The classic grow-and-avoid arcade game. Steer your snake around a 20×20 grid, eating food to grow longer without running into your own tail.
Rules
Use the arrow keys or the on-screen D-pad to steer.
The snake moves continuously in the direction you last chose.
Eating food adds one point and grows the snake by one segment.
Running into your own body ends the game — the snake wraps around the edges of the grid instead of hitting a wall.
Tips
Leave yourself an escape route rather than boxing your own tail in — circling the outer edge is safer than cutting through the middle once you're long.
