Why Tetris Still Matters

Tetris isn’t just a game; it’s a cultural phenomenon. Since its debut in the 1980s, it has captivated generations with its elegant simplicity. Unlike many modern games that demand hours of time and attention, Tetris is perfect for micro-moments — short breaks, focused challenges, and mental resets.

Studies show that playing Tetris can boost spatial reasoning and relieve stress — scientifically justified “productive procrastination.”
