Wordle for science · one puzzle a day · no account
Six guesses to find the hidden element, planet, animal, or number. Every guess shows how its real properties compare with the answer, so you learn the periodic table, the solar system, the animal kingdom, and the numbers 1 to 100 by playing.
Works on phones, tablets, and Chromebooks. Nothing to install.
Iron was close on atomic number and the answer was higher. Zinc was one group too far. Copper, atomic number 29, in three.
Same daily rhythm, same six guesses, same shareable grid. The difference is what the colors mean.
Elements, Solar System, Animals, or Numbers. Each has its own daily puzzle, and everyone gets the same one.
Type any element, body, animal, or number. The board compares five of its real properties with the hidden answer.
Green is an exact match. Yellow is close. Arrows say whether the answer is higher or lower. Six guesses, then the reveal and a fact worth remembering.
No trivia-night gotchas. Every clue is a measurable property, in the units scientists actually use.
Atomic number · Period · Group · Category · State at room temperature
After a week you stop seeing the periodic table as a list and start seeing it as a map. Noble gases on the right, alkali metals on the left, and a feel for where everything else sits.
44 elementsType · Distance from the Sun (AU) · Diameter (km) · Moons · Rings
Planets, dwarf planets, and the big moons. You will learn that Ganymede is larger than Mercury, and that Saturn has more moons than every other body combined.
23 bodiesClass · Diet · Legs · Mass (kg) · Lifespan (years)
From a honey bee to a blue whale, nine orders of magnitude of mass. A quiet lesson in classification and scale, and the reason a tortoise outlives a tiger.
37 animalsValue · Parity · Prime or composite · Digit sum · Number of divisors
Number sense without a worksheet. Players start noticing that primes have exactly two divisors and that squares always have an odd number of them.
