Play AtomixQuestA fresh puzzle is waiting for you.

AtomixQuest is a daily periodic-table puzzle that presents a single challenge each day based on elemental properties and values. Players receive a prompt that may ask for the heaviest or lightest element in a set, the odd one out, or the exact numeric value of an element property. The format changes daily to keep the puzzles varied while always centering on chemical elements.
The puzzles on AtomixQuest require knowledge of elemental attributes such as atomic weight, group, period, or other measurable values, but they are presented as short single-round challenges rather than multi-step games. Each day offers a different type of question so players face distinct reasoning tasks: comparative queries, categorical exclusions, or precise-value guesses. The site is available in English and French.
How to play AtomixQuest
- Open AtomixQuest and read the daily prompt that states the type of challenge for that day, such as finding the heaviest or identifying the odd one out.
- Examine the listed elements or properties provided in the puzzle to determine which attribute is being tested.
- Use known periodic table data like atomic weight, group, period, or common properties to narrow down candidate elements.
- Select or enter the element or value that answers the prompt and submit your answer to see whether it matches the daily solution.
Tips for AtomixQuest
- When the task asks for the heaviest or lightest, compare atomic weights rather than common names or uses.
- For odd-one-out puzzles, check group and period membership first, then consider atypical properties like radioactivity or state at room temperature.
- If the prompt requests an exact value, focus on standard atomic masses and consult a reliable periodic table memory or reference before answering.
- Practice by reviewing trends in the periodic table such as increasing atomic weight down a group and across a period to speed up decisions.
