Score Chasing, Speedrunning and Community Records

A game with no ending produces a different competitive culture to one with a finish line.

Most games are speedrun: reach the end as fast as possible. A game with no end cannot be, so its competitive culture developed differently.

What is competed on instead

Maximum score, which in older versions runs into the ceiling imposed by the counter's size.

Maximum level, which in some versions runs into the game's arithmetic breaking down entirely.

Lines cleared within a fixed count, usually forty, which is the closest thing to a conventional speedrun the genre has.

Head-to-head, which became the dominant competitive format precisely because the solo objectives are open-ended.

The forty-line sprint

The one true speedrun: clear forty lines as fast as possible from an empty board. Times are measured in seconds, the best under half a minute, and it is a pure test of placement speed and efficiency with no survival element at all.

It became the standard benchmark because it is short, comparable and entirely skill-dependent.

Breaking the game as an achievement

In older versions, the interesting record is not a score but a failure state. Push a 1989 build far enough and the colour palettes run off the end of their table, and past a certain level the program can crash outright.

Reaching that crash became a recognised goal, and it was achieved on stream in December 2023 after decades of being assumed impossible for a human.

That is an unusual kind of record: not finishing the game, but exceeding what its authors could conceive of.

Verification

With no built-in replay system, records are generally established by video — uncut footage, visible inputs, and increasingly a camera on the hands, since several of the techniques that matter are physical.

What TETERI offers

A best score stored on your own device, and nothing else. No leaderboard, no account, no verification. That is a deliberate consequence of collecting no data, and it means the only person you are competing with is yourself.
