The rules, what the tiles mean, and how to find the answer in fewer guesses.
Every day Cosmodle picks one mystery object from the sky. It could be a planet, a moon, a comet, a star, a galaxy, a black hole, even a supernova. You get 15 guesses to name it. There is no multiple choice and no list to scroll through: you type the name of anything in the catalogue, and the game tells you how your guess compares with the answer, one property at a time.
| Correct | An exact match, or within 2 percent for a number and within 3 degrees for a temperature. |
|---|---|
| Close | Within 15 percent for a number, or within 25 degrees for a temperature. |
| Higher | The answer's value is bigger than your guess's. |
| Lower | The answer's value is smaller than your guess's. |
| Incorrect | A yes-or-no property, like type or rings, that does not match. |
| N/A | The property does not apply to one of the two objects. A constellation has no mass of its own, and a black hole has no visible brightness. |
The percentages are relative, not absolute. Being "close" on the distance of a galaxy 2.5 million light years away means being within a few hundred thousand light years of it, while being close on the distance of a planet means being within a fraction of an astronomical unit. That is deliberate: it keeps the tiles fair across objects whose sizes differ by a factor of a trillion.
Guesses do not have to be the same kind of object as the answer. Where a property can be worked out for both, the game does it for you: distance from the Sun in astronomical units and distance from Earth in light years describe the same thing, so a star guessed against a planet still gets an arrow. Only a property one object genuinely does not have comes back N/A.
You get one free hint before your first guess. After that the Hint button reveals another of the answer's properties, up to 8 more, and one extra free reveal arrives every four wrong guesses. Hints start with whichever property narrows the field most and skip anything you have already pinned down with a correct tile. Numbers are shown as a range rather than an exact figure, so a hint tells you the scale without giving the answer away.
Hints cost nothing. A win is a win however many you used, and it still extends your streak.
The single most useful tile is Type. Knowing the answer is a moon rather than a star removes most of the catalogue at once, and it tells you which properties are going to matter. If your free hint does not settle it, a first guess from the middle of the scale, such as a nearby star or a large planet, usually shows you from the distance arrow alone whether the answer lives in the solar system, elsewhere in the Milky Way, or in another galaxy entirely.
Distances in Cosmodle span from a few hundred thousand kilometres to more than thirteen billion light years. Rather than creeping upward one object at a time, jump by a factor of ten or a hundred. A rough ladder helps:
Once you know the type, treat each numeric arrow like a number guessing game. If the answer is a star further than Sirius but closer than Rigel, your next guess should sit roughly halfway between them, not just past Sirius. Two or three well-placed guesses can pin a distance down to the "close" band.
Some properties are yes-or-no rather than numbers: rings, zodiac membership, hemisphere, galaxy type, the planet a moon orbits. Once one of those turns correct it cuts the remaining candidates sharply. For a moon, the parent planet is often the fastest way in; for a constellation, hemisphere and zodiac membership narrow 88 candidates to a handful.
Practice mode gives unlimited random rounds that do not touch your statistics. It is the quickest way to get a feel for how big, how hot and how far away things are, which is most of what the daily puzzle is really testing.
Giving up on the daily puzzle shows the answer and resets your streak, but it is not counted as a loss, so your Played count and Win percentage stay where they were.
