 row by 10 column board in which the pieces are placed.

An informal term that means an effective strategy or way to achieve the goal of the game, whether it’s to beat other players or beat the game itself.

Nintendo Rotation System – the name for the rules of rotations in NES and Game Boy Tetris.

Perfect clear – When you clear the entire playfield. Also known as a “Full Clear” or an “All Clear.”

Perfect Clear Opener, see Openers.

Soft Drop Rate – the speed at which a tetrimino falls toward the bottom of the matrix when the soft drop key is held. In Tetris Effect: Connected, the SDR is fixed and cannot be changed.

Super Rotation System – the name for the set of rules that define how rotations, kicks, and spins operate in all official modern versions of Tetris.

A matrix with pieces placed — a board made of previous pieces that you manage.

Rotating a T piece to put it into a T-shaped hole, scoring a bonus based on the number of lines cleared.

One of the seven different shapes made from 4 blocks that are used in Tetris.

Tetris/Tetris Clear
The act of clearing four lines at once, typically using the I-Tetrimino (The long bar).

Two wide (2w)
The two wide is a well with two columns open. Left, Right, and Center describe the location in your board. 

This refers to placing tetriminos to raise the height of the stack.



1. Stacking Strategies

9-0 Stacking and Clean Stacking

What does this mean?

The main goal of Tetris is to drop Tetriminos into the playfield and clear lines to gain points.  A line or row is cleared when all 10 columns in the row are filled.  One of the most common strategies for doing this is called 9-0 stacking, better known as a side Tetris well/rightwell, which is when you leave a one-column stack on either the left or right side of the stack, leaving opportunities for clearing Tetrises. This is a great place to start if you want to improve your score.

Stacking cleanly refers to flat stacking for a clean and accommodating stack with few or no bumps. 

How do you learn it?

9-0 stack: the number one thing to keep in mind is that one of the side columns needs to be empty. As long as you can maintain this, you are 9-0 stacking.

Stacking cleanly, however, can be a bit more tricky. The main thing to think about is how pieces connect together.

Ultimately, learning to stack cleanly doesn’t really have any shortcuts, as it’s something that’s entirely based on intuition. The only way to get better at stacking cleanly is to play more Tetris.

9-0 example:

Once you’ve gotten the hang of stacking cleanly, you can try to start to offset the Tetris well towards the center. The name “9-0” stacking refers to the width of the stacks on each side of the Tetris well; in 9-0’s case, nine columns to the left, zero to the right.

Freestyle Stacking

A common form of freestyle stacking is 6-3, where a three-wide stack is on the right-hand side. This can be quickly made using the L, O, and J-pieces.

This stacking is more popular due to its ease of use and ability to form T-Spin setups at the very top of a flat 6-3 stack.

While any other form of freestyle stacking (9-0, 8-1, 7-2, or 5-4 stacking) can give you T-Spin setups, they can be a bit more counterintuitive or rely too much on  a certain piece to work. You can try any of these options, as long as you maintain a constant stack width on each side of the Tetris well.

2. Simple Kicks and Piece Movement

What does this mean?

Modern Tetris games follow a specific rotation system, the Super Rotation System (commonly referred to as SRS). This system dictates how the piece rotation behaves in the matrix. Pieces typically rotate around a given center point; however, there’ll be situations where a piece can’t use that center point to rotate. This is where the kicking mechanic comes in. What kicks do is change the center of rotation of the piece, allowing the piece to still rotate, albeit a bit differently.

3. Downstacking

What does this mean?

By now you’ve learned how to build stacks, now it’s time to discuss the opposite; clearing them. You might be wondering, “Clearing lines is simple; why would I need to learn how to do that?” The thing is, there will be situations where you make a mistake while upstacking, and your stack will become messy. In these kinds of scenarios, clearing the lines to get back to your normal stack will be easier said than done. That’s where more complicated downstacking comes in handy.

How do you learn it?

The best thing to keep in mind for downstacking is how each Tetrimino clears lines; not just how many lines they clear, but also what’ll be left behind after you perform a line clear.

If you want a perfect practice tool for downstacking, try playing the Purify Effect Mode. More details about Purify are in the Effect Modes section.

Downstacking example:

4. T-spins

What does this mean?

A T-spin is a type of tuck/spin using the T piece. In guideline versions of Tetris, a spin is considered a T-spin if three “corners” are filled. You can tell when you hear a clunk sound when you rotate.

How do you learn it?

The first thing to look for when it comes to setting up a T-spin is a T-shaped hole in your stack. If you have one of those, you can create an easy T-spin setup by simply creating a small overhang.

T-Spin example:

This image shows what boxes are checked to determine if the placed T is a T-spin.  If at least 3 of the 4 red boxes are filled by other Tetriminos when the T piece is placed, it is considered a T-spin.

For a more comprehensive guide on T-Spins, you can check this video out.

5. Openers

What does this mean?

Openers are the equivalent to “strategies” for the beginning of the game; in other words, openers serve to answer the question “How should I start a game of Tetris?” Openers are often explained and learned in “bags,” in order to learn multiple ways to build a given pattern regardless of piece order (see 7-bag in definitions). Many openers aim to produce a high efficiency between “Tetriminos used” and “attacks per minute”, often utilizing T-spins.

