Orbital Architect

Build atoms by filling electron orbitals. A gamified quantum chemistry puzzle where aufbau, Pauli exclusion, and Hund's rule are the game mechanics.

electron configuration quantum numbers aufbau principle orbital theory

Build atoms from scratch. Place electrons into orbitals following real quantum mechanical rules — get it wrong and the atom destabilizes. Watch 3D orbital shapes materialize as you fill them.

Game Modes

  • Campaign — Build elements from hydrogen to krypton across 36 levels of increasing complexity
  • Challenge Mode — Timed rounds: configure atoms as fast as possible for high scores
  • Sandbox — Free exploration with no rules. Break Pauli exclusion and see what happens.

Features

  • 3D orbital visualizations (s, p, d shapes rendered in real-time)
  • Drag-and-drop electron placement with quantum number feedback
  • Energy level diagram that updates as you build
  • Rule violation detection with educational explanations
  • Scoring, streaks, and achievement system
  • Periodic table integration
