One Line.
Three rounds. One unbroken stroke per drawing. The AI tries to name what you drew. Closer to its top guess scores higher.
One Line is a creative game built for the short window between meetings. The round is self-paced, with 1 attempt before the score locks. Make something nobody else would have. The team-wide leaderboard rebuilds itself daily, so the only thing carrying from yesterday is bragging rights.