How do you learn it?

As there are a vast variety of openers, there are many different ways to go about learning them. In fact, you don’t really need to learn them if you don’t want to.

However, due to the insane amount of openers out there, it’s hard to discuss them in a concise manner.A useful guide of commonly-used openers can be found at: https://four.lol/openers/practical-openers

Perfect Clear Opener Example
Perfect Clear Opener Example

This is an example of PCO. L, O, and J make a 3×4 block, with the T, S, and Z making the jagged shape on the left.

Grace System Opener Example
Grace System Opener Example

This is an example of the Grace system. L, J, O, S, Z, and I make a 6×4 box, leaving a 4×4 box that can be filled in many ways.

See if you can find a solution for these, they’re both solvable.

6. Advanced Kicks and Spins

What does this mean?

Although not rewarded by the game in the same way T-Spins are, you can use spins with other pieces to fix your stack more efficiently
L/J are really flexible
For S/Z, you need to keep the orientation of the piece in mind, but they can do useful spins
Spinning L/J or S/Z to clear a double can lead to a perfect clear

How do you learn it?

When you see somewhere where your piece may fit, don’t be afraid to try to fit it there; chances are you can spin it in the hole if you try enough!
Some games also have modes to let you practice to most useful spins (Tetris Effect’s All Clear mode for example)

Kick Example:

7. Tetris Effect-Specific Mechanics

The Zone

What does this mean?

The Zone is the core mechanic of Journey, Zone Battle, and Connected modes. During the zone, blocks stop falling, and all cleared lines are moved to the bottom instead of disappearing. Different names are given to different amounts of Zone line clears

4-7 lines = Tetris

8-11 lines = Octoris

12-15 lines = Dodecatris

16-17 lines = Decahexatris

18-19 lines = Perfectris

20 lines = Ultimatris

With planning, strategy, and a little luck, clearing more than 20 lines is possible! 

21 lines = Kirbtris (named after the first person to succeed, Kirby703)

22 lines = Impossibilitris

A 23 line clear is currently named Impossibilitris and has only been achieved once. It’s the maximum possible in Journey mode.

24 and up are also currently named Impossibilitris, and 24 has only been seen once, by Electra via a careful setup in Connected VS.

How do you learn it?

There are a few things to take into account when shooting for a high zone line clear: 

Your zone meter: The first is your zone meter, which is charged by clearing lines. The meter charges in increments of one quarter. Each quarter needs a set amount of line clears, depending on the gamemode and level. One quarter gives you five seconds of zone time. A full zone lasts 20 seconds. 

Speed: When shooting for around 16 lines or under, the key element to getting more lines is how fast you can clear lines. Starting your zone with lots of blocks on the board leaves you with more time to clear lines and less time wasted stacking. Although it is possible to get 16+ lines in a zone with a quarter or half meter, it is much easier to do so with a higher-filled meter.

Using a strategy like the side two wide or right well can be very good for getting more lines. The side two wide allows you to clear lines very quickly as you can use each piece to downstack, but sacrifices a bit on efficiency/score. Right well is more efficient in terms of score but is dependent on having lots of I pieces during the zone. 

When shooting for 16+ lines an important factor that comes into play is topstacking. When in the zone, if a piece spawns inside another block or is placed entirely above the 20 tall playfield, the zone will end. Due to this, when playing in the zone near the top of the stack, it becomes very important to make sure your piece will not prematurely end the zone. Clearing quickly through the first 16 lines can also give you more time to think about your stacking at the top of the zone.

For even more advanced zone techniques, read on!

Trying to achieve 19-20 line zones is where topstacking begins to become really difficult. Sometimes it is a good idea to take a screenshot and look to try to find a solve (if you are in single player). Some general tips are to remember that you can place pieces partially above the 20 tall field. Also, try to fill in the sides first, as to avoid having a piece spawn in a block. This is something that may take a lot of practice to learn, so don’t get discouraged if it takes you a while to get this.

The final challenge in zone lines are 21+ zones. Since the board is only 20 lines tall it may seem confusing that you can clear above 20 lines. Due to the fact that you can place a piece partially above the field you can actually clear lines above the field. It is also important to utilize IRS and IHS. Since it is complicated to learn, a more in-depth guide is linked here.

Other Tetris Effect: Connected Mechanics

Journey Mode: In Journey mode, the meter fills based on the level being played: it takes 7 lines to fill a quarter of a zone on Beginner difficulty, 8 for Normal, and 10 for Expert.

Zone Battle: In Zone Battle, the meter fills based on how many lines are cleared, with more lines needed to fill the Zone as you progress through each phase. More about how Zone Battle progresses, as well as the goal in Zone Battle, is explained below.

Zone example:

Connected zone example:

Do note that magic minos (the purple blocks that cascade) deal significantly less damage!!! Avoid using them to cascade clear lines to maximize your damage to the boss.

