The classic — eat, grow, and don't crash into the walls or yourself.
Snake
Arrow keys / WASD · swipe on mobile
Snake is one of the most recognisable video games ever made — a single line that grows each time it eats, until the board becomes a maze of your own making. The rules take five seconds to learn and a lifetime to master: steer the snake to the food, avoid the walls, and above all avoid running into your own ever-lengthening tail. This version plays instantly in your browser with keyboard, on-screen controls, or swipes on a phone, and remembers your best score.
It is deceptively strategic. Early on you can move freely, but as the snake lengthens, every turn commits you to a path, and good players think several moves ahead to leave themselves an escape route. Everything runs locally in your browser — no download, no account, no ads interrupting the game.
