Why play
Benefits of playing
PRESSED teaches by making you predict and then check. Nothing is memorised from a card.
Subtractive colour mixing, empirically
Shade cards never show their recipe. Players reason from the absorption chart printed on their board, say the recipe out loud, then flip the card to check. A wrong guess costs nothing, so kids guess constantly. Expect the predict-test-observe loop to run fifteen to twenty times per player per game.
Stoichiometry you can hold
The Kiln turns two yellow chips into one red chip and one water token, because 2 FeO(OH) → Fe2O3 + H2O demands it. The water token exists so the right-hand side of the equation is an object you hold rather than a symbol you skip.
Diagnostic reasoning
Every other mechanic runs forwards, from ingredients to outcome. Fault cards run backwards: a cake crumbles, a surface glazes over, a colour goes chalky — and the player has to name the cause before flipping the card. Reasoning from symptom to mechanism is the harder skill and the one closer to real science.
Nomenclature by repetition
Nobody is asked to understand a formula beyond the Atom Key. They are asked to read formulas constantly — Fe2O3, TiO2, FeO(OH) — until recognition follows frequency, the same way dinosaur names do.
The transfer test
After two games, hand a player a real eyeshadow palette and ask them to read the ingredients aloud. If they recognise four compounds and can say what two of them are for, the game worked.
Why cosmetics?
PRESSED exists to show that chemistry is not a subject that lives in formulas and balanced equations. It is the reason an eyeshadow stays on your eyelid, the reason rust is red, and the reason two yellow powders heated together turn into something else entirely. We chose cosmetics because they are ordinary, familiar, and sitting on a shelf in almost every home — which makes them the perfect place for a young player to discover, first-hand, that the natural sciences are not abstract at all. They are in every single thing around us, down to a pressed pan of powder. The goal is depth and meaning: a player who finishes a game of PRESSED should look at the world and see chemistry everywhere, not just in a textbook.
