"TETR.IO" has multiplayer and singleplayer modes. There are 4 singleplayer modes and 3 multiplayer modes.
TETR.IO differs from most other games with things such as a standard "change on attack/change per attack" attacking system, a new attack table with a "multiplier" system, adjustable tuning along with Soft Drop Factor and DAS Canceling Delay settings, etc.

=== Blitz ===

Blitz is your 2 minute score attack run, like [[Ultra]]. The twist is that there is a leveling system, that multiplies your score with each level passed. Not only do these Levels multiply your score, they increase gravity as well. It takes 3 lines to get to level 2, 5 lines to level 3, etc. Oddly, at level 11, the goal to level up (to level 12) increases by 3, (24) but then returns to the basic +2 format. (Level 12 to Level 13 would take 26 lines)

====Combo System====
TETR.IO's combo system uses a logarithmic scaling exclusively for single combo line clears to nerf 4-wide strategies, but also buffs big attacks the longer a combo goes, rewarding downstack combos that end in large spikes.


===Mechanics===

Including modern stacker staples such as Garbage(notably using "change on attack" randomization rules), Gravity, and the quintessential Line clear, TETR.IO contains several miscellaneous mechanics that offset it from other games.


====Back-to-Back Chaining(B2B)====
====Back-to-Back Chaining(B2B)====
To take advantage of this mechanic, one must preform several "difficult line clears", meaning Quads and T-Spins, without clearing singles, doubles, or triples in between each difficult line clear. This is known as a Back-to-Back, and they are rewarded in other Tetris games and clones by adding one line of garbage to an attack.

When player achieve level 10, player can started to play TETRA LEAGUE, and anonymous player cannot play this mode. Each game of TETRA LEAGUE is a 1v1 match, with a FT3(First To 3), FT5(First To 5) or FT7(First To 7) format based on one of the players' rank. The rating system is called '''T'''etra '''R'''ating ('''TR'''), which is based on Glicko-2. TR increases for each win and decreases for each loss exclusively. When playing this mode for the first time, the player must play at least 10 ranked matches, referred to as the "rating games", to display their TR. A letter rank is assinged to all players with less than 100 RD (short for Rating Deviation) based on their percentile in the leaderboards. RD normally decreases to a lower limit of 58 RD every time the player plays a TETRA LEAGUE game, and slowly increases at a flat rate of 1 RD per day after a week of inactivity, leading to a maximum of 350 RD.
After Ahpla 6.3.3

TETR.IO is an online browser game made by osk (as in ki-osk) currently in alpha development. It mainly features competitive one-on-one gameplay with a limited set of singleplayer modes. There are 4 singleplayer modes (Sprint, Blitz, Zen, and Custom) and 3 multiplayer modes (Quick Play, Custom Rooms, and Tetra League). It was originally in INDEV on Feburary 19, 2019, went INFDEV on January 31st, 2020, and went Alpha on March 22nd, 2020.

TETR.IO differs from most other games with things such as a standard "change on attack/change per attack" attacking system, a new attack table with a "multiplier" system, adjustable tuning along with Soft Drop Factor and DAS Canceling Delay settings, etc.

Singleplayer Modes

Singleplayer has 4 modes, which are Sprint, Blitz, Zen, and Custom. A 5th one was available for a limited time, called "5,000,000 Blast", to celebrate the game reaching 5 million registered members.

Sprint

Sprint is a mode where players are tasked to clear 40 lines in the fastest time they can. While nothing new, you can do specific tasks in this game mode to unlock 3 Badges.

These tasks are:

Secret Grade: Complete the Secret Grade pattern and you will be awarded the Secret Grade badge.

20TSD: Clear 40 lines using 20 T-Spin Doubles. Doing this will award you the 20TSD badge.

10 PCs: Make 10 Perfect Clears in Sprint. Not all PCs need to be 4 line. There just needs to be 10 PCs in the run in order for you to get the 10 Perfect Clears badge.

Note that Secret Grade is not specific to 40 Lines and can be cleared in any singleplayer mode except Zen.

Blitz

Blitz is a 2 minute score attack run, similar to Ultra gamemodes in most other modern games. In TETR.IO, Blitz has a twist in having a leveling system that not only multiplies one's score points but also increases gravity with each level passed, similar to the standard Marathon modes in all of the modern Tetris games. It takes 3 lines to get to level 2, 5 lines to level 3, etc. Oddly, at level 11, the goal to level up (to level 12) increases by 3, (24) but then returns to the basic +2 format. (Level 12 to Level 13 would take 26 lines)

Similar to other score attacks, Perfect Clears award a large amount of points. The score chart for each action is shown below:

Action Points Awarded
Single 100
Double 300
Triple 500
Quad/Tetris 800
T-Spin (No lines) 400
T-Spin Single 800
T-Spin Double 1200
T-Spin Triple 1600
T-Spin Mini (No lines) 100
T-Spin Mini Single 200
T-Spin Mini Double 400
All Clear/Perfect Clear 3500
B2B (Back to Back) x * 1.5 (x meaning the value of the clear)
Combos x * 50 (x is the value of the combo number, so combo 1 = 50 points, combo 2 = 100 points, etc.)

