Goal
Hold as much of the map as you can and knock out as many opponents as you can. The game is endless: no rounds, no timer, someone is always playing in the room. Your score is the highest percentage in one run and your knock-outs.
Trail and loop
- Your head always moves forward; you only change its direction. A 180° turn is not possible.
- Every cell outside your own land gets a trail, including cells on other players’ land.
- Return to any cell of your land and the loop closes: the trail and every cell enclosed by it and your land become yours.
- Other players’ land inside the area is taken too. Their trails on it stay in place and can still be crossed.
Who gets knocked out and when
| Event | Result |
|---|---|
| You cross someone’s trail | the owner is out, you carry on and it counts as your knock-out |
| You cross your own trail | you are out |
| Two players cross each other’s trails at the same moment | both are out |
| Head-on: entering the same cell or swapping cells | the smaller territory is out; if equal, both |
| All your land is taken | you are out and it counts for whoever took it |
| Getting home and having your trail cut on the same step | the cut wins: the loop does not close |
When you are out your land becomes free for anyone to claim. Restarting is instant and free, on a new spot away from the others.
Walls
Walls do not kill. At a wall your head turns sideways: away from your own trail, or towards the roomier side if both are free. That stays fair with network lag: a 200 ms ping will not knock you out at a wall. You can ride along a wall.
Controls and connection
- One turn happens per step; two quick commands are not lost, the second runs on the next cell.
- If your connection drops or you leave the page, your head goes home on its own and waits 20 seconds. If you do not return, the run ends and your land becomes free.
- A room with no people left stops and closes.
FAQ
Does it count on the leaderboard if a bot gets me?
The board records your largest territory in that run and your knock-outs, whoever got you. Bots themselves never appear on it.
If I surround another player, are they out?
No, only their land is taken. They are out only if all their land was inside, leaving them with nothing.
Why does my head wait at the start?
To give you a moment: it waits until your first command or about one second. Whichever way you turn, it starts at once.
