Periodic Table Game

Learn the periodic table by playing it.

Periodic Table Game turns all 118 elements into twelve short games you can
finish in a couple of minutes. No lectures, no flashcards to shuffle — just
rounds that get harder as you get better.

TWELVE WAYS TO LEARN

• Quick Pick — recognise an element from its symbol, name, family or mass
• Type It — spell the name from memory, no options to guess from
• Blitz — a three-minute sprint, as many as you can
• Elementle — six guesses at the day's element, the same one for everyone
• Table Hunt — find where an element sits on the chart
• Table Builder — place whole groups
• Higher or Lower — compare atomic number, mass, electronegativity or melting point
• Config Crafter — complete the electron shell configuration
• Symbol Speller — spell BACON, SILICON or BRUNCH out of element symbols
• Compound Lab — build water, rust, quartz and glucose atom by atom
• Match — pair symbols against names
• Daily Challenge — ten questions, seeded from the date

THE WHOLE TABLE, PROPERLY

Every one of the 118 elements carries its real data: atomic number, symbol,
name, molar mass, electronegativity, melting and boiling points, electron
shells, family, and a fact worth remembering. Browse the full chart by family,
by electronegativity trend, or by how much of it you have learned.

IT REMEMBERS WHAT YOU FORGET

Answer an element right and it moves up your mastery ladder. Miss it and it
comes back sooner. The chart on your profile fills in as you go, so you can see
exactly which corners of the table you still avoid.

THREE DIFFICULTY TIERS

Easy gives you 25 seconds, four choices and a hint. Hard gives you 9 seconds and
six. Impossible gives you 3 seconds, no choices at all and no hints — you type
it or you don't.

BUILT TO BE READABLE

A dyslexia-friendly typeface, colour-blind family glyphs so the chart never
depends on telling ten hues apart, text that respects your system size, and
full screen-reader labels on every cell of the table.
