👨‍🏫 Teacher mode Host the room — no bot, just controls (pause, step, slower, faster, reset). 👑 King snake Snake eats snake — the bigger snake always wins:
• Head-on-head: bigger eats smaller. Equal length → both die.
• Head-on-body: bigger (or equal) eats smaller; smaller passes through.
• You can also pass through your own body — no self-collision in king mode. 🌫️ Fog of war Bots only see what's near their own head. Real strategy — your nextMove(state) gets filtered state.others and state.foods. ⚔️ 1-on-1 duel Just you vs one mystery bot on the small Challenge board (24×24, 5 foods). Survive longer — or be the longest snake after 1000 ticks — to win. The bot is one of three secret styles, picked at random. Can you tell which, and beat it? 🎮 Play it yourself Skip the code — drive your snake by hand with the arrow keys / WASD or by touching the board (just like v2). Works in any room, duels included.

🧠 Your bot code

One function is your snake's whole brain. Every tick the game calls it with what your snake can see, and it answers with a direction.

nextMove(state) → 'UP' · 'DOWN' · 'LEFT' · 'RIGHT'

Whatever you return is the square your head steps into next.

state.me	{ body, direction, alive }	your snake — the head is body[0]
state.foods	[{x, y}, …]	apples (fog mode: only the ones you can see)
state.others	[{ body, direction, alive }, …]	every rival snake
state.board	{ width: 60, height: 60 }	the world — walls at the edges
state.tick	418	heartbeat count
returns	'UP'	one of the four direction strings
