Rules & objective
Eat food, grow your snake and avoid walls and your body.
- Press Start to begin movement. The snake keeps moving at the chosen tier’s fixed pace until you pause or the run ends.
- Eating food increases the score by 10 and lengthens the snake. A collision with a wall or the body ends the run.
- You cannot reverse directly into yourself. To travel back in the opposite direction, turn around through open space.
Key terms
- Head
- The leading square whose direction you control.
- Tail
- The trailing end that moves away as the snake advances.
- Escape route
- Open space you can still reach after entering an area.
