You start on a small circle of ground that belongs to you. Everything outside it doesn't.
Head out, draw a loop, come back — whatever you enclosed turns your colour. That's the whole game. The catch is the ribbon you leave behind while you're outside: it's exposed, and anything that touches it ends your run. Your own ribbon counts. Cut someone else's and their entire territory disappears with them.
The arena wall doesn't kill you, it just pushes you along. So the edge is a place to hide, not a place to die.
Eight bots fill the empty slots and play by exactly your rules — same speed, same turn rate, same boost, no cheating. First to hold 70% of the arena takes the session.
One to nine players. Mouse or WASD. Space to boost.
