Atomix: Atom Puzzle Game

Learn the first 20 elements of the periodic table, then use them. Read the table, drill the order, take the quiz, and bond atoms by their valence into 48 real molecules. In Korean or English. Free and offline.

Why Atomix is different

The periodic table is usually something you memorize and forget. In Atomix it is also the rule of a puzzle: every atom has as many bonds as its group allows, so knowing that oxygen sits in group 16 is how you work out that carbon dioxide needs two double bonds. Tap an atom and the app tells you exactly that.

• Periodic Table — the first 20 elements laid out as the real table, periods down and groups across. Tap any element for its symbol, number, mass, period, group, family and one fact worth knowing. Sodium and potassium carry their textbook names (소듐·포타슘) alongside
• Order Drill — tap the elements in atomic-number order: all 20, one period, one group, or one family. Wrong taps shake but never block you
• Quiz — ten questions per round on symbols, names, numbers, groups, periods and families. Atomix remembers what you keep missing and builds a review round from exactly those. Three correct answers make an element mastered

Molecule Puzzle

• Each atom shows how many bonds it still needs: hydrogen 1, oxygen 2, nitrogen 3, carbon 4
• Tap two atoms in the same row or column to bond them, tap again for a double or triple bond
• Bonds cannot cross, and a molecule is complete when every atom is satisfied and all of them are connected
• 48 real molecules in three packs. Basics runs from water and ammonia to acetylene, acetic acid, urea and glycine. Carbon Chains adds propane, propene, propyne, dimethyl ether, acetonitrile, formamide and more. Table Friends brings in silicon, boron, phosphorus, sulfur and the halogens: silane, boron trifluoride, hydrazine, nitrous acid and others. Every board has exactly one solution
• Finish one and you get its formula, its name and a fact about it

Today

Every day the home screen picks one molecule to build and three quick questions from the elements you miss most. Done is done: no streaks, no notifications.

Collection and progress

• Elements you answer correctly in the Quiz or build into a molecule are saved to your Collection with their atomic number, atomic mass and a one-line fact
• The home screen's progress card shows all 20 at a glance: mastered, collected or still unknown
• Korean or English, chosen in Settings; the app follows your device language by default

Free, offline, private

• No ads and no in-app purchases
