One Liner: Draw & Guess
Don’t lift the pen. Draw each word in one unbroken line, and the moment you lift your finger, the AI judges your drawing. Race a friend on a 60-second clock, or see how far you get in Challenge.
One Liner is a drawing game where every drawing is a single line: no second stroke, no eraser, no going back. Can you draw a giraffe, a teapot or a pair of scissors without lifting, so that the AI knows what it is?
See it in action
Play a friend
- Open a room and send its code, its QR code or a link. Your friend joins in seconds.
- Each of you picks 5 words for the other to draw, from a hand of random words — or let Pick for me choose.
- Draw at the same time on a 60-second clock, and watch your friend’s line appear as they draw it.
- 3 tries per word. Most words passed wins; on a tie, whoever got there first. Then hit Rematch.
Challenge
Every word in the game, each once, in your own random order. Three misses and you’re out. Climb the Game Center leaderboard: most words passed, then fastest time. Your best run is kept on your device too, whether or not you use Game Center.
Practice
Five random words in 60 seconds, three tries at each. No pressure, no ranking.
The AI judge
- Your drawing is judged right on your iPhone or iPad, the moment you lift. Nothing is sent away to be judged.
- Over 100 words: animals, food, faces, everyday things and a few surprises.
- Missed one? See what the AI thought you drew.
- The AI only guesses what you drew. It never makes any art: every line is yours.

The details
iPhone and iPad, iOS 17 or later. Draw with your finger, or with Apple Pencil on iPad. English, French, German, Spanish, Japanese and Simplified Chinese. No account to create; playing a friend needs an internet connection.
The AI learned to read drawings from Google’s Quick, Draw! Dataset (CC BY 4.0), whose doodles were joined into single lines to train it.
Put the pen down, and don’t lift it.
