Six bots, one round, recorded from the shipping build at seed 20260903. The seed makes it the same round on every load.

The only control

Left half, right half.

Hold the left side of the screen to turn left, the right side to turn right. Let go and you go straight. Your curve is turning or it isn't. All the skill is in when.

The only way through

Every few seconds, your curve stops drawing.

That leaves a hole behind you, and holes are the only openings in a board that keeps filling up. A hole is 15.4 units of arena. Your head is 4. Take a collision radius off each edge and you have 7.4 units to aim at, at 84 units a second.

What it doesn't do

Nothing to sign up for. Nothing to type.

The short version of the privacy policy. The full one takes a minute to read.

  • No account
    No sign-in, no email, no profile. Open it and play.
  • No ads, no purchases
    Nothing is sold inside the game and nothing is sold about you.
  • No tracking
    No advertising ID, no analytics SDK. This page loads no third-party fonts, scripts or pixels either.
  • No chat, no name to type
    Your name comes from two fixed lists of 128 words. Nobody can send you anything.
  • Colour is never the only signal
    Every seat carries a shape as well as a colour: circle, square, diamond, star. Red and green look alike to one man in twelve.
  • One button deletes it
    Your records, your name and every row you own on the board, gone from the server on the spot.
