Unlabeled is a daily puzzle game for people who like looking at data. Each day, you get four mystery charts. Your job is to figure out what each chart actually represents—without the usual labels that make charts easy to read. No title. No axis labels. No source line. Just the bare visual shape of the data and a set of clues to point you in the right direction.
It’s a simple format to pick up, but each puzzle is deceptively tricky. That’s the fun: the chart is right in front of you, and the answer feels obvious only after you’ve found it.
The Daily Format
Unlabeled runs on a daily cycle. Once a day, a fresh set of four charts appears at unlabeled.dev. You can work through them in any order, and you don’t need to bring anything from previous days. Each day is a clean slate with a new batch of puzzles.
Because there are four charts, you get a small variety of shapes and challenges. One might be a clean upward line. Another might be a messy cluster of points. The daily set gives you a little of everything without becoming overwhelming.
What Does a Mystery Chart Look Like?
A mystery chart is a data visualization stripped of its context. You might see a line that starts low, climbs steadily, and then dips sharply. Or bars of wildly different heights. Or a scatterplot with dots forming a striking pattern. The visual itself is completely visible—you’re just missing the labels that tell you what you’re looking at.
That missing context is the core of the puzzle. The shape of the data is your primary clue. A slow climb followed by a steep drop tells a story. A chart with repeating spikes suggests seasonality. A flat line with one huge outlier raises the question: what happened there?
The Clues Help You Narrow It Down
Alongside each chart, you get a few short text clues. The clues won’t give away the answer directly. Instead, they help you filter out impossible interpretations. They might suggest a time frame, a location, or a broad category like “weather” or “sports.”
The key is to combine the shape of the chart with the context of the clues. A line chart that climbs steadily could represent almost anything. But if the clue mentions “global population,” suddenly the shape makes sense. The clues are the bridge between the abstract visual and the real world.
How to Submit a Guess from the Clues Alone
When you’re ready to commit, you submit a plain-language guess describing what the chart shows. You might type something like “average monthly rainfall in Seattle” or “most-watched Netflix series by hours.” You don’t need to produce a perfect title—just a description that captures the subject, the place, and the time frame well enough to match the intended answer.
Your guess should come from the clues, not from looking the answer up. That’s the whole game: using the limited information you have to make an informed decision. If you’re wrong, the reveal shows you the labeled chart—and you’ll instantly see where your interpretation went off track. If you’re right, you get that great “aha” moment when everything clicks into place.
A Few Beginner-Friendly Pointers
- Start with the chart that sparks an immediate hunch. Your first impression often points you to the right pattern.
- Read the clues before overthinking the shape. They’re designed to steer you away from dead ends.
- Try describing the chart out loud. “It goes up, plateaus, then drops fast” is a useful observation even if it doesn’t identify the data.
- Keep your guess concise. A few words are usually enough to represent the underlying concept.
Why Four Charts a Day Feels Right
One chart might not be enough to build momentum, and a dozen would be exhausting. Four gives you a chance to practice, fail, and adjust in a single sitting. Each reveal sharpens your eye for the next chart in the set.
Unlabeled isn’t about being a statistics expert. It’s about looking closely at something incomplete and making a reasonable guess from the clues alone. That skill is surprisingly satisfying—and you get four chances to exercise it every day.
