Tetris Speedrun Categories (40L, Marathon, Sprint)

Tetris speedrunning splits cleanly into two worlds: the modern guideline-compliant scene (Tetr.io, jstris, Puyo Puyo Tetris) and the classic NES Tetris scene (CTWC, the maxout era, the rolling technique). Each world has its own set of categories, its own records, and its own community. This guide walks through the main tetris speedrun categories on both sides — what each one tests, what the typical times look like, and where to watch the top runs.

The modern guideline categories

“Guideline” refers to the modern Tetris ruleset that The Tetris Company licenses for official games. Tetr.io and jstris are unofficial but guideline-compliant. They share core mechanics — Super Rotation System, 7-bag piece distribution, hold, ghost piece — which means times across these games are roughly comparable.

40-line sprint

The flagship modern category. Goal: clear forty lines as quickly as possible. Timer starts on the first piece and stops on the line clear that crosses forty.

Top Tetr.io runs sit in the 14-18 second range — the world record has been pushed below 14 seconds at various points. This is a speed that’s almost incomprehensible if you’ve only played casual Tetris. The runs use a standardized Perfect Clear opener (four pieces, all consumed, board empty after sixteen blocks) and then chain through Tetrises (four-line clears) for the remainder.

The reflex demand is extreme — pieces drop, rotate, and lock at rates that approach the limits of human reaction. Top players use rebindable controls with optimized timings (DAS, ARR) tuned to single-millisecond precision. Our Tetris sprint 40-line guide walks through the opener and the stacking patterns.

Marathon mode

Marathon is the long-form category. The original arcade Tetris is endless, but modern guideline games cap Marathon at 150 lines or 15 minutes. The optimization target is score, not time.

Marathon runs reward T-spins, back-to-back Tetrises, and combo chains. The points-per-piece curve makes Marathon a different game than Sprint — survival and score per line, not raw piece-placement speed. Top Marathon scores in guideline games involve continuous T-spin Doubles and Triples interleaved with Tetrises for back-to-back bonuses.

Quad-only sprint

A variation of 40-line sprint where every line clear must be a Tetris (four lines at once, called a “quad” by the competitive community). No singles, doubles, or triples are allowed — clearing them disqualifies the run.

The constraint means the run becomes pure four-well stacking. Players build a nine-column stack, leave the rightmost column open, and drop I-pieces vertically. The exact 7-bag distribution makes the I-piece arrival mostly predictable, but mistakes that force non-Tetris clears end the attempt.

Quad-only is harder than standard 40-line sprint at the world-class level because it removes the safety valve — you can’t recover from a stack mistake with a single-line clear.

Ultra mode

A score-attack category. Three minutes on the clock, maximize score. Like a compressed Marathon. Top Ultra scores involve continuous T-spins and stack management to survive three minutes without topping out.

20G mode

20G is a Tetris mode where pieces fall at maximum gravity — they appear at the top of the playfield and immediately drop to the lowest valid position. Players have to slide and rotate pieces into place using “finesse” — the technique of moving pieces along the playfield floor before they lock.

20G categories are smaller than 40-line sprint but represent the absolute skill ceiling of modern Tetris. Few players can play 20G fluently for sustained periods.

The classic NES Tetris categories

NES Tetris is a separate scene with its own ruleset, controls, and community. The Classic Tetris World Championship (CTWC) uses NES Tetris, and the scene’s records have transformed dramatically since 2019 with the discovery of the “rolling” technique that allows piece placement at higher levels than was previously thought possible.

A-Type maxout

A-Type is endless Tetris on NES. The goal is to reach the maximum displayable score (999,999 — the maxout) before topping out. For decades this was considered an extreme accomplishment; today it’s the entry point to top-tier NES Tetris.

The score depends on line clears and level reached. The killscreen at level 29 (where the game’s piece-fall speed exceeds the controller’s ability to move pieces using standard tapping) was considered the ceiling for years. The rolling technique lets players control pieces past level 29, which pushed scores far past the maxout into uncharted territory.

B-Type

B-Type is the NES Tetris mode where you start with a partial playfield of garbage and clear it. The category is fastest time to clear 25 lines under B-Type starting conditions. It’s a sprint-style category for the classic game, but the older controls and ruleset make it feel completely different from modern Tetr.io sprint.

Quad-only / specific-level categories

The NES scene also tracks specific score targets at specific levels (level 18 start, level 19 start, level 29 reach). These categories let runners specialize without committing to the absolute world-record chase.

How runs are verified

Speedrun.com hosts leaderboards for both modern Tetr.io categories and NES Tetris. Verification requires video evidence with the timer visible and an unbroken capture from start to finish. For 40-line sprint, the timing is taken from the game’s internal clock (Tetr.io and jstris both show frame-precise timing on the result screen).

NES Tetris runs use external timers because the cartridge doesn’t display run time. Most CTWC-era runs are captured on direct-feed video with timer overlays added in post.

Where to watch the top runs

For modern Tetr.io: the game’s own replay system records every match, and top players upload their best 40-line sprints to YouTube regularly. Tetr.io’s spectator mode also shows live high-rated matches.

For NES Tetris: the CTWC YouTube channel hosts the full tournament archive, and the major players (Jonas Neubauer, Joseph Saelee, Tristan, Blue Scuti, others) have personal channels with practice and exhibition runs.

For external context, the Tetris Wikipedia article covers the franchise and competitive scene at a high level.

How to start running

Pick the scene that matches your interest:

• Modern guideline: Install Tetr.io (free, browser-based). Start with 40-line sprint mode. Practice the Perfect Clear opener and the Tetris-stacking continuation. Target sub-60-second runs first, then sub-30, then sub-20.
• NES Tetris: Get an emulator or a real NES with a flash cart. Start with level 9 A-Type runs to learn piece patterns. Work up through level 18 and 19 starts.

The progression from “casual player” to “submitting to a leaderboard” takes weeks to months depending on practice intensity. Don’t expect to break records in your first session.

Frequently asked questions

What’s the Tetr.io 40-line sprint world record?

It’s been pushed below 14 seconds at various points by top players. The exact current record changes regularly — check the Tetr.io leaderboard or speedrun.com for the present number.

What’s the difference between Tetr.io and NES Tetris speedrunning?

Different rulesets, different controls, different communities. Tetr.io uses the modern guideline (SRS rotation, hold, 7-bag, ghost piece). NES Tetris uses the original NES game’s 2D rotation, no hold, and analog speed scaling. Records don’t translate between the two.

Is jstris the same as Tetr.io?

Both are guideline-compliant browser Tetris games. Tetr.io has become the dominant competitive platform because of more active development and a larger player base. Jstris records are still kept but the community center of gravity has moved to Tetr.io.

What’s the rolling technique?

A NES Tetris control method where players support the controller with one hand and tap the underside repeatedly with the other, achieving piece-move rates higher than single-thumb tapping allows. It unlocked playable speeds past the level-29 killscreen and transformed the top end of NES Tetris records.

Can you speedrun Tetris on a phone?

Mobile Tetris apps exist but mobile controls (touchscreen) are slower than keyboard input. Serious competitive Tetris speedrunning is done on keyboard (modern guideline) or NES controller / arcade-style controller (classic).

The bottom line

Tetris speedrunning is two scenes in a trenchcoat — modern Tetr.io with its sub-twenty-second 40-line sprints, and classic NES Tetris with its multi-million-point rolling-technique runs. Both are real, both have verified leaderboards, both have surprisingly active communities. After a Tetris session, the Chrome Dino game is a different kind of reflex test — fewer pieces, more cactus.
