How complex can a game truly be?
Have you ever thought that a simple game created in the 1980s, like Tetris, could present such a grand challenge even for today’s supercomputers or mathematicians? Yes, that’s exactly the case.
🔹 A Game That Made History
In 1984, Soviet programmer Alexey Pajitnov created a small video game—Tetris. Various shaped blocks fall from the top, and players must arrange them so that the rows fill up and disappear. That little game became a global sensation. In the 90s, Tetris was an addiction for many, with eyes glued to the Game Boy screen.
But behind this game lies a world of complex mathematical and computational mysteries—some of which are categorized as unsolvable problems.
🔹 Simple Game, Complex Mathematical Structure
If you think Tetris is just a game, you’re mistaken. From the mathematician’s perspective, it is an extremely complicated puzzle both geometrically and computationally.
The main goal of Tetris—filling a fixed empty area with different blocks—is a kind of Parquet Problem, where you try to completely cover a space using tiles of specific shapes.
These types of problems fall under a branch of mathematics called “complexity theory.” This field studies how difficult a problem is to solve and how much computational power is required.
🔹 The P vs NP Problem and Tetris
In complexity theory, problems are mainly divided into two classes:
- P class: Problems that a conventional computer can solve quickly.
- NP class: Problems that are hard to solve, but if given a possible solution, it’s relatively easy to verify.
The question has also been raised for Tetris—if you knew in advance exactly which blocks will come and in what quantity, could you clear the board entirely? The answer isn’t so straightforward.
In 2003, researchers at the Massachusetts Institute of Technology (MIT) proved that Tetris can be compared to an NP-Complete problem—specifically, the Three-Partition Problem.
🔹 What is the Three-Partition Problem?
Suppose you’re given some numbers, like {1, 2, 5, 6, 7, 9}. Can you divide these numbers into three subsets so that the sum of each subset is equal (for example, 15)?
Example: {1, 5, 9} and {2, 6, 7}—both sums are 15.
This problem is so difficult that it is NP-Complete. Researchers showed that this problem is mathematically equivalent to the problem of clearing the Tetris board. That means, if you can solve the Three-Partition Problem, you can solve the Tetris board-clearing problem—and the reverse is also true.
🔹 Tetris: A Game That Outsmarts Computers
These problems are not just hard—they have also been proven to be undecidable.
In 2004, two researchers from Leiden University in the Netherlands—Hendrik Jan Hoogeboom and Walter Kosters—conducted a study on Tetris’s I-shape block. They posed the question: If given exactly 40 I-blocks and their placement, is it possible to clear the board?
The answer is—this question is as complex as Gödel’s Incompleteness Theorem, and there is no definite answer—not even with infinite computational power!
This is a mathematical problem with no definitive solution or proof of impossibility—it is undecidable.
🔹 But Tetris Players Don’t Worry About All This!
Yes, none of this complexity comes to mind when you’re immersed in play. In real life, the blocks fall so quickly that you scarcely have time to think about them.
But research has shown—Tetris is not just fun, it’s a mathematical puzzle as well.
🔹 A Teenager Breaks the Record
Until 2010, Level 29 was considered the ultimate stage in Tetris. But in 2023, a 13-year-old player used a special technique called “Rolling” to reach as high as Level 157—so high that the game itself crashed!
“Rolling” is a kind of finger movement technique that allows extremely rapid input.
This incident shows—that when mathematical complexity is too great even for computers, humans can open new doors of possibility through ingenuity.
🔹 The Future of Games in Science and Math
Tetris isn’t just a part of history; it remains an area of research for mathematicians and computer scientists. Its complexity proves that within a simple game can hide extraordinary mathematical problems.
We often hear—math is hard, games are a waste of time. But Tetris shows—a game can actually inspire mathematical exploration.
🔹 Conclusion: The Allure Lies Not in Simplicity, but in Underlying Complexity
Tetris teaches us not to disregard something just because of its apparent simplicity. Sometimes, behind that simplicity hides an immense mathematical universe.
So, next time you’re guiding a Tetris block down, remember—you’re not just playing a game, but engaging in the great mathematical battle!
