Snake

Did you know the secret to beating Snake relies on an advanced mathematical concept? The game requires you to navigate a growing snake around a grid without hitting the walls or your own tail. Computer scientists solve the game using a 'Hamiltonian cycle'—a path that visits every square exactly once without crossing itself. Originally tracing its roots to the 1976 arcade game Blockade, Snake gained global fame when design engineer Taneli Armanto programmed it for the Nokia 6110 in 1997. Test your reflexes and spatial awareness by playing our browser-based version now.

1. Press the arrow keys (or swipe on mobile) to change the snake's direction.
2. Navigate the snake's head toward the food items that spawn randomly on the grid.
3. Watch the snake's tail grow one segment longer for every piece of food you eat.
4. Avoid crashing into the outer walls of the play area.
5. Avoid crashing into any part of your own tail as it trails behind you.
6. Keep eating food to increase your score until you trap yourself.

• The snake moves forward continuously at a set speed.
• You can only change its direction by 90 degrees left or right.
• You cannot stop the snake from moving.
• You cannot reverse direction directly into yourself (e.g., pressing Down while moving Up).
• Hitting a wall ends the game instantly.
• Hitting your own body ends the game instantly.

• Look at the entire board, not just the food. Plan your route to the food while ensuring you have a clear exit path.
• Hug the walls. Running along the outer edge keeps the center open for maneuvering.
• Follow a zig-zag pattern. When the snake grows very long, moving in tight, parallel lines maximizes your available space.
• Never rush into a blind alley formed by your own tail.
• Keep calm as the speed increases. Quick, jerky movements often lead to fatal mistakes.

• Classic (Walled): Standard mode where hitting the outer boundary ends the game.
• Wrap-Around: Moving through a wall teleports the snake to the opposite side of the screen.

• The controls require zero explanation—anyone can play instantly.
• You clearly see exactly why you lost every time, encouraging you to try again.
• The increasing speed and length provide a natural, escalating difficulty curve.
• It delivers pure arcade nostalgia.
