How to Get Better at Tetris + Its 35-Year History

Tetris is probably the most-played game in history. Estimates put the total number of games played across all platforms at over 5 billion. It has been on more devices than any other game — Game Boy, NES, mobile phones, calculators, and famously, an oscilloscope. And it was created by one person, in 1984, in the Soviet Union, on a computer most people in the West had never heard of.

The game is also deceptively deep. Most people plateau at a level where they can survive for a while but never push into high scores. The gap between an average player and a good one almost entirely comes down to two things: how you stack and how you think ahead. Here is what actually helps.

The history: one programmer, one computer, 1984

Alexey Pajitnov was a computer scientist at the Soviet Academy of Sciences in Moscow. In June 1984, while working on a program to test a new computer (the Electronika 60), he wrote a puzzle game inspired by a physical puzzle called Pentominoes. He called it Tetris — a combination of "tetra" (Greek for four, referring to the four-block pieces) and "tennis," his favourite sport.

The game spread through the Soviet computing community on floppy disks, then reached Hungary, then somehow found its way to a British software company called Mirrorsoft, which licensed it to Nintendo. The Game Boy version, released in 1989, was bundled with the hardware in most markets — and sold 35 million units. Pajitnov received no royalties for any of this. The Soviet government owned the rights. He only began receiving royalties in 1996, after the Soviet Union had dissolved.

The game has since been adapted for over 65 platforms and is estimated to have sold over 520 million copies. The 2023 film Tetris tells the story of the legal battles over the rights.

Why most players plateau

The most common mistake is reactive play — you wait for a piece to fall, look at your pile, and then decide where to put it. By the time the piece is halfway down, you're already behind.

Good players think about where the next piece is going while the current one is still falling. Almost every version of Tetris shows you a preview of the next piece. Use it. Decide where the current piece goes based partly on where you want the next one to land.

Practical tips that actually work

1. Keep your stack flat and low

The #1 goal in Tetris is to survive. A flat, even stack gives you more options for every piece. Tall, uneven stacks create gaps that are almost impossible to fill later. If your stack is getting uneven, spend a few turns flattening it even if you can't clear a line.

2. Leave a column open on one side for the I-piece

The long straight piece (the I-piece) is the only one that can clear four lines at once — a "Tetris." Keeping one column open on either side of the board means you can always drop an I-piece for a big clear. This is the single most effective strategy for scoring.

3. Don't leave holes under filled rows

A hole is any empty cell with filled cells above it. Holes are almost impossible to fill without clearing the rows above them first — and clearing those rows is harder because you have to fit pieces around the hole. One hole quickly becomes a cascade problem. Avoid creating them at all costs.

4. Rotate before you drop

Get into the habit of deciding the rotation and horizontal position of a piece early — before it gets close to the stack. Rotating at the last second leads to misplacements. Make the rotation decision at the top of the screen, then steer.

5. Clear lines continuously, not in bursts

It is tempting to let the stack build up and wait for a big Tetris clear. But this strategy is risky — the stack might get out of control before the I-piece arrives. Clearing one or two lines steadily is more reliable than going for four-line clears at high risk.

The T-spin: the technique that separates good players from great

A T-spin is a technique where you rotate the T-piece into a gap it could not slide into from above. It requires setting up a specific shape in your stack — a T-shaped hole with enough room to spin the piece in — and then dropping the T-piece and rotating it at the last moment so it fits into the gap.

In competitive Tetris, T-spins are worth more points than regular line clears and can chain together for massive combo scores. They require deliberate setup — you have to build the receiving shape while also managing the rest of your stack.

For casual play, you don't need to master T-spins. But understanding why they exist — that you can rotate pieces into positions they couldn't reach by dropping straight down — opens up more creative placements and keeps you from panicking when the S and Z pieces (the hardest to place neatly) arrive.

Why the Game Boy version was so important

The Game Boy launched in 1989. Nintendo initially planned to bundle it with Super Mario Land, but at the last minute chose Tetris instead — reasoning that the game would appeal to a wider audience, including adults and older players who might not be interested in Mario. They were right.

Tetris became the game that defined portable gaming. For many people in their 30s and 40s today, the Game Boy is Tetris. The simple music — a Russian folk song called Korobeiniki — is one of the most recognizable pieces of video game music ever written. Pajitnov chose it because he wanted something that felt connected to the game's Soviet origins.
