Every game we're building.
Each game targets specific chemistry topics and uses a named learning-science mechanic. The catalog below is the source of truth as we build them out one by one.
Build & construct
4 gamesThe student produces the answer. Highest learning yield per minute (Bjork generation effect).
- Live
Build-a-Molecule
Drag atoms onto a canvas; valence rules snap them into Lewis / VSEPR shapes. The cornerstone game — five sub-skills in one mechanic.
- Topics
- Atomic theory · Bonding · Molecular geometry
- Mechanic
- Generation effect
- Live
VSEPR Shape Fitter
Rotate 3D molecules into the matching geometry slot — linear, bent, tetrahedral, and friends. Lone pairs render as visible clouds.
- Topics
- Bonding · Molecular geometry
- Mechanic
- Spatial generation
- Live
Concept Map Builder
Drag-and-connect concept nodes — electronegativity → bond polarity → molecular polarity → solubility. The chain glows when correct.
- Topics
- Cross-cutting
- Mechanic
- Elaboration
- Live
Decay Chains
Plot α / β / γ arrows from a starting isotope to a stable nuclide. Half-life shown as a fading node — time made visual.
- Topics
- Nuclear chemistry
- Mechanic
- Procedural retrieval
Practice & drill
4 gamesRepetition for fluency. The unglamorous backbone the rest of the games feed into.
- Live
Spaced Repetition
Anki-style cards with expanding intervals. Items are tagged by topic so sessions can be focused or interleaved.
- Topics
- All units
- Mechanic
- Spaced retrieval
- Live
Memory Match
Flip-a-card matching grid. Polyatomic ions ↔ charges. Formulas ↔ names. Indicators ↔ pH ranges.
- Topics
- Periodic table · Bonding · Acids & bases
- Mechanic
- Paired-associate retrieval
- Live
Reaction Sort
Drag balanced equations into 5 reaction-type bins. Speeds up as you go. Builds the recognition that gates predicting products.
- Topics
- Reactions · Stoichiometry
- Mechanic
- Pattern recognition
- Live
Periodic Table Pong
Pong, but the paddle is an alkane that grows when you answer right. Element symbols, names, and ions — A/S/D/F keys or your voice. Solo vs AI, multiplayer coming.
- Topics
- Periodic table · Atomic theory
- Mechanic
- Retrieval under time pressure
Solve & investigate
4 gamesHypothesis, test, refine. High intrinsic-motivation yield (SDT: autonomy + competence).
- Live
Stoichiometry Kitchen
"Make 5 moles of water." Pick masses, balance equations, find the limiting reagent. The kitchen scale is the metaphor.
- Topics
- Stoichiometry · The mole · Reactions
- Mechanic
- Chained elaboration
- Live
pH Detective
Mystery solutions arrive at the lab. Predict pH, classify strength, simulate neutralization. Wrong answers reveal the misconception.
- Topics
- Acids & bases · Solutions
- Mechanic
- Hypothesis testing
- Live
Gas Law Lab
Sliders for P, V, T, n on a piston-cylinder. Predict the curve before you slide. The animation is KMT.
- Topics
- Gases · KMT
- Mechanic
- Predict-then-test
- Live
Daily Mystery Experiment
60-second "what happens when…?" prompt every day. Curiosity-driven re-engagement instead of streak shame.
- Topics
- Rotates
- Mechanic
- Spaced prediction
Collect & compete
3 gamesLong-horizon progression. Octalysis drives: Accomplishment, Ownership, Empowerment.
- Live
Periodic Quest
Civ-style map. Unlock elements by clearing challenges in their group. Each unlock reveals a portrait card. Eventually replaces the home page.
- Topics
- Periodic table · Periodic trends
- Mechanic
- Progression + spacing
- Live
Element TCG
Earn element cards through study. Deck-build with synergies — halogen + alkali metal triggers an ionic combo. Stats are real properties.
- Topics
- Periodic trends · Bonding · Reactions
- Mechanic
- Interleaved retrieval
- Live
Catalyst
Categories mirror chemistry units. Solo and classroom multiplayer modes. The first game a teacher will project on a screen.
- Topics
- Rotates by category
- Mechanic
- Cued retrieval
