This room is relatively trivial to kill the snake.

BUT...

There's also the "challenge" version: get it to kill itself in the southern entrance rather than the dead end.

How do you manage to do that?

You have to take advantage of snakes' movement rules. They move straight towards you if you're in line with them, but otherwise they try to move horizontally towards you on turns ending in 0-4, vertically on turns ending in 5-9. If their first-choice move is blocked, they don't try the other direction towards you, but instead try N, E, S, W in that order.

It follows that it's fairly easy to trick a snake into moving N or E away from you. In this case, you want the snake to be to the north and coming south towards you; then you step west when it's on a vertical preference turn (the snake will move south, level with you); then you step north, and the snake's vertical move towards you is blocked by its own body, so it moves east.
