What is Snake Game?

Guide a growing snake to eat food while avoiding walls and your own tail. Use arrow keys or swipe on mobile to steer. The snake gets longer with every piece of food, so each move gets trickier.

Pick a Small (15x15), Normal (20x20), or Large (25x25) board and one of three speeds (slow tick is 340 ms, medium 140 ms, fast 80 ms). A short 3-2-1 countdown gives you a beat to get ready before the snake moves. Arrow keys or the on-screen d-pad steer on a keyboard, swipe or the d-pad on a phone. Each food pellet adds one segment and one point; bumping into a wall or your own tail ends the run. Switch between Classic, Forest, and Neon colour themes, turn on No walls to wrap edge-to-edge, or Progressive speed to make the snake gradually quicker with every bite. The best score stays saved between visits, and the game-over screen shows your length and elapsed time plus a Share button that copies your final score.

How to use

1. Press 'Start' or tap the play button to begin. Use arrow keys (desktop) or swipe gestures (mobile) to steer the snake.
2. Guide the snake to eat the food that appears on the board — each piece makes the snake grow longer and increases your score.
3. Avoid hitting the walls or the snake's own body. Try to beat your high score with each new game.

When to use

• Killing a quick break without installing anything or signing in.
• Teaching a young player simple spatial planning and cause and effect.
• Practising reaction time at the fast speed without the noise of mobile-game ads.

Result

You start with a 3-segment snake. After eating 15 pieces of food, your snake is 18 segments long and weaving carefully through tight spaces. One wrong move and it's game over at 150 points — can you beat it?

FAQ

What's the maximum score, and does grid size change it?

It depends on the board you pick. Small (15x15) has 225 cells, Normal (20x20) has 400, and Large (25x25) has 625. The snake starts at length 3, so the theoretical ceiling is the cell count minus 3 — fill every square and there's nowhere left to move. Most players plateau well below that once the turns get tight; a smaller board hits its ceiling sooner.

How does the difficulty change between slow, medium, and fast?

Each speed only changes the time between steps: 340 milliseconds for slow, 140 ms for medium, 80 ms for fast. The grid and the snake length stay the same. Fast is roughly the original 1976 arcade Blockade speed; slow is forgiving enough for first-timers. Turning on Progressive speed shaves a few milliseconds off the interval after each food, down to a 55 ms floor.

Why can't I reverse direction into my own body?

If you're heading right and tap left, the move is blocked because the second segment is already to your left — instant self-collision. The input layer ignores 180-degree flips; you have to turn 90 degrees first.

Can I queue up a turn before the next tick?

Yes. The next direction is buffered until the next step, so a quick down-then-right combo registers cleanly even at fast speed. Only the most recent valid press counts, so accidental double-taps don't accumulate.

Where is the high score stored?

On this device, not on any server. Clearing site data or switching device resets it. The game runs without any account, login, or ad SDK loaded.