Unaffected by the level multiplier, Soft Drop gives you 1 point per cell dropped and Hard Drop gives you 2 points per cell dropped.

Zen

In Zen, the player can choose between many settings in the Zen menu. It contains a levelling system similar to one of Bejeweled's modes. Players can easily set settings through the sidebar and change settings like gravity, cheese, payback garbage, rotation and spin systems, etc.

Custom

In custom, the player can specify even more settings than Zen, such as board size, rotation, etc. Usually used just for fun. (You can press Ctrl-Z to undo and Ctrl-Y to redo)


Multiplayer Modes

In TETR.IO, there are 3 types of multiplayer modes; TETRA LEAGUE, QUICK PLAY and CUSTOM ROOM.

Mechanics

Combo System

TETR.IO's combo system uses a logarithmic scaling exclusively for single combo line clears to nerf 4-wide strategies, but also buffs big attacks the longer a combo goes, rewarding downstack combos that end in large spikes.

TETR.IO-ComboSystem.png

Back-to-Back Chaining(B2B)

To take advantage of this mechanic, one must preform several "difficult line clears", meaning Quads and T-Spins, without clearing singles, doubles, or triples in between each difficult line clear. This is known as a Back-to-Back, and they are rewarded in other Tetris games and clones by adding one line of garbage to an attack.

TETR.IO takes this idea one step further, and rewards the player according to how many Back-To-Back line clears one can clear in a row:

Range of concurrent, unbroken "difficult line clears" done in a row The corresponding visual "B2B" indicator shown Garbage added to the line clear's normal garbage amount
0-1 (none shown) 0
2-3 B2B x1-B2B x2 1
4-8 B2B x3-B2B x7 2
9-24 B2B x8-B2B x23 3
25-67 B2B x24-B2B x66 4
68-185 B2B x67-B2B x184 5
186-504 B2B x185-B2B x503 6
505-1370 B2B x504-B2B x1369 7
1371-(unknown) B2B x1370-(unknown) 8


Tetra League

Rank distribution chart

When a player achieves level 10, they can play TETRA LEAGUE. Anonymous players cannot play this mode. Each game of TETRA LEAGUE is a 1v1 match, with a FT3(First To 3), FT5(First To 5) or FT7(First To 7) format based on one of the players' rank. The rating system is called Tetra Rating (TR), which is based on Glicko-2. TR increases for each win and decreases for each loss exclusively. When playing this mode for the first time, the player must play at least 10 ranked matches, referred to as the "rating games", to display their TR. A letter rank is assigned to all players with less than 100 RD (short for Rating Deviation) based on their percentile in the leaderboards. RD normally decreases to a lower limit of 58 RD every time the player plays a TETRA LEAGUE game, and slowly increases at a flat rate of 1 RD per day after a week of inactivity, leading to a maximum of 350 RD.

Quick Play

Quick Play was a public FFA room. When the room's number of players exceeds 100, Super Lobby Mode will be engaged, a reference to the Hard Drop Super Lobby community events beginning in October 2019 on Tetris 99. The winner achieves a Badge called Emerged victorious in a 100+ player game. This also applies to custom rooms.

Quick Play 2

Quick Play 2 replaced Quick Play on July 26 2024 for the new Tetrio season. Quick Play 2 has the player climb the Zenith Tower. The player climbs the tower by clearing lines and KO enemies. There are 9 floors the player can reach, after reaching a floor a card gets unlocked that can be activated before starting again. The leaderboard resets each week.

Custom Rooms

Players can create a public or private room. A Room ID consisting of 4 alphanumeric characters is generated after room creation, which can be shared to other players to join that room.

Public rooms can be accessed through ROOM LISTING. Private rooms can be accessed either by entering a Room ID or an invitation from a friend.

One can change many settings in a custom room. These include the spin system, the passthrough modes (passthrough is when, due to network delays, attacks will literally ‘pass through' each other), the garbage multiplier, the gravity, and more.

Trivia

If a player KO's or gets KO'ed by osk, they can receive these multiplayer Badges:

KO by TETR.IO Founder: KO osk in any gamemode

KO'd by TETR.IO Founder: Get KO'ed by osk in any gamemode
