1
Read the opening clue. The element speaks in riddles. Sometimes that's all a sharp detective needs.
2
Buy investigations to narrow it down. Each clue costs points — but stronger clues cost more. Cheap ones are broad; expensive ones are almost decisive.
3
Name your suspect. Search, or tap it on the periodic table. Once you've bought the family clue, matching elements light up to help you find them.
4
Guessing is a gamble. A wrong accusation costs more than any clue — but it does tell you whether the true element sits higher or lower on the table.
5
Solve it, keep the points, collect the card. Build your own living periodic table, one element at a time — then investigate another.