8. Gamemodes – Effect Modes

Marathon: A staple of Tetris games – clear 150 lines as the speed steadily increases, with the highest score! Also has an Endless variant.

Ultra: Another staple of Tetris games – get the highest score possible in three minutes!

Sprint: Another staple of Tetris games – clear 40 lines as fast as possible!

Master: A difficult test of endurance, speed, and reaction time inspired by the Tetris: the Grand Master series of arcade games. Pieces spawn touching the stack at 20G with a short amount of time to manipulate pieces before they lock into place. Levels advance every ten lines from level M1 until M30, ramping up in difficulty. After clearing 300 lines, the game ends. Few people have completed this mode.

Chill Marathon: Like Marathon, but with customizable goals and topping out is not fatal. Just keep playing until the end!

Quick Play: Pick a level seen in Journey mode (or one of the secret unlockables) without any risk of a game over.

Playlists: Four curated back-to-back levels at low gravity and 30 lines apiece.

All Clear: The goal is to use the given piece sequence and unique spins to clear the whole matrix, getting as many All Clears as you can before you run out of time. The colors of the lines help identify what they should be cleared with if playing with Traditional colors. Additionally, note that you must clear a line with every piece, even if you can still get an All Clear.

A gif for each All Clear board, including a few slightly faster solutions, can be found here.

Combo: Clear as many lines in a row as possible without dropping a piece that doesn’t perform a line clear. A new board will generate upon stopping a combo or clearing all rows of given garbage on each board.

Target: Clear glowing blocks as fast as possible by performing line clears on those rows. The game generates a new board once all glowing blocks are cleared on a board.

Countdown: Five minutes of score attack, but I-tetriminos fall down from the top of the matrix after a certain number of pieces are dropped. Before each drop, the column(s) where I-tetriminos will land are indicated by a faint glow. Clearing lines with these pieces are rewarded as Countdown Clears and receive extra points. Also has an Endless variant.

Purify: Three minutes of downstacking. Boards spawn with garbage lines and glowing purple “infected” blocks that can be eliminated with line clears. The player is rewarded points for clearing infected blocks with a bonus for clearing all infections on a board. When all infected blocks are eliminated, a new board is generated.

Mystery: Like Marathon, but the player is under constant attack by various effects. Effects occur after 10-15 pieces are placed. Also has an Endless variant.

Connected Update: Multiplayer Modes

With the Connected update, the following game modes are available after clicking the new category Multiplayer in the main menu (if you owned the Connected version before the summer release, this part has not changed).

Connected: Connected is a three-player mode where you play as one of three “guardians” to fight against an AI “boss”. The goal is to survive the boss’ blitzes and use a combined zone mechanic to sent lines to the boss and win.

Connected VS: A limited-time gamemode that occurs during the weekend. It is similar to Connected, but a fourth player is able to play as the boss. The guardians attempt to defeat the boss, while the boss attempts to make all three guardians top out. 

Zone Battle (ZB): Zone Battle takes the standard Vs. Tetris format and adds the new Zone mechanic to it. 

In a Vs. Tetris game, your goal is to make your opponent top out by clearing lines to send them “garbage”. The general thing to note is that the more lines you clear at once, the more lines of garbage you send to them, with things like T-Spins, All Clears, and Combos giving some bonuses.

However, with the inclusion of the Zone mechanic, you gain the opportunity to take what you’ve learned about using the Zone in Journey Mode into a more competitive setting.

Charging Zone in Zone battle works similarly to how it does in Journey Mode; the more lines you clear, the more Zone you charge. Things like T-Spins and All Clears don’t matter for Zone charge.

Once you activate Zone, any and all incoming garbage won’t affect your matrix until it’s over.

After your Zone ends, you’ll send garbage dependent on several factors:

  • The amount of lines you cleared in Zone
  • How much Zone charge you had upon activating it
  • Bonuses like Tetrises, T-Spins, Combos etc.

Score Attack (SA): Score attack is another 1v1 gamemode, with the goal being to score the most amount of points in a modern Tetris match.

This mode is essentially the same as Marathon, with a few additions:

  • Level selections: Unlike marathon mode, the level to start is restricted depending on your SR. When you begin, you can select anywhere from lvl 0-5, and the starting level shifts up depending on your SR (5-10, 10-15, and 15-20)
  • Goal: The goal isn’t to get the highest score you can, rather a higher score than your opponent.
  • Timer: because the goal is to get a higher score, if the person with a higher score ends their run early, the other player has up to 2 minutes to catch up or beat that score. If you can beat that score in 2 minutes or less, you win. If not, the other person wins.

Classic Score Attack (CSA): Classic Score Attack works in a similar way to Score Attack, but with one key difference: the mechanics in this mode work like that of the NES version of Tetris. Your goal is to score more points than your opponent, with the same RNG and mechanics as NES Tetris.

Similar to Score Attack, there is a level restriction that increases the level you can start depending on how high you climb the ladder, as well as a hurry up timer that gives you two minutes to catch up to your opponent’s score if they top out first.

If you’re familiar with watching the Classic Tetris World Championships (CTWC), this mode follows that formula, with the exception of the aforementioned timer.
