Build reaction chains, balance equations, and unlock 120+ elements in Chemority - where periodic table knowledge becomes your greatest weapon
Choose your starter pack and accelerate your molecular journey
Bonus elements require account creation. Lab boost applies to reaction speed mechanics. Chain reactions expire 30 days after activation. New players only. Educational content remains free regardless of bonus selection.
Chemority operates on a dual-layer puzzle system where you simultaneously manage element placement and reaction timing. Each of the 120+ elements behaves according to real periodic table properties - electronegativity determines bonding strength, atomic radius affects chain proximity, and valence electrons dictate how many connections you can form per turn.
The reaction engine calculates stability scores in real-time based on molecular geometry. Linear chains score differently than branched structures, while cyclic compounds unlock bonus multipliers. You must balance equation coefficients before triggering reactions - incorrect stoichiometry results in unstable compounds that decay after three turns.
Advanced levels introduce catalysts that modify reaction rates, pH indicators that alter element behavior, and temperature controls affecting molecular kinetics. The progression system unlocks new periodic table blocks as you master each element group, with transition metals and lanthanides requiring complex coordination chemistry strategies.
Complete periodic table from Hydrogen to Oganesson, each with authentic chemical properties. Alkali metals react explosively with water tiles, noble gases resist bonding, and radioactive elements decay over time creating strategic timing challenges.
Every reaction requires stoichiometric balance before execution. Drag coefficient numbers to balance reactants and products, with visual mass conservation indicators showing when equations achieve equilibrium. Failed balancing attempts cost energy points.
Construct linear, branched, and cyclic molecular structures using valence electron rules. Each bond type - single, double, triple - affects stability differently. Longer chains earn multipliers but increase instability risk requiring careful structural planning.
Manipulate temperature sliders and catalyst selectors to speed up or slow down reactions. High temperatures increase collision frequency but risk breaking weak bonds. Catalysts lower activation energy thresholds enabling previously impossible reactions.
Start with basic s-block elements and earn access to d-block transition metals, f-block lanthanides, and synthetic elements through puzzle completion. Each new periodic group introduces unique bonding mechanics and reaction patterns.
Reference database of 500+ real chemical compounds with 3D molecular models, physical properties, and real-world applications. Every compound you successfully synthesize in puzzles gets added to your permanent collection with detailed chemistry notes.
