AtomixQuest
Pick the heaviest, the lightest or the exact element from a set of periodic table cards.
Every day: A daily set of periodic-table rounds, the same for every player: pick the element with the highest value, the lowest, or the exact target value, plus a wildcard round whose rule changes each day. New puzzle: Midnight UTC: the game files each day's puzzle under the UTC date.

AtomixQuest is a daily chemistry game about the periodic table. Each round shows a hand of element cards and asks which has the highest or lowest value of a property, such as atomic mass, melting point or electronegativity, or which matches an exact value. A streak boosts your points, and there are leaderboards, leagues and an archive.
About AtomixQuest
AtomixQuest turns the periodic table into a daily quiz. Every round deals a few element cards and asks one question about them: which has the highest atomic mass, which is the least dense, which has a melting point closest to a given number. The daily puzzle mixes Maximum, Minimum and Target rounds with a Wildcard round whose rule changes from day to day. The properties range from the familiar (atomic number, group, period, discovery year) to the specialist (ionization energy, specific heat, number of natural isotopes), and each comes with a short tip explaining the unit.
It is made by the same developer, C3-Peyo, as HeatmapQuest, CrossmapQuest and HistoriaQuest, and shares their system: points for each round, a streak that raises your score by 2% a day up to 25%, shields that protect a streak for one missed day, leaderboards, leagues and an archive of earlier puzzles. A weekly Survival mode sits beside the daily one.
It suits students, teachers and anyone who once learned the table and wants to see how much stuck. The data comes mostly from Wikipedia and public databases, as the site notes.
How to play AtomixQuest
- Open AtomixQuest and start the daily puzzle.
- Read the round's question, for example which element has the highest boiling point.
- Pick the element card you think answers it.
- See the real values revealed and your points for the round.
- Play every round of the day, then compare your score on the leaderboard.
Tips
- Use the table's trends: atomic radius grows down a group, electronegativity rises towards fluorine.
- Read the tip on each property for its unit before guessing an exact value.
- Play every day: the streak bonus adds up to a quarter more points.
