20 × 20 arena

Grid Snake

One cell at a time. Walls and your own body are solid. The tail steps aside if you are not growing.

Ready — press Start.

Controls. ↑ ↓ ← → turn the snake. A reverse into the neck is ignored, even if several keys arrive before the next step. Start begins play. Pause / Resume freezes and continues. Restart restores the opening length, direction, score, food, and state.
