Snake is one of the simplest video games ever designed and also one of the most addictive. You control a line — the snake — that moves continuously around a rectangular arena. Food pellets appear at random positions on the board, and every time the snake's head reaches a pellet, the snake grows by one segment. The catch is that the snake can never stop moving, can never reverse direction, and can never run into a wall or any part of its own body without losing instantly.
The goal is straightforward: survive as long as possible and grow as long as possible. There is no time limit, no enemies, no power-ups in the classic version — just you, the snake, and your own decisions. Every second you live, the body gets longer, the arena gets more crowded, and the cost of any mistake gets higher. By the time the snake fills half the board, even routine moves feel like puzzles.
Snake first appeared as the 1976 arcade game Blockade by Gremlin Industries, but the version that made it world-famous was the one Nokia preinstalled on the 6110 phone in 1997. Throughout the late 1990s and early 2000s, hundreds of millions of people played Snake on Nokia 3210 and 3310 handsets, making it the first mobile game for an entire generation. Today, descendants like Slither.io, Snakebird, and countless web remakes keep the format alive.
The single most useful habit for beginners is to hug the perimeter rather than wandering through the middle. Walls give you a fixed boundary on one side, which means you only have to worry about the open side and your own body. Perimeter routes also leave the entire interior of the board free as escape space when the snake eventually grows long.
Cutting straight across the middle of the arena feels efficient when the snake is short, but it cuts the remaining open area into two disconnected halves. Once you've sliced the board in two, you've lost most of your future options. Long, smooth perimeter laps beat tight zigzags almost every time.
Pick one direction of rotation early — clockwise or counter-clockwise around the perimeter — and stick with it. Consistent loops are easier to maintain than random patrols and they make tail-tracking far simpler.
Strong Snake players don't think in single moves — they think in loops. Before every turn, ask: "If I go this way, what is my path back to safe ground?" Every move should be part of a curve that eventually returns the head to open space, with the tail trailing safely behind it.
The mental shift is from "where is the food?" to "where is my escape route?". Food that you can't safely return from is a trap, not a reward. Players who only think about the next pellet die quickly; players who think about the next two or three moves live a long time.
When the snake is long, the inner region of the board becomes a death trap. If the body wraps around an open pocket, the head can wander into that pocket and then have nowhere to go — every direction leads to the body. Always check whether the pocket you are entering has a clear exit large enough for your current length.
A useful rule of thumb: never enter a region smaller than your snake. If the pocket has twenty cells and your snake is forty segments long, you cannot survive there. Pass it by, even if it has food.
Beginners chase every food pellet the instant it spawns, often crossing the entire arena and breaking their pattern to do it. Experts ignore food that is far away and let the next pellet come closer. Only chase food when it's already near your natural path — when you can pick it up as part of a loop you were going to make anyway.
This is counter-intuitive because food gives you points. But food also lengthens you. Each pellet eaten makes the next turn slightly harder. A pellet you grab cleanly is a gift; a pellet you twist across the board for is usually a death sentence two moves later.
Desktop: Use the four arrow keys (↑ ↓ ← →) or the WASD keys to steer. Each key press immediately changes the snake's heading to that direction, except that you cannot reverse 180°.
Mobile / Tablet: Swipe anywhere on the screen up, down, left, or right to change direction. Short, decisive swipes work better than long lazy gestures.
The game runs full-screen on phones and adapts automatically to any screen size. We recommend portrait orientation on mobile for the most natural swipe area.
Snake's simple rules have inspired dozens of variants across web, mobile, and arcade platforms. The most popular include:
The classic single-player version remains the most popular by far. Start there to build the core instincts before trying the multiplayer variants.
The goal of Snake is to control a growing snake that eats food appearing on the play area. Every piece of food you eat makes the snake longer. You must avoid hitting the walls of the arena and, crucially, avoid running into your own tail. The longer you survive, the higher your score.
You score by eating food. Each food item is usually worth a fixed number of points and also adds one segment to the length of your snake. Some variants give bonus points for eating special items quickly or for surviving for longer periods of time without losing.
The Snake concept originated as a 1976 arcade game called Blockade by Gremlin Industries. Many variants followed, but the version that made Snake globally famous was the one Nokia preinstalled on the 6110 phone in 1997, and later on the Nokia 3210 and 3310 which sold hundreds of millions of units.
Technically, the maximum possible state is filling the entire board with the snake, leaving no empty cell. Reaching that state is extremely rare and requires near-perfect play across thousands of moves. Most players simply aim for a new personal best length or score rather than a final win condition.
The most reliable strategy is to hug the perimeter of the arena and move in predictable loops rather than cutting through the middle. This keeps a clear escape route open, prevents you from trapping yourself, and lets you safely eat food that appears near your path instead of chasing every item across the board.

Snake was preinstalled on Nokia 6110, 3210, 3310 and many other models from the late 1990s onwards. With hundreds of millions of those phones sold worldwide, Snake became the first mobile game most people ever played. For an entire generation it was the default way to kill time on a bus or in a queue.
